Notes

Pennsylvania is one of a small number of states with an explicit statewide rule. 75 Pa.C.S. § 3508(b) prohibits riding a pedalcycle on a sidewalk in a business district unless permitted by an official traffic-control device. Outside business districts, sidewalk riding is allowed but § 3508(a) requires the rider to yield to pedestrians and to give an audible signal before overtaking. Philadelphia adds its own ordinance restricting sidewalk riding by anyone aged 13 or older citywide.

Penalty

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.

Conditions
