Maryland DUI Law in 2026: A Complete Guide to Penalties, License Suspension, and Defense

If an officer pulled you over and the conversation turned to how much you had to drink, you are now staring down two parallel cases: a criminal prosecution under Maryland Transportation Article Section 21-902, and a separate administrative case at the MVA under Section 16-205.1. Both can take your license. Both can hurt your record. And both have deadlines that started ticking the moment the officer handed you that yellow DR-15A at the roadside.

This guide walks through how Maryland’s DUI laws actually work in 2026, what the penalties really are, how the criminal and MVA processes interact, and where cases get won and lost. Maryland law enforcement files thousands of impaired driving charges every year, and the rules around stops, testing, license consequences, and ignition interlock have grown more demanding since Noah’s Law took effect in 2016. The good news: most cases have real points of attack, and the strategic moves you make in the first 30 days set the tone for the rest of the case.

How Maryland’s Two-Tier DUI System Works

Maryland uses a two-tier drunk driving statute under Transportation Article Section 21-902. The two charges sound interchangeable but carry meaningfully different penalties.

DUI: Driving Under the Influence of Alcohol

Codified at Section 21-902(a)(1)(i), DUI is the more serious of the two offenses. The Maryland Pattern Jury Instruction tells jurors that DUI requires proof the alcohol “substantially impaired” the driver’s normal coordination. It is a misdemeanor, but the maximum penalty for a first offense is one year in jail and a $1,200 fine, increased to two years and $2,400 for a second offense. The MVA can also assess 12 points and revoke your license.

A breath or blood test result of 0.08 or higher creates a permissive inference that you were under the influence at the time of driving. That inference is not conclusive: you can still argue that the test was inaccurate or that the test reading at the time of testing does not reflect your BAC level at the time you were behind the wheel.

DWI: Driving While Impaired by Alcohol

The lesser offense, driving while impaired (Section 21-902(b)(1)), is also a misdemeanor, but the cap is two months in jail and a $500 fine for a first offense (one year and $500 for a second), with 8 MVA points and a possible license suspension. The difference between DUI and DWI is the degree of impairment the State has to prove. DUI requires substantial impairment of normal coordination; DWI requires only that the driver’s normal coordination has been impaired to some degree. For a side-by-side comparison, see our explainer on DUI vs DWI in Maryland and our follow-up on which is worse, DWI or DUI.

Per Se DUI: The 0.08 Charge

Section 21-902(a)(1)(ii) creates a separate “per se” charge. The State only has to prove two things: that you were driving, and that you submitted to a chemical test with a result of 0.08 or higher at the time of testing. The State does not have to prove actual impairment. Per se DUI is not a lesser-included offense of regular DUI under Maryland appellate caselaw, which means a defendant charged with one cannot be convicted of the other and vice versa. The maximum penalty matches regular DUI: one year and $1,200 for a first offense; two years and $2,400 for a second. Our DUI per se page goes deeper.

Drugs, Prescription Medication, and Combined Impairment

Section 21-902©(1) covers driving while impaired by drugs, or by drugs and alcohol combined, to the extent the driver “cannot drive a vehicle safely.” That language sets a higher bar of impairment than the alcohol-only DWI, but the penalty range mirrors DWI: up to two months and $500 for a first offense, one year and $500 for a second. Section 21-902(d)(1) covers driving while impaired by a controlled dangerous substance the driver is not legally entitled to use, and carries the same penalty structure as alcohol DUI: up to one year and $1,200 for a first offense, two years and $2,400 for a second.

Drug DUI cases tend to involve a Drug Recognition Expert (DRE) and a blood draw rather than a breath test. The blood test for drugs is qualitative, meaning it shows a substance is present but generally cannot tell the jury whether the drug was psychoactive at the time of driving. That gap is one of the central defense angles in drug cases. Legal medication is a frequent source of these charges; we cover that in detail in our DUI prescription drugs post.

2026 Maryland DUI Penalties at a Glance

The penalty grids below come directly from the current text of Maryland Transportation Article Sections 21-902 and 16-205.1, and from the homicide statutes in Title 2 of the Criminal Law Article. For an interactive reference, see our Maryland DUI chart.

