Bicycle Highway-Access Laws in Pennsylvania
Last reviewed by BikeSize EditorialThis guide is for general information only and is not legal advice. Laws change - verify current rules with your state DOT or a licensed attorney before relying on this for any legal matter. Read full disclaimer.
The rule
Bicycles are prohibited on Interstate highways in Pennsylvania. 75 Pa.C.S. § 3511 prohibits pedalcycles and pedestrians on freeways and limited-access highways in Pennsylvania, including the entire Interstate system. PennDOT signs the prohibition at on-ramps; cyclists must use the parallel US and state-route network.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in Pennsylvania appears to use an Interstate, plan a detour before you start.
Bigger roads, longer rides
Size a road bike for shoulders, group rides, and rural highways
Highway-access and group-riding rules favour riders who can hold a straight line at speed. Start with a frame that fits.
