Most drivers are, or should be, aware of the so-called legal limit. Under Pennsylvania law, and the law of every other state, it is illegal for drivers over age 21 to drive with a blood alcohol concentration (BAC) of 0.08% or higher. Police who detain a driver can administer a BAC test. Drivers consent to these tests in advance, when they receive a driver's license. Any driver found to have a BAC of 0.08% BAC is said to have committed DUI per se. However, there is a lot more to the way Pennsylvania DUI law treats BAC.
You try to be cautious and courteous while you are driving, and you avoid getting behind the wheel after having anything to drink. However, you recently received a prescription for medication that makes you feel dizzy and sleepy. Is it possible that you and other Pennsylvania residents could face a DUI for driving after taking medication?
