§ 398-k. Improper display of signs. 1. The holder of a repair shop
registration shall remove or cause to be removed any sign which contains
the registration number of the station which is visible to the public
and which is required to be displayed by this article or regulations
promulgated thereunder if the registration is revoked or suspended or
the repair shop is out of business. If the registration is only
suspended, the holder may cover up the sign instead of removing it.

2. No person shall permit the display of any sign required to be
displayed by this article or regulations promulgated thereunder
indicating to the public that an official repair shop is operating
unless a repair shop registration has been issued to that person and is
currently valid.
