Section 20-509. Rates

a.  Except  as  otherwise provided, charges for the
  towing of vehicles shall not exceed fifty dollars for the first mile  or
  fraction  thereof  and four dollars for each additional mile or fraction
  thereof; provided, however, that where a motor vehicle has  been  booted
  by  a  person  licensed  pursuant  to subchapter 32 of this chapter in a
  private lot as defined in paragraph 3 of subdivision b of section 20-531
  of such subchapter and such vehicle is subsequently towed, no additional
  charge may be imposed for the towing of such vehicle.
    b. Except as otherwise provided, charges for storage of vehicles shall
  not exceed fifteen  dollars  for  each  twenty-four  hours  or  fraction
  thereof  for  the  first three days of storage and seventeen dollars for
  the fourth day of storage and each day thereafter.
    c. The commissioner may, by rule, authorize  such  additional  charges
  for  services  necessary  to prepare a vehicle for towing, including but
  not limited to charges for additional labor necessary for positioning  a
  vehicle  for  towing, which in the judgment of the commissioner shall be
  fair  and  reasonable.  In  promulgating  a  rule   pursuant   to   this
  subdivision, the commissioner shall consult with the tow advisory board.
    d.  (1)  No tow truck operator shall require the payment of any fee or
  charge for towing and storage  of  a  vehicle,  or  any  fee  or  charge
  directly  or indirectly related to towing and storage of a vehicle, that
  is not specifically authorized by law or rule.
    (2) No charge for the towing and storage of vehicles may be imposed by
  any person who does not have a license to engage in towing  as  required
  by  this subchapter at the time that the towing and storage services are
  performed.
