Bicycle Highway-Access Laws in Pennsylvania

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. Read the national cycling on highways guide for comparison. For low-light road and group visibility, compare bike lights for commuting and unlit roads.
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.
