No. Pennsylvania is considered a zero-tolerance state for motorists under the age of 21 who drive after consuming alcohol, as the legal drinking age in Pennsylvania is 21. Although the BAC limit for DUI is normally 0.08 percent, for drivers under the age of 21 the limit is 0.02 or more. As a result, virtually any amount of alcohol in an underage driver’s system will lead to a conviction for DUI. Any conviction for DUI for an underage driver can result in fines, jail time, and suspension of one’s driver’s license.
