Representatives of the Chief of Police and the Director are hereby authorized to make inspections under the provisions of this Subtitle. They shall have the right at any time, after identifying themselves to the driver or owner, to enter into, or upon any taxicab for the purpose of ascertaining whether or not any provision of this Subtitle has been violated. Refusal of the driver or owner of any such vehicle to stop the vehicle when ordered to do so by such representative, or to permit any such representative to enter into the vehicle for such purposes, or refusal to display the certificate, license, or any other document required under this Subtitle to be carried in the vehicle, upon his demand, shall constitute a violation of this Subtitle and shall be sufficient grounds for revocation, or suspension of the license or certificate. If, upon inspection, it is determined that the copy of the duly authorized certificate carried in the vehicle does not correspond to the vehicle, the certificate holder may be deemed to have violated Section 20-148(a) of this Subtitle and shall have his/her certificate revoked by the Director. Where a company fails to maintain the appropriate certificate in a vehicle operating as a taxicab and a driver is issued a citation by law enforcement officials as a result of such failure, the driver shall provide a copy of the citation to the Director within fifteen (15) business days of receiving the violation. The Director shall keep a permanent record of all such citations received pursuant to this subsection.
