What is the blood alcohol content (BAC) limit for an adult to be considered legally drunk?

In Washington State, the legal definition of being considered legally drunk is established at a blood alcohol content (BAC) of 0.08. This means that an individual with a BAC at or above this level is presumed to be impaired while operating a motor vehicle.

This distinction is important because it not only guides law enforcement during traffic stops but also serves as a critical legal benchmark for driving under the influence (DUI) charges. The 0.08 BAC limit reflects research and consensus about the impairment caused by alcohol, indicating that individuals reaching this threshold are likely to experience reduced motor coordination, slower reaction times, and impaired judgment, which directly affect their ability to drive safely.

Higher BAC levels beyond this limit can further increase impairment, while lower limits may also lead to impairment but are not legally designated for the same consequences. Understanding this limit is essential for responsible driving behavior and complying with state laws to ensure safety on the roads.
