Implied Consent and Drunk Driving in Maryland

Compelling a Breath or Blood Test Without a Warrant

Implied Consent and Drunk Driving in MarylandAs a general rule, you cannot be subjected to a search or seizure without a warrant, as set forth in the 4th Amendment to the U.S. Constitution. There are, however, certain situations where a police officer may do just that, provided there are reasonable grounds to believe that a law has been or is being violated. One such situation occurs when a police officer reasonably suspects a person of driving while impaired by alcohol or drugs.

Under the implied consent laws in force in Maryland, when you operate a motor vehicle on public roads or private property used by the public, you agree to submit to a drug or alcohol test in the event you’re stopped for suspicion of driving under the influence of drugs or alcohol. There is no requirement that you agree, verbally or in writing, to take the test. The officer cannot compel you to take a blood or breath test, but if you do, your license can be suspended for up to 270 days, and you can face fines, as well as incarceration. Furthermore, unlike many other states, if you refuse to take the test, that refusal can be introduced as evidence at your criminal trial.
