In Maryland, at what Blood Alcohol Concentration (BAC) is a driver considered to be driving under the influence of alcohol per se?
The answer
Answer: A. According to the Maryland Driver's Manual, Maryland law considers drivers to be driving under the influence of alcohol when their blood alcohol concentration (BAC) reaches 0.08 percent or higher. However, physical coordination and driving judgment may be seriously impaired at much lower BAC levels. Vision, coordination, and reaction time can be significantly impaired after just one drink, increasing crash risk well below the legal threshold.
