2006 New York Code - Repairs.

 
    §  20-514  Repairs. a. No licensee under this subchapter or his or her
  agent shall make repairs or cause repairs to be made for a  fee  on  any
  vehicle  which  requires  towing  because of a vehicular accident and is
  towed by such licensee, without first entering into a  signed  agreement
  with  the  person in charge of the vehicle authorizing such repairs. The
  commissioner shall prescribe the form to be used for such agreement.  In
  addition  to  any  other  information  required  to be set forth in such
  agreement, the commissioner shall require that such agreement set  forth
  the  registration number assigned to the licensee's repair shop pursuant
  to section three hundred ninety-eight-c of the vehicle and traffic law.
    b. In any case where the tow truck operator knows that the  person  in
  charge  of  a  vehicle is injured and is to be removed to a hospital, it
  shall be unlawful to enter into an agreement  authorizing  repairs  with
  such  injured  person  until  the  expiration  of  a  period of at least
  twenty-four hours from the time of  the  accident,  unless  the  injured
  person  is  not  admitted  to  or  has been discharged from the hospital
  before the expiration of such period.
