The purpose of Tra 304 is to establish procedures and criteria for permits for the movement of non-divisible vehicles, objects, or vehicles and loads having weight, width, height, or length greater than statutorily allowed limits set forth in RSA 266. Pursuant to RSA 266:24, the commissioner, with the approval of the director of motor vehicles, department of safety, has authority to grant permits that specify routes and times of travel for movement of oversize, overweight, or both, vehicles, objects, or vehicles and loads. These permits authorize travel only on those state maintained roads and bridges over which the department of transportation has jurisdiction, that is, the state highway system.
