For more details or access, contact the National Park Service.

Truck mapDesignated (STAA) Truck Routes

Certain “STAA” vehicles (Twin trailers, triple saddle mounts and automobile and watercraft transporters) are required to use the designated Surface Transportation Assistance Act (STAA) highway system for travel in Virginia. These highways are not posted with signs indicating they are part of the designated system.

This system includes the National Network (all interstates and certain primary routes), the Virginia Qualifying System (including various other state primary highways) and the Virginia Access System, which provides direct access to certain terminals.

Note: Triple saddle mount combinations more than 75 feet long (up to the maximum allowable length of 97 feet) may only travel on the National Network.

Trucks may travel up to one road-mile of travel off the National Network and Virginia Qualifying Highways (but not the Virginia Access System) to reach terminals, fuel, food, rest and repairs.

These designated highways are on the Virginia Truck Routing Map available here.

A printed version of the map is also available at major safety rest areas and welcome centers.

Special Use Permit

A special use permit can be obtained free of charge where travel by “STAA” vehicles beyond the allowable one road-mile off the designated STAA system is required to reach a terminal for delivery or pick-up.

Contact DMV's Hauling Permit Section at 804-497-7135.

For permission to access terminals off the designated system within cities and towns or in Henrico and Arlington counties, contact locality officials.
