Under Maryland’s implied-consent rule, a person is deemed to have consented to an alcohol or drug test by:
Correct answer: A – Driving or attempting to drive on a highway or private property used by the public
The rule applies when a person drives or attempts to drive and is detained on suspicion of an alcohol- or drug-related driving violation. Depending on the circumstances, testing may involve breath or blood. Refusing a requested test generally results in a 270-day suspension for a first refusal and a two-year suspension for a second or subsequent refusal.
