Pennsylvania has beautiful and challenging opportunities for all-terrain vehicle (ATV) riding. Many trails have been developed on public and private lands to accommodate this recreational pursuit. This resource summarizes the ATV requirements of state law and regulations. The state law is known as the Snowmobile and All-Terrain Vehicle Law and is contained in Chapter 77 of the PA Vehicle Code. The state regulations are in Title 17 Pa. Code Chapter 51. This pamphlet is not intended to be a substitute for the actual law and regulations. In addition to state law and regulations, riding on municipal and private property may be further regulated by municipal ordinance.
