A bill to amend title 54, United States Code, to provide that State law shall apply to the use of motor vehicles on roads within a System unit.

Right now, the National Park Service sets its own rules for motor vehicles on roads inside national parks — which can differ from the state laws that apply just outside park boundaries. This bill would change that by making state motor vehicle laws, including rules about off-highway vehicles, apply on Park Service roads. If someone violates the applicable state law while driving in a national park, it would be treated as a federal prohibition. The practical effect is that states, not the Park Service, would determine what kinds of vehicles can use park roads.
