Drivers who transport manufactured housing on highways must have the proper commercial driver license (CDL) if the vehicle meets the weight criteria for a commercial motor vehicle (CMV) as defined in 49 CFR § 390.5. In determining whether the towed unit exceeds 10,000 pounds and whether the gross combination weight rating (GCWR) totals 26,001 or more pounds, the manufactured housing being drawn and trailers carrying the manufactured housing are motor vehicles for purposes of the Act.
