We Fight to Protect Your Rights

If police stop you for suspected drunk driving in Maryland, they may request a breath or blood test. That request activates the state’s implied consent law, which affects your driving privileges even before any court case begins. Knowing how refusals work helps you understand the immediate and long-term consequences of that decision.
What implied consent means in Maryland
Maryland law treats the act of driving on public roads as an agreement to submit to chemical testing after a lawful DUI arrest. An officer must have reasonable grounds to believe alcohol or drugs impaired your driving and must place you under arrest before requesting a test. These legal requirements matter because failure to follow them can affect administrative penalties.
What happens if you refuse testing
Refusing a chemical test triggers administrative sanctions through the Maryland Motor Vehicle Administration rather than the criminal court. A first refusal may result in a 270-day license suspension, while a second or subsequent refusal may lead to a two-year suspension. These penalties apply regardless of how the criminal DUI charge later resolves.
How refusals affect DUI cases
A refusal does not stop a DUI prosecution, and the state may rely on other evidence such as driving behavior, field sobriety tests, and officer observations. Courts may also consider the fact that you refused testing when evaluating the case. As a result, refusals often shift attention to whether police followed proper procedures during the stop and arrest.
Challenging a suspension after refusal
After a refusal, you have a limited period, typically ten days, to request a hearing with the Motor Vehicle Administration. That hearing focuses on whether the officer had reasonable grounds, made a lawful arrest, and properly requested the test. Missing the deadline generally results in automatic suspension without further review.
Implied consent refusals can disrupt work schedules, family responsibilities, and daily transportation needs due to extended license suspensions. These consequences arise quickly and operate separately from any criminal penalties. Understanding how Maryland law handles refusals allows you to better anticipate what follows a roadside decision.
