An adult is considered legally drunk if their blood alcohol content (BAC) is ______ or more.

An adult is considered legally drunk with a blood alcohol content (BAC) of 0.08 or more. This threshold is established by law in most states, including Washington, to determine when a driver is impaired due to alcohol consumption. At a BAC of 0.08, significant impairment of motor skills, judgment, and reaction time occurs, substantially increasing the risk of accidents and endangering both the driver and others on the road. Laws like this are in place to promote safety and reduce the incidence of alcohol-related crashes. Keeping the legal limit at 0.08 serves as a clear guideline for both law enforcement and drivers regarding responsible alcohol consumption and driving.
