All motor carriers must equip their motor vehicles with an odometer or other satisfactory device to record accurately the cumulative mileage traveled by the vehicle. Such device must be kept constantly in good operating order, may not be a device designed to be reset to zero, and may not be adjustable by the operator of the vehicle. Additional devices for recording trip mileage are allowed, but not in lieu of the requirements stated above.