Criminal Penalties Under Transportation Article Section 21-902

Offense	Statute	1st Conviction	2nd Conviction
Driving Under the Influence of Alcohol	Section 21-902(a)(1)(i)	1 yr / $1,200	2 yrs / $2,400
Driving Under the Influence Per Se (BAC 0.08+)	Section 21-902(a)(1)(ii)	1 yr / $1,200	2 yrs / $2,400
Driving While Impaired by Alcohol	Section 21-902(b)(1)	2 mo / $500	1 yr / $500
Driving Impaired by Drugs / Drugs + Alcohol	Section 21-902©(1)	2 mo / $500	1 yr / $500
Driving Impaired by Controlled Dangerous Substance	Section 21-902(d)(1)	1 yr / $1,200	2 yrs / $2,400

For (a)(1) and (d)(1) offenses, a prior conviction under any of (a), (b), ©, or (d) (or under Section 8-738 of the Natural Resources Article) within 5 years of the new conviction is treated as a prior. For (b)(1) and ©(1), the cross-subsection prior counts without the 5-year window.

Enhanced Penalties When Transporting a Minor (Under 18)

Offense	Statute	1st Conviction	2nd Conviction
DUI / Per Se DUI w/ Minor	Section 21-902(a)(2)	2 yrs / $2,000	3 yrs / $3,000
DWI w/ Minor	Section 21-902(b)(2)	1 yr / $1,200	2 yrs / $2,400
Drug-Impaired Driving w/ Minor	Section 21-902©(2)	1 yr / $1,200	2 yrs / $2,400
CDS-Impaired Driving w/ Minor	Section 21-902(d)(2)	2 yrs / $2,000	3 yrs / $3,000

See our DUI with child in the car page.

Mandatory Minimum Jail Sentences Under Section 21-902(f)

Trigger	Mandatory Minimum
2nd Section 21-902(a) DUI within 5 years of a prior (a) conviction	5 days
3rd or subsequent Section 21-902(a) within 5 years of a prior (a)	10 days
2nd Section 21-902(d) CDS DUI within 5 years of a prior (d)	5 days
3rd or subsequent Section 21-902(d) within 5 years of a prior (d)	10 days

The mandatory minimums under Section 21-902(f) are not subject to suspension or probation. “Imprisonment” can be served as inpatient treatment or home detention with electronic monitoring for an approved alcohol or drug treatment program. The court must also require a comprehensive abuse assessment and ordered program participation in any second-within-five-years case.

Refusal Enhancement Under Section 21-902(g)

Trigger	Additional Penalty
Conviction under Section 21-902 with finding beyond a reasonable doubt that the defendant knowingly refused the chemical test	Up to 2 mo additional jail / $500 additional fine

The State must serve notice of the alleged refusal on the defendant or counsel before acceptance of a plea, or at least 15 days before trial in Circuit Court (5 days in District Court). The penalty under (g) stacks on top of the underlying Section 21-902 violation.

Habitual Offender Penalties

Trigger	Statute	Maximum Penalty
Violating Section 21-902(a), (b), ©, or (d) with 2 prior convictions under any of those subsections	Section 21-902(h)	5 yrs / $5,000 (misdemeanor)
Violating Section 21-902(a), (b), ©, or (d) with 3 or more priors under those subsections, or with a prior conviction under Crim. Law Sections 2-209, 2-503, 2-504, 2-505, 2-506, or 3-211	Section 21-902(i)	10 yrs / $10,000 (misdemeanor)

For repeat-offender exposure, see our pages on second DUI, 4th DUI, subsequent offender DUI, and 21-902(h) repeat DUI.

MVA Administrative Penalties Under Section 16-205.1

Test Result	1st Offense	2nd or Subsequent
0.08 to 0.14 (failed test)	180-day suspension	180-day suspension
0.15 or more (failed test)	180-day suspension	270-day suspension
Test refusal	270-day suspension	2-year suspension
Failed test, 0.08 to 0.14, with fatal accident	6-month suspension	1-year suspension
Failed test, 0.15 or more, with fatal accident	1-year suspension	Revocation

The administrative case under Section 16-205.1 runs separately from any criminal case. The hearing request fee is $150, refundable if the MVA takes no action. See our MVA hearings page.

