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

In Pennsylvania, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is set at 0.08%. This means that if a driver's BAC is at or above this level, they can be charged with driving under the influence (DUI). The 0.08% limit is a standardized measure that indicates a level of intoxication that can impair a driver's ability to operate a vehicle safely.

Understanding the legal limit is crucial for drivers to be aware of the potential consequences of alcohol consumption before getting behind the wheel. Many other jurisdictions also use the 0.08% limit, making it a widely accepted benchmark for legal impairment. Different limits apply to specific groups, such as commercial drivers or drivers under the age of 21, highlighting the importance of tailored regulations to ensure safety on the roads.
