Designated Truck Routes

For travel on highways in Virginia; Twin-trailers, Triple Saddle mounts, and Automobile or Watercraft Transporters must use the designated (STAA) highway system. This system is comprised of the National Network which includes all interstates and certain primary routes; the Virginia Qualifying system which includes various other state primary highways; and the Virginia Access system which provides direct access to certain terminals.

These designated routes are shown on the Virginia Truck Routing Map as well as other related vehicle and length-based restrictions (as discussed below) and can be accessed here. A printed version of the map is also available at major safety rest areas and welcome centers. For a printable listing of the non-interstate portion of the designated system click here. For a map of safety rest areas and welcome centers in Virginia click here.

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

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

Special Use Permit

A Special Use Permit can be obtained at no charge where travel beyond the allowable one mile of access 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 or by sending a fax to 804-367-0063. For permission to access terminals off the designated system within cities and towns and in Henrico and Arlington counties, contact officials in those localities.  

For additional questions regarding designated (STAA) truck routes, and length restrictions or limitations on state-maintained roads contact The Virginia Department of Transportation at 1-800-FOR-ROAD (1-800-367-7623).

Length Restrictions

Various highways have restrictions on the length of “through” trucks or other vehicles or configurations. These highways are posted by signs on the roadway and specify a particular vehicle (e.g. “No Thru” trucks, tractor-trailers etc.) or a certain length of vehicle (e.g. “No Thru Trucks over 35 feet”).   These also include a number of routes posted with an advisory warning indicating “Trucks Not Recommended.” These roads present undesirable conditions which drivers are strongly encouraged to avoid .

In addition, there are a small number of (non-interstate) routes posted with signs prohibiting tractor-trailers over 65 feet altogether.

These various restrictions for state-maintained highways are shown on the Virginia Truck Routing Map (which also indicates the designated STAA system as discussed above) which is available online here or here (for a printable listing).

Temporary Restrictions and Incidents 

Various ad-hoc restrictions due to weather, incidents or construction etc. may exist at any given time throughout the state. For information on current traffic conditions, incidents and temporary restrictions, road closures, etc. go to or call * 511 toll free.
