No. Interstate for-hire carriers may not display their ICC-MC number instead of their DOT number. These carriers are required to have operating authority and an MC-number, but they must display the USDOT number on all vehicles. Carriers are not required to remove existing MC number marking, but are encouraged not to display the MC number on new or repainted CMVs.