Ignition Interlock Program Lengths Under Section 16-205.1(g)

Test Result	Interlock Period (in lieu of suspension)
0.08 to 0.14	180 days
0.15 or more	1 year
Test refusal	1 year

Vehicular Homicide Penalties

Offense	Statute	1st Conviction	With Qualifying Prior
Manslaughter by Vehicle (gross negligence)	Crim. Law Section 2-209	10 yrs / $5,000	15 yrs / $10,000
Criminally Negligent Manslaughter by Vehicle	Crim. Law Section 2-210	3 yrs / $5,000	5 yrs / $10,000
Homicide While Under the Influence / Per Se	Crim. Law Section 2-503	5 yrs / $5,000	10 yrs / $10,000
Homicide While Impaired by Alcohol	Crim. Law Section 2-504	3 yrs / $5,000	5 yrs / $10,000
Homicide While Impaired by Drugs	Crim. Law Section 2-505	3 yrs / $5,000	5 yrs / $10,000

Qualifying priors for the enhanced penalty include any conviction under Crim. Law Sections 2-209, 2-210, 2-503, 2-504, 2-505, 2-506, or 3-211, or under Section 21-902. See our DUI manslaughter post.

The Roadside Stop: What Police Actually Do

Almost every Maryland DUI starts the same way. An officer makes a traffic stop based on observed driving (weaving, speeding, equipment violations, running a red light, hitting a checkpoint), approaches the vehicle, and starts looking for the standard list of impairment cues: odor of alcohol, bloodshot or watery eyes, slurred or thick speech, fumbling with documents, an open container, an admission of drinking. If those cues build up, the officer asks the driver to step out for field sobriety tests. We break down the full sequence at our DUI stop page and our explainer on what happens at a DUI stop.

Field Sobriety Tests Are Voluntary

The three Standardized Field Sobriety Tests (SFSTs) approved by the National Highway Traffic Safety Administration are the Horizontal Gaze Nystagmus (HGN), the Walk and Turn, and the One Leg Stand. Maryland appellate cases have placed limits on how the HGN test results may be used; among other things, HGN results may not be used to establish a specific blood alcohol level, only as evidence the driver may have consumed alcohol. The State must show the officer was properly trained and that the test was administered properly.

In Maryland, field sobriety tests are voluntary at the roadside. Refusing them does not trigger an automatic license suspension the way refusing a breath test does. Officers will often phrase the request in a way that sounds mandatory, but it is not. We cover the practical decision in our posts on whether you should do field sobriety tests and the science behind field sobriety testing.

The Preliminary Breath Test (PBT)

After the SFSTs, the officer may request a preliminary breath test on a portable handheld device. The PBT is different from the evidentiary breath test administered later at the station. PBT results have limited evidentiary value at trial and are used primarily to support probable cause for arrest. The post-arrest breath test, taken on the Intoximeter EC/IR II at the station within two hours of apprehension, is the test that produces the BAC number used at trial and at the MVA. We compare the two devices at our PBT vs breathalyzer post.

Probable Cause for Arrest

To make a DUI arrest, the officer needs probable cause. Maryland courts review the totality of the circumstances: the driving, the smell of alcohol, the driver’s appearance and speech, the field sobriety test performance, the PBT result, statements from the driver, and any admissions. A weak link anywhere in this chain (an unjustified stop, poorly performed field sobriety tests, a problematic PBT) can be a basis for a motion to suppress. Our probable cause and DUI post lays out the standard.

The DR-15 Advisement and the Implied Consent Statute

After arrest, the officer is required to “fully advise” you of the consequences of taking or refusing the chemical test. Those consequences are spelled out on the DR-15 form, and the order of suspension and temporary license are issued on the four-page DR-15A. The officer must explain the administrative penalties for failing or refusing the test, including the fact that drivers with results of 0.15 or higher and drivers who refuse are ineligible for any restricted license other than the ignition interlock. The officer also has to advise you of the potential enhanced criminal penalty under Section 21-902(g) (up to two months additional incarceration and a $500 additional fine) for knowingly refusing the test.

You can consult with a lawyer if you ask, so long as the consultation does not interfere with the testing process. The breath test technician is required to administer the test within two hours of apprehension, so a request for counsel cannot be used to delay indefinitely. Most DUI stops are required to use a breath test unless: the driver is taken to a medical facility for treatment of injuries; the driver is unconscious or otherwise incapable of refusing; or the test equipment is unavailable. If the officer has reasonable grounds to believe the driver was involved in an accident causing death or life-threatening injury, the officer is empowered to collect both breath and blood. Our post on hospital blood draws in DUI cases covers what happens after an accident.

For the practical decision-making side of test consent, see our posts on whether to provide a breath sample in Maryland and the consequences of refusing a breathalyzer.

The Two-Track System: Criminal Court and MVA

A Maryland DUI runs on two tracks at the same time, and they operate independently of each other.

