What must a driver do if they refuse to take a test for drugs and alcohol?

When a driver refuses to take a test for drugs and alcohol, they must surrender their driver's license. This is in accordance with Maryland's implied consent laws, which state that by operating a vehicle, a driver implicitly agrees to submit to chemical testing when requested by law enforcement. If a driver refuses the test, they face automatic consequences, including license suspension or revocation. This measure is intended to encourage compliance with testing regulations, as driving under the influence poses significant risks to public safety.

The other options do not align with the legal requirements and consequences established by the law in such situations. While filing complaints or challenging police actions in court may be appropriate in different contexts, they do not address the immediate requirement related to testing refusal. Similarly, paying a fine immediately may not be a consequence directly linked to the refusal, and the act of challenging the police officer does not negate the obligation to comply with testing.
