What is the blood alcohol concentration (BAC) threshold for driving under the influence (DUI) in Maryland?

The blood alcohol concentration (BAC) threshold for driving under the influence (DUI) in Maryland is 0.08. This means that if a driver's BAC measures at or above this level, they can be charged with a DUI. This threshold is based on a significant body of research demonstrating that impairment in motor skills, judgment, and reaction times begins to occur at this level of alcohol in the system.

In many jurisdictions, including Maryland, this standard is established to help reduce accidents and improve road safety. Driving at or above this BAC level implies that the driver may have impaired abilities to operate a vehicle safely, which is a primary concern for law enforcement and public safety advocates alike. This standard is consistent with national norms, where 0.08 is widely recognized as the legal limit for intoxication while driving.
