Providers must display identification markings on the driver and passenger side of the vehicles.

The markings must include the name of the provider as registered with the commission and the certificate number. Provided however, providers holding both intrastate and interstate authority may display either the U.S. Department of Transportation certificate number, commission certificate number, or both.

The markings must be clearly legible, with letters no less than three inches high, in a color that contrasts with the surrounding body panel. Leased vehicles may display either permanent markings or placards on the driver and passenger sides of the vehicle.

Vehicles operated by or under lease must display the name and permit number of either the business operating the vehicle or the registered owner. The markings may be permanent or placards on the driver and passenger sides of the vehicle.

When identification of the provider would create an embarrassment to the persons with special transportation needs, the name of the provider may be omitted when authorized by letter from the secretary of the commission.