Track One: The Criminal Case

The criminal case starts with a citation or formal charging document. Most first-offense DUI cases land in District Court, where there is no jury and a single judge hears the case. Defendants have the right to demand a jury trial, which removes the case to Circuit Court. Demanding a jury can be strategic for several reasons; we cover the analysis at our DUI jury trial post.

Track Two: The MVA Case

The administrative case opens automatically when the officer sends a sworn report to the MVA within 72 hours of arrest. The MVA does not care what happens in criminal court. A dismissal in District Court does not undo an MVA suspension, and a not-guilty verdict does not refund a refusal suspension. The MVA case is its own beast, with its own hearings, evidence rules, and remedies through the Office of Administrative Hearings (OAH). Our overview is at the MVA hearings page.

This dual-track structure is why missing the MVA hearing deadline can be more consequential than people realize. You can win the criminal case and still lose your license through inaction at the MVA.

Aggravating Factors and Repeat Offenses

Several factors push penalties well past the base grid.

Mandatory Minimums for Repeat DUI

Under Section 21-902(f)(2), if you are convicted of violating Section 21-902(a) within five years of a prior (a) conviction, the court must impose a mandatory minimum of five days in jail. A third or subsequent conviction within five years carries a 10-day mandatory minimum. Section 21-902(f)(3) imposes the same mandatory minimums for repeat (d) CDS DUI offenses. The mandatory minimums under (f) are not subject to suspension or probation, though “imprisonment” can be served as inpatient treatment or home detention with electronic monitoring for an approved program.

The State has to give written notice of any enhanced sentence. For permissible enhancements, the deadline is five days before trial in District Court and 15 days before trial in Circuit Court. For mandatory enhancements, notice must be given five days before sentencing in District Court and 15 days before in Circuit Court.

Penalties When a Minor Was in the Car

Driving under the influence or impaired with someone under 18 in the vehicle is a separate enhanced offense under Sections 21-902(a)(2), (b)(2), ©(2), and (d)(2). The maximum penalty for a first conviction under Section 21-902(a)(2) or (d)(2) is two years and $2,000; a second conviction maxes at three years and $3,000. Under Section 21-902(b)(2) or ©(2), the first offense maxes at one year and $1,200, with a second going up to two years and $2,400. Our DUI with child in the car page goes deeper.

Habitual Offender Provisions Under (h) and (i)

When a defendant has two prior convictions under any combination of Section 21-902(a), (b), ©, or (d), Section 21-902(h) makes the next violation punishable by up to five years and $5,000. When a defendant has three or more such prior convictions, or has a prior conviction under Crim. Law Sections 2-209, 2-503, 2-504, 2-505, 2-506, or 3-211, Section 21-902(i) makes the next violation punishable by up to 10 years and $10,000.

High BAC: The 0.15 Threshold

A test reading of 0.15 or higher is treated as an aggravating factor. While the criminal charge itself is still the same Section 21-902(a) DUI, the administrative penalties at the MVA are more severe, and prosecutors often use a high BAC as evidence of extreme impairment when arguing for jail time at sentencing. Our high BAC DUI post covers the strategy in those cases.

Vehicular Homicide and DUI Manslaughter

When a death is involved, the charges shift from Title 21 of the Transportation Article to Title 2 of the Criminal Law Article. Under Crim. Law Section 2-503, homicide by motor vehicle while under the influence of alcohol or under the influence per se is a felony with a five-year cap and a $5,000 fine, increased to 10 years and $10,000 for repeat offenders. Section 2-504 covers homicide by motor vehicle while impaired by alcohol (3 years and $5,000; 5 years and $10,000 for repeat offenders). Section 2-505 covers homicide while impaired by drugs (same penalty range). Manslaughter by automobile under Crim. Law Section 2-209 covers grossly negligent driving causing death and carries up to 10 years and $5,000 (15 years and $10,000 for repeat offenders). Our DUI manslaughter post explains how these get charged and the relationship between the various titles. For non-fatal accidents, our DUI accident case post covers exposure when injuries are involved.

