What is the legal maximum blood alcohol concentration (BAC) for drivers over 21 in Washington State?

In Washington State, the legal maximum blood alcohol concentration (BAC) for drivers over the age of 21 is 0.08%. This means that if a driver is found to have a BAC at or above this level, they are considered to be driving under the influence of alcohol, which can lead to legal penalties, including fines, license suspension, and potential jail time.

The BAC limit is established to ensure that drivers are in a condition to operate a vehicle safely. Studies have shown that alcohol impairs judgement and reaction times, increasing the likelihood of accidents. Therefore, maintaining the BAC limit at 0.08% is crucial for road safety and helps to reduce the incidence of alcohol-related crashes.

Other options reflect lower or higher thresholds that do not align with the law in Washington. For drivers under 21, there is actually zero tolerance for alcohol, meaning any measurable amount can lead to charges. Meanwhile, limits like 0.10% and 0.12% are outdated or pertain to different jurisdictions, and would not be applicable under current Washington State regulations.
