The rule
In Pennsylvania, the standard DUI statute applies to bicyclists. Pennsylvania's DUI statute (75 Pa.C.S. § 3802) applies to anyone driving, operating, or in actual physical control of a 'vehicle,' and the Vehicle Code's definition of vehicle does not exclude human-powered devices. Pennsylvania appellate courts have upheld bicycle DUI convictions. Penalties mirror auto DUI, including driver-licence suspension at higher BAC tiers and on repeat offenses. See 75 Pa. Cons. Stat. § 3802 (Driving under influence of alcohol or controlled substance).
Riding a bicycle while impaired is a real legal exposure in Pennsylvania. If you've been drinking, the safer move is to walk your bike, take transit, or call a ride.