The MVA Administrative Track and Noah’s Law

Maryland’s implied consent statute, Section 16-205.1, sets the administrative penalty grid that the MVA imposes through OAH. The penalties were significantly increased under Noah’s Law, named after Montgomery County Police Officer Noah Leotta who was killed by a drunk driver while at roadside on a DUI stop. Noah’s Law took effect October 1, 2016. The current 2026 penalty structure under Section 16-205.1 is:

• Test result of 0.08 or more but less than 0.15: 180-day suspension on a first offense, 180 days on a second or subsequent offense. A modification or restricted license may be available for work, alcohol education, school, or health care purposes for the licensee or an immediate family member.
• Test result of 0.15 or more: 180-day suspension on a first offense, 270 days on a second or subsequent offense. The only restricted license available is one requiring a one-year ignition interlock.
• Test refusal: 270-day suspension on a first offense, two years on a second or subsequent offense. The driver may elect the one-year ignition interlock program in lieu of serving the suspension.

If a fatal accident is involved, the suspension lengths are increased: six months for a first offense at 0.08 to 0.14 (one year for second or subsequent), and one year for a first offense at 0.15 or higher (revocation for second or subsequent).

The 30-Day MVA Hearing Window

The DR-15A you received at the roadside is a four-page document printed on two pages, front and back. It contains the order of suspension, your temporary driver’s license, the officer’s statement of reasonable grounds, information on the ignition interlock program, a form to waive the hearing and enroll in the interlock, and the form to request a hearing.

For Maryland licensees, the temporary license is good for 45 days. The actual suspension takes effect on the 46th day after arrest unless you act. To preserve your right to a hearing, you have 30 days from the date of issuance of the order of suspension to either:

1. Request a hearing (with a $150 check made payable to the Maryland State Treasurer, refunded if no action is taken), or
2. Waive the hearing and elect the ignition interlock program (if eligible).

This deadline is enforced strictly. Maryland appellate caselaw treats the 30-day requirement as construed strictly against the driver. The only exception in the regulations is for a person who is incapacitated to the point of being unable to file. Miss it and the maximum suspension goes into effect automatically.

For drivers who request a hearing within the first 10 days, the MVA is required to extend the temporary license until the hearing date. The MVA generally extends anyway if the request is made within 30 days, but the 10-day window is the only one with a guarantee.

Out-of-state licensees do not have their physical license seized at the roadside, but they should still file the hearing request within 30 days. They can continue to drive in Maryland on their out-of-state license pending the hearing.

Our MVA hearings page and our Maryland DUI administrative hearings post cover the hearing process in detail.

Ignition Interlock: Eligibility, Rules, and Failures

The ignition interlock is a small breath-testing device wired into the vehicle’s electronic system, usually mounted in the center console area near the driver. The car will not start unless the driver provides an alcohol-free breath sample. While driving, the device prompts for retests, and if a sample is not provided or registers above the threshold, the violation is recorded. Service providers download the data on a monthly cycle.

Who Is Eligible

Under Section 16-205.1(g):

• Drivers with test results of 0.15 or more or who refused the test can modify the suspension by participating in the program for one year.
• Drivers with results of 0.08 to 0.14 may elect to enroll for 180 days in lieu of requesting a hearing or after the hearing.
• Out-of-state licensees are not currently eligible for the program. Some Administrative Law Judges will, in their discretion, grant a request to allow an out-of-state licensee to drive with an interlock in Maryland in lieu of serving the suspension, primarily for nearby D.C., Virginia, West Virginia, Pennsylvania, and Delaware drivers with a legitimate work need.

Failures and Termination

The MVA deems a driver to have failed the program if they have violations in a total of four reporting periods (a reporting period is up to 30 days). Violations under the COMAR regulations include:

• Test readings above 0.025 BrAC, unless a retest within five minutes shows below 0.026.
• “Rolling refusals,” where the driver fails to provide a sample when prompted.
• Failure to operate the vehicle at least 50 times during a reporting period.
• Missing the monthly service appointment.
• Allowing another person to blow into the device.
• Failing to abide by the participant agreement.

If the program is terminated, the driver does not get credit for the time served, and the original suspension is imposed after a hearing opportunity. Our pages on ignition interlock violations, removal from ignition interlock, ignition interlock removal, and the ignition interlock violation lawyer page cover the issues that come up.

Commercial Driver’s License (CDL) DUI

Transportation Article Section 16-812 sets the CDL disqualification framework, and the consequences for CDL holders are dramatically harsher than for non-commercial drivers.

