Vehicle Marking FAQs

The proper marking of commercial motor vehicles (CMVs) raises many questions for enforcement and compliance teams. To help clarify the requirements, the following answers address some of the most common questions received by J.J. Keller DOT experts about federal or interstate marking regulations.

  • All self-propelled or motorized CMVs must be marked. This includes any vehicle that furthers interstate commerce on a highway with a weight or combined weight (rated or actual) of over 10,000 pounds, passenger vehicles with a seating capacity of more than 8 or more than 15 passengers (depending on compensation), and any vehicle or combination of vehicles carrying a placardable amount of hazardous materials.

  • There is no federal minimum letter size requirement. The markings must be visible from 50 feet during daylight hours while the vehicle is stationary. Letters of at least 1.5 inches are recommended. States may have specific size requirements.

  • The letters must contrast sharply with the background they are placed on. For instance, black letters are fine on a light-colored vehicle, but would not stand out sufficiently on a dark vehicle.

Any time a vehicle meets the federal definition of a CMV, the vehicle must be properly marked so the public and enforcement know who is responsible for the vehicle’s safe operation. While the federal marking requirements are consistent, states may have rules that are different, but most allow interstate vehicles that are properly marked to operate without additional requirements.
