What is the legal blood alcohol concentration (BAC) limit for individuals over 21 years of age?

The legal blood alcohol concentration (BAC) limit for individuals over 21 years of age in Washington is .08. This means that a driver with a BAC of .08 or higher is considered legally impaired, which can lead to severe penalties including fines, license suspension, and even imprisonment. The regulation is based on extensive research that indicates this level significantly affects judgment, coordination, and overall driving ability, increasing the risk of accidents.

Understanding this limit is crucial for safe driving behaviors and reinforces the importance of being aware of one's alcohol consumption before operating a vehicle. It's also important for individuals to know that there are additional restrictions for commercial drivers or those under 21 years of age, which have lower BAC limits.
