Question: 1 / 400

What is the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 in Pennsylvania?

0.05%

0.08%

In Pennsylvania, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is 0.08%. This means that a driver may not have a BAC that exceeds this level while operating a vehicle. Several studies and legal standards have shown that a BAC of 0.08% is a threshold at which impairment typically begins to affect an individual's ability to operate a vehicle safely.

At this level, drivers are more likely to experience reduced coordination, slower reaction times, and impaired judgment, all of which can significantly increase the risk of accidents. Law enforcement and the legal system enforce this limit to promote road safety and reduce the incidence of alcohol-related traffic violations.

In Pennsylvania, having a BAC above this legal limit can lead to serious legal consequences, including fines, license suspension, and even potential imprisonment. Understanding and adhering to this limit is vital for ensuring the safety of all road users.
