The marking requirements for Commercial Motor Vehicles (CMVs) are found in §390.21. The markings need to be displayed on both sides of the vehicle, including:
The FMCSA does not regulate how a vehicle is branded, what they do care about is quickly identifying which company or carrier is currently operating the vehicle. If there are multiple names on the vehicle, this could be a confusing task leading to uncertainty. For this reason, if there is more than one name on the vehicle, the vehicle marking needs to include the words “operated by” followed the legal or single trade name of the company operating the vehicle, then the letters “USDOT” followed by the carrier’s identification number issued by the FMCSA. Only one USDOT number may be visible on the vehicle.
Vehicles that are rented or leased for more than 30 days need to be marked as above. Since rentals often carry the renting company’s name, the vehicle would need to be marked using the “operated by” provision above.
When the rental is less than 30 days, the vehicle may be marked with the rental company’s name and USDOT number if the rental/lease agreement entered into conspicuously contains the following information:
When a driver owns his or her own vehicle and is “leased on” with a carrier, for compliance purposes, the driver is considered an employee of the carrier. The leased driver’s vehicle needs to be marked with the carrier’s name and USDOT number, even if the driver has their own USDOT number or authority.
