Can you refuse a field sobriety test in Maryland?

On Behalf of | Nov 4, 2025 | Drunk Driving

If a police officer stops you on suspicion of drunk or drugged driving in Maryland, they may ask you to perform field sobriety tests. Many drivers wonder if they have the right to refuse these tests. Understanding your rights and the consequences of refusal can help you make informed decisions during a traffic stop.

What field sobriety tests are and how they work 

Field sobriety tests help officers look for signs of impairment. These include the walk-and-turn, one-leg stand, and horizontal gaze nystagmus tests. Officers use them to gather evidence before making an arrest. However, these tests are subjective and depend on the officer’s interpretation, which can be affected by conditions like lighting, weather, or medical issues.

Your right to refuse field sobriety tests 

In Maryland, you can legally refuse field sobriety tests. There is no penalty under state law for refusing to perform them. However, refusal may not prevent arrest if the officer believes there is enough evidence of impairment. The officer might rely on other signs such as your speech, odor of alcohol, or driving behavior.

How refusal affects your DUI case 

Refusing a field sobriety test might limit the evidence available against you, but it can also raise suspicion. Prosecutors may argue that you refused because you knew you were driving while impaired. Still, without the test results, it may be harder for the state to prove impairment beyond a reasonable doubt. Each case depends on the circumstances and other evidence gathered during the stop.

Refusing a field sobriety test is not the same as refusing a chemical test, such as a breath or blood test. Under Maryland’s implied consent law, refusing a chemical test leads to automatic license suspension and other penalties. Knowing this distinction is important when deciding how to respond during a stop.
