Weight, height and width restrictions 

Certain bridges and tunnels have additional weight, height, and width limitations posted.  

A list of restricted structures (due to height, width and weight) on state-maintained roadways  is available upon request:

Trucks and other vehicles over 13 feet 6 inches high are prohibited on Interstate 64 west at the Hampton Roads Bridge-Tunnel, on Interstate 264 through the Downtown Tunnel (either direction) and on Route 58 through the Midtown Tunnel (either direction.)

Tractor trailers wider than 8 feet are prohibited on I-264 west through the Downtown Tunnel. Additional details and alternative routes

Designated truck routes

Twin trailers, triple saddle mounts and automobile and watercraft transporters must use the designated Surface Transportation Assistance Act (STAA) highway system in Virginia,

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.

These routes are shown on the Virginia Truck Routing Map, along with related vehicle and length-based restrictions.

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

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.

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 free where travel beyond the allowable one 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, by fax at 804-367-0063.

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

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

Length restrictions

Various highways have restrictions on the length of “through” trucks or other vehicles or configurations.

These highways are posted and specify a particular vehicle (e.g. “No Thru” trucks, tractor-trailers etc.) or a certain length (e.g. “No Thru Trucks over 35 feet”).  

There are a number of routes posted with a warning indicating “Trucks Not Recommended.” These roads have undesirable conditions. Drivers are strongly encouraged to avoid them.

There are a small number of (non-interstate) routes where tractor-trailers over 65 feet are prohibited.

These restrictions are shown on the Virginia Truck Routing Map, which also indicates the designated STAA system.

Temporary restrictions and incidents 

Various ad-hoc restrictions can exist at any time due to weather, incidents or construction, etc.sdfv

For information on current traffic conditions, incidents, temporary restrictions, road closures, etc., go to or call 511 toll free.

Other restrictions

Several highways in Virginia are federally maintained and have restrictions on commercial access. These include the Blue Ridge Parkway, George Washington Memorial Parkway, Colonial Parkway and Skyline Drive. 

Contact the National Park Service for details.
