identification devices so that each powered vehicle owned or to be

operated by the motor carrier in the state shall bear one

identification device. Identification devices shall be issued on an

annual basis, and applications shall be made annually on the form

prescribed by the Commission, and any motor carrier operating a

powered vehicle without a current identification device shall be in

violation of the provisions of Sections 180 through 180m of this

title or the Motor Carrier Act of 1995.

It is hereby declared unlawful for any motor carrier, or agents

or employees of any motor carrier, to use or transfer an

identification device except as provided by rules of the Commission.