Under Section 16-812(a), the MVA must disqualify a CDL for one year if the individual is convicted of any of the following while driving a commercial vehicle:

• A violation of Section 21-902 (any subsection)
• A substantially similar federal or out-of-state DUI offense
• Leaving the scene of an accident
• A felony other than a controlled-substance-distribution felony
• Refusing to undergo testing under Section 16-205.1, federal law, or another state’s law while driving a commercial vehicle
• Driving a commercial vehicle with a BAC of 0.04 or more

Under Section 16-812(b), if any of the offenses in (a) occurred while transporting hazardous material required to be placarded, the disqualification is three years instead of one.

Under Section 16-812©, the MVA must disqualify the CDL for life for two or more violations of (a) or (b) arising from separate incidents. Under Section 16-812(d), the MVA may reduce a lifetime disqualification under regulations consistent with federal law (typically allowing reinstatement after 10 years).

Under Section 16-812(e), the MVA must disqualify the CDL for life if the driver is convicted of using a motor vehicle in the commission of a controlled-substance-manufacture or distribution felony. This disqualification is not reducible.

Even a non-commercial DUI in a personal vehicle can result in CDL disqualification, because Section 16-205.1 itself provides that a CDL is disqualified for one year (or for life on a second offense) if the holder refuses a test or has a BAC over the standard threshold while operating a non-commercial vehicle. For drivers whose livelihoods depend on the CDL, a charge that looks ordinary on the criminal side can be career-ending. See our pages on CDL DUI in Maryland and commercial license DUI.

Drivers Under 21

Under Transportation Article Section 16-113(b)(1), the MVA imposes an automatic alcohol restriction on every licensee under 21 that prohibits the licensee from driving or attempting to drive while having any alcohol in the blood. The restriction expires when the licensee turns 21. A breath or blood test of 0.02 or higher is prima facie evidence of alcohol in the blood under Cts. & Jud. Proc. Section 10-307(e), and prima facie evidence of a violation of the alcohol restriction under Section 10-307(f).

Under Section 16-113(b)(4), an under-21 licensee who is convicted of a violation of Section 21-902(a), (b), or © may be required to participate in the Ignition Interlock System Program for up to three years in order to retain the license.

Under Section 16-113(g)(1), if any licensee (regardless of age) is convicted within five years of two or more violations under Section 21-902(a), (b), or ©, the MVA must impose a three-year alcohol restriction prohibiting the individual from driving with any alcohol in the blood, often coupled with the interlock requirement under Section 16-404.1.

Under Section 16-113(f), the MVA may suspend or revoke a restricted or provisional license after receiving satisfactory evidence of any violation, with hearing rights under Subtitle 2.

The under-21 restriction case is initiated separately from any Section 16-205.1 case, which means an under-21 driver charged with DUI can face two MVA actions running on different timelines. Our pages on under-21 DUI, under-18 DUI, and DUI ages 18 to 20 cover the full picture.

The Court Process from Arrest to Disposition

After arrest, the typical procedural sequence in Maryland DUI cases looks like this:

1. Initial appearance / commissioner review. Within 24 hours of arrest, the defendant appears before a District Court Commissioner who sets initial conditions of release. Most first-offense DUIs result in release on personal recognizance or low bail. Our bail for DUI in Maryland post covers the bail analysis.
2. Pre-trial discovery. Defense counsel requests the police reports, body cam, dash cam, breath test maintenance and calibration records, the breath operator’s certification, and any video from the breath room.
3. Motions practice. Defense counsel may file motions to suppress (challenging the stop, arrest, or chemical test), motions in limine, and discovery motions.
4. Trial or plea. The defendant has the right to a District Court bench trial or, if a jury demand is made, a Circuit Court jury trial. Our post on what happens at a DUI trial walks through the trial mechanics.
5. Sentencing. If convicted or after a guilty plea, the court imposes sentence. Probation is common for first offenders without aggravating factors.

Missing a court date is its own problem, with bench warrants and bond consequences. Our missed DUI court date post explains what to do.

Probation Before Judgment (PBJ)

A judge can grant probation before judgment under Crim. Proc. Section 6-220, which prevents the entry of a formal conviction on the criminal record. PBJ is a discretionary disposition; you do not have a right to it.

Important caveats:

• A PBJ does not undo or reduce the MVA administrative suspension under Section 16-205.1.
• A PBJ counts as a “prior conviction” for purposes of subsequent-offender sentencing under Section 21-902 if you pick up another DUI.
• A PBJ becomes eligible for expungement after specific waiting periods.
• A judge cannot grant PBJ in DUI cases where the defendant has had a prior DUI, DWI, or controlled-substance DUI within the previous 10 years.

