In Pennsylvania, it is a serious offense to drive under the influence of alcohol or a controlled substance. This offense is known as DUI, driving under the influence. If you are a minor (under the age of 21) and you are caught driving under the influence, your penalties will be severe. According to Title 75 section 3802(e) of the PA crimes code, a minor may not drive, operate or be in actual physical control of the movement of a vehicle after imbibing a sufficient amount of alcohol such that the alcohol DUI first offense concentration in the minor's blood or breath is 0.02% or higher within two hours after the minor has driven, operated or been in actual physical control of the movement of the vehicle. Factors such as your Blood Alcohol Concentration (BAC) and whether it is your first offense or not do not matter when it comes the severity of your DUI if you are a minor.
