Failure to Control Speed to Avoid Collision Lawyer (Md. Transp. § 21-801)
A rear-end collision on the Beltway. A wet-weather crash on Route 50. A parking-lot tap in Bowie. The trooper hands you a yellow citation that reads "failure to control speed to avoid collision." That citation is Md. Transp. § 21-801, the Maryland Transportation Article's Basic Rule on speed.
This is one of the most common citations written in Maryland traffic court. It is also one of the most common to fight, because it carries MVA points and an insurance hit, and the State's evidence is almost always circumstantial.
What the statute says
Section 21-801 of the Maryland Transportation Article is titled "Basic Rule." It reads in part:
"(a) A person may not drive a vehicle on a highway at a speed that, with regard to the actual and potential dangers existing, is more than that which is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing."
The collision provision is at subsection (b):
"(b) Consistent with subsection (a) of this section, the driver of every vehicle on a highway shall, as required by the conditions of traffic … (2) Control the speed of the vehicle as necessary to avoid colliding with any person, vehicle, or other conveyance on or entering the highway."
The citation does not require that you exceeded the posted limit. It requires only that your speed was too fast to stop before the impact.
Why it gets written after almost every fender-bender
Officers rarely see a crash happen. They arrive after the fact, take statements, and have to pick a charge. Section 21-801(b)(2) lets them write a ticket without proving your actual speed. The crash itself is the evidence. If you hit the car in front of you, the inference the State wants is that you couldn't stop in time, so your speed was too fast for the conditions.

What the citation costs
The citation is payable. You can mail in the fine and skip court. Doing that has three costs:
- 3 MVA points
- An insurance premium hit at renewal
- A conviction on the abstract that any plaintiff's lawyer can use against you in a civil suit
If the crash injured someone, the personal injury lawyer for the other driver may cite the conviction as evidence of negligence.

How we defend these cases
Most § 21-801 cases are won at trial, not at the citation stage. The State has to put on a witness who can describe the driving, prove your speed was excessive for the conditions, and prove no defense applies. The State rarely has all three.
Defense angles we work in every case:
- Sudden emergency. Maryland recognizes the sudden emergency doctrine. If a deer ran out, a child stepped off the curb, or the lead driver slammed the brakes for no traffic reason, the conditions that "existed" at the moment of the crash were not normal driving conditions.
- Mechanical failure. Brake fade, a blown tire, or a defect you did not know about can negate the element that your speed was unreasonable.
- Lead driver fault. Section 21-801 looks at your duty. A driver who cut in late, reversed, or stopped in a travel lane creates conditions your reasonable speed could not anticipate.
- The other driver did not show up. The State has to put a witness on the stand. In a property-only fender-bender, the other driver often skips court. Without that witness, the State's case usually collapses.
- No driving witness. If the trooper did not see the driving and the other driver did not testify, the State cannot prove the elements.

When you should call us
You should call a lawyer about a § 21-801 citation if:
- The crash involved an injury
- You hold a CDL or drive for work
- Your insurance is on a non-renewal track
- The officer wrote § 21-801 alongside a serious traffic charge like negligent or reckless driving
- You want to keep a clean abstract for any reason
For a clean-record outcome, the typical path is a request for trial date, a defense lawyer at the hearing, and either a verdict in your favor or a probation before judgment (PBJ) disposition. PBJ keeps the conviction off the abstract and out of the insurer's underwriting decision.
Prince George's County practice notes
PG County hears § 21-801 cases at the District Court in Hyattsville and Upper Marlboro. The MSP barracks in College Park and Forestville write most of the citations on the I-95 and Beltway corridors. PG District Court is open to PBJ for first-time defendants with clean records, with the right presentation.