Our posts on PBJ for Maryland DUI and DUI PBJ in Maryland cover when PBJ is realistically on the table and how to position the case for it.

Common Defense Strategies

Maryland DUI cases have real, repeatable points of attack. The most effective defenses depend on the specific facts, but the recurring themes include:

• Challenging the stop. If the officer lacked reasonable suspicion to make the traffic stop, everything that follows can be suppressed under the Fourth Amendment.
• Challenging probable cause for arrest. Weak field sobriety performance, ambiguous PBT results, and limited driving observations can together fail to establish probable cause.
• Challenging the breath test. Issues with the Intoximeter EC/IR II’s calibration logs, the operator’s certification, the 20-minute observation period, the two-hour testing window, the chain of custody, and the source code can all undermine a breath result. Our post on challenging breath results covers the technical attacks.
• Rising BAC defense. If alcohol was still being absorbed at the time of driving, the test reading at the station may overstate the BAC at the time of the offense. Federal cases like United States v. Nestor and the Maryland appellate analysis of relation-back evidence support this defense in the right factual posture.
• Medical conditions. GERD, diabetes, and certain mouth conditions can affect breath testing.
• Field sobriety test administration errors. Officers regularly deviate from NHTSA-validated administration protocols, undermining the evidentiary value of the tests.
• Improper DR-15 advisement. If the officer failed to fully advise the driver of the consequences of failing or refusing the test, the suspension itself can be challenged at the MVA.

Less Obvious Scenarios: Bikes, Boats, Parked Cars, and Private Property

Maryland’s DUI statute reaches further than most drivers realize.

• Sleeping in your car. A driver can be convicted of DUI even without driving if a court finds “actual physical control” of the vehicle. The Maryland test looks at whether the driver had the apparent ability and present intent to operate the vehicle. The keys, the location of the driver, whether the engine was running, and whether the vehicle was in a position to be driven all factor in. Our posts on DUI sleeping in car and DUI while parked cover the actual physical control analysis.
• Private property. Maryland’s DUI statute applies on highways and on any property used by the public for vehicular travel. Private property can still be DUI territory. See our DUI on private property post.
• Boats. Maryland’s boating-while-impaired statute mirrors the road version. Our DUI on a boat post lays it out.
• Bicycles. Maryland courts have addressed whether bicycles fall under the DUI statute. See DUI on a bike.
• Horses. Yes, this comes up. See DUI on a horse.
• Test result under 0.08. A test below 0.08 does not end the case; it just removes the per se inference. The State can still convict on DUI or DWI based on other evidence of impairment. Our post on DUI under the limit explains.

Out-of-State DUI

If you have a Maryland license and are charged with DUI in another state, the conviction will be reported back to the Maryland MVA under the Driver License Compact, and Maryland will impose its own administrative consequences. If you have an out-of-state license and are charged in Maryland, the Maryland charge will be reported back to your home state. Our out-of-state DUI post covers reciprocity and the practical complications.

Collateral Consequences Beyond the Criminal Sentence

The criminal sentence and license suspension are usually only part of the cost.

• Insurance. Auto insurance premiums increase significantly after a DUI conviction, and many insurers cancel coverage outright. Maryland may require an SR-22 filing.
• Employment and security clearances. A DUI conviction can affect employment, particularly in regulated industries, government contracting, and positions requiring a security clearance. See our post on Maryland DUI and security clearances.
• Professional licenses. Many Maryland professional boards (medical, nursing, legal, real estate, teaching) require self-reporting of arrests and convictions. See DUI with a professional license and our DUI professional licenses page.
• Immigration. Non-citizens facing DUI charges should consult an immigration attorney; certain dispositions can have immigration consequences.

Expungement and Long-Term Record

A conviction for DUI or DWI in Maryland is not generally eligible for expungement. PBJ dispositions are eligible for expungement after the waiting period prescribed by Crim. Proc. Section 10-105, with specific exceptions and waiting periods that apply to alcohol-related offenses. Our posts on DUI expungement in Maryland, how long a DUI stays on record, and how long a DUI is on my record in Maryland cover what you can and cannot expunge.

A DUI conviction also stays on the MVA driving record for an extended period and counts for points purposes and for subsequent-offender sentencing for years.

