What is Implied Consent in Maryland DUI Cases?

Under Maryland law, every driver on the state’s roads has given implied consent to submit to chemical testing (e.g., breath or blood tests) if suspected of driving under the influence (DUI) or driving while impaired (DWI). This means that by holding a Maryland driver’s license or operating a vehicle in the state, you agree to these tests when lawfully requested by law enforcement.

The legal foundation for implied consent is found in the Maryland Transportation Article Section 16-205.1, which outlines the consequences for refusing a chemical test.

When Does Implied Consent Apply?

Implied consent is triggered when:

• You are stopped by law enforcement with reasonable grounds to believe you are driving under the influence.
• You are arrested for DUI/DWI.
• A Breath or Blood Test is Requested by the Officer.

The officer must advise you of the consequences of refusing the test or failing it, typically by providing, reading, or playing the audio of a DR-15 Advice of Rights form.

You must then sign accepting or refusing the test.

Consequences of Refusing a Chemical Test

Refusing a breathalyzer or blood test in Maryland comes with significant penalties:

1. Administrative Penalties

   • First Refusal: 270-day license suspension.
   • Second Refusal: 2-year suspension.

2. Ignition Interlock Requirement

   • You may be required to install an ignition interlock device on your vehicle for a year to regain driving privileges.

3. Evidentiary Impact

   • Refusal can be introduced as evidence in court, potentially implying guilt.

Does Refusal Mean No Evidence?

Not necessarily. If you refuse a chemical test, law enforcement may rely on other evidence to build their case, such as:

• Field sobriety tests.
• Officer observations (e.g., slurred speech, odor of alcohol).
• Witness testimony.

Defenses Against Implied Consent Violations

1. Challenging Probable Cause

   • If the officer lacked reasonable suspicion to stop you, the test request could be deemed invalid.

2. Improper Advisement

   • If the officer failed to properly advise you of the consequences of refusal, your refusal might not hold up in court.

3. Medical Exceptions

   • Certain medical conditions can render breath or blood tests inaccurate or impossible.

A: If the officer did not properly advise you, the refusal might be inadmissible in court and your license suspension may be challenged in an administrative hearing.
