24 Va. Admin. Code § 30-580-10
It is the philosophy of the Commonwealth Transportation Board that all vehicles should have access to the roads on which they are legally entitled to travel. Travel by any class of vehicle on any class of highway should be restricted only upon demonstration that the restriction will promote the health, safety and welfare of the citizens of the Commonwealth without creating an undue hardship on any of the users of the transportation system. The board recognizes that there may be a limited number of instances when restricting through trucks from using a segment of a primary or secondary roadway will reduce potential conflicts, creating a safer environment and one that is in accord with the current use of the roadway. The board has adopted these guidelines to govern and regulate requests for through truck restrictions on primary and secondary highways.
