When a vehicle is
  situated so as to constitute an obstruction to traffic, and such vehicle
  is unattended or the person in charge of such vehicle has  not  arranged
  for  its  removal,  a  police  officer  or  a  person  designated by the
  commissioner of transportation  may  direct  its  removal  by  a  person
  licensed  to  engage  in  towing,  and  such  licensee shall remove such
  vehicle to a storage facility which meets the specifications established
  by the commissioner by regulation pursuant to  section  20-508  of  this
  subchapter.  Such  licensee  shall  be  entitled to charge the person in

  the rendering of services to prepare the vehicle for towing at the rates
  set forth or authorized by section 20-509 of this subchapter.