What This Looks Like in Practice

Most Maryland DUI cases begin with the same opening sequence: roadside encounter, field sobriety, breath test (or refusal), DR-15A, and the 30-day deadline. From there, cases diverge based on the test result, prior history, whether anyone was injured, whether a minor was in the vehicle, and how cleanly the stop and arrest were conducted. The strategic decisions all happen on tight clocks: whether to take the breath test (immediately), whether to request an MVA hearing or waive into the interlock (within 30 days), whether to demand a jury trial (before the District Court trial date), whether to seek PBJ, and how to handle pleas.

If you are facing a DUI charge in Maryland, the move worth making early is locking down the MVA hearing request before that 30-day window closes, then working through the criminal case with the test results, body cam, and DR-15 advisement in hand. Our overview at what happens when you get a Maryland DUI, the DUI guide, and Maryland DUI: what to expect lay out the full timeline.

FAQs

Q: What is the legal BAC limit in Maryland?

A: 0.08. A test result of 0.08 or higher creates a permissive inference under per se DUI that you were under the influence at the time of driving. A reading of 0.15 or higher carries enhanced administrative penalties under Section 16-205.1. CDL holders are subject to a 0.04 limit when operating a commercial vehicle under Section 16-812.

Q: What is the difference between DUI and DWI in Maryland?

A: DUI is the more serious offense and requires proof that alcohol substantially impaired your normal coordination. DWI requires a lesser degree of impairment. DUI carries up to one year and a $1,200 fine for a first offense (12 MVA points); DWI carries up to two months and $500 (8 points). Maryland’s two-tier system is based on degree of impairment, not on a specific BAC range. The full comparison is on our DUI vs DWI page.

Q: How long do I have to request an MVA hearing?

A: 30 days from the issuance of the order of suspension. Miss it, and the maximum administrative suspension goes into effect on the 46th day after arrest, when the temporary license expires. Out-of-state licensees should still file within 30 days even though their physical license is not seized.

Q: What happens if I refuse the breath test in Maryland?

A: A first refusal triggers a 270-day administrative suspension, and a second or subsequent refusal triggers a two-year suspension. You can elect the one-year ignition interlock program in lieu of the suspension. Refusal can also support an enhanced criminal penalty of up to two months additional jail and a $500 additional fine under Section 21-902(g), and it is admissible against you at trial as evidence of consciousness of guilt.

Q: Can I get a DUI in Maryland if the car was parked or I was just sleeping?

A: Yes, in some circumstances. Maryland uses an “actual physical control” analysis that looks at whether you had the apparent ability and present intent to operate the vehicle. Where the keys are, whether the engine is running, where you are sitting, and whether the vehicle is in a position to be driven all matter. Our DUI sleeping in car post and DUI while parked post break down the factors.

Q: Will a DUI conviction stay on my record?

A: A criminal conviction stays on your record permanently unless expunged. DUI convictions in Maryland are not generally expungeable, though PBJ dispositions can be expunged after a statutory waiting period. The MVA driving record retains the conviction for an extended period and uses it for points and subsequent-offender purposes. Our DUI expungement post covers what is and is not expungeable.

Q: Do I need a lawyer for a first DUI?

A: A first DUI carries up to one year in jail, a $1,200 fine, an MVA suspension, 12 points, and significant insurance and employment consequences. The strategic decisions, including whether to request a hearing, install an interlock, demand a jury trial, and seek PBJ, all happen on tight deadlines and are difficult to undo after the fact. Our first-time DUI FAQ and post on whether you need a lawyer for a first DUI cover the early decisions.

Q: How much does a DUI lawyer cost in Maryland?

A: Costs vary based on the complexity of the case, whether a jury trial is demanded, whether expert witnesses are needed, and whether MVA hearings are involved. Most Maryland DUI lawyers charge a flat fee for the criminal case and a separate flat fee for the MVA hearing. Contingency fees are prohibited in criminal cases under the Rules of Professional Conduct. Our how much will a DUI lawyer cost post covers typical fee structures.

Q: Can a DUI charge be reduced to reckless or negligent driving?

A: It depends on the strength of the State’s case and the prosecutor’s policy. Reductions are more common where the breath test is suppressible, where the field sobriety performance was strong, or where the BAC was close to 0.08. Our reckless vs negligent driving DUI post covers the difference between the typical reduction options.

Q: What if I have a Maryland DUI and a CDL?

A: Under Section 16-812, a DUI conviction can trigger a one-year CDL disqualification on the first offense and a lifetime disqualification on the second, even if the DUI happened in a personal vehicle. CDL holders facing DUI charges have to think about both the underlying charge and the federal-state disqualification rules. See our CDL DUI post.
