Section 416. Limited use of dealer's and transporter's number plates by vendee or lessee

Upon  the  sale  or  lease  of  a  motor  vehicle  or
  motorcycle  the  vendee  or  lessee shall be allowed to operate the same
  upon the public highways for  the  period  of  five  days  after  taking
  possession  thereof,  without  carrying  number  plates  issued  upon  a
  registration under section four hundred one,  if  a  motor  vehicle,  or
  under  section  four  hundred  ten,  if a motorcycle, provided the motor
  vehicle or motorcycle shall have attached thereto and displayed thereon,
  in the manner therein provided,  a  set  of  dealer's  or  transporter's
  number  plates issued to the vendor or lessor under section four hundred
  fifteen, and if a proper application for registration and number  plates
  for  such  vehicle,  under the provisions of section four hundred one or
  four hundred ten, as  the  case  may  be,  shall  have  been  mailed  or
  presented to the commissioner, or agent, accompanied with the payment of
  the  required fee within twenty-four hours after he has taken possession
  thereof. If the motor vehicle or motorcycle is to  be  registered  in  a
  jurisdiction  other  than  the  state  of  New York, the requirement for
  filing or presenting such application shall not apply.
    No person shall operate or drive upon the public  highways  any  motor
  vehicle  or  motorcycle  on  which  is  fastened  or  displayed any such
  dealer's or transporter's number plates after a sale or  lease  of  such
  vehicle by the dealer or lessor, except in compliance with the foregoing
  provisions.
    A vendee or lessee to whom number plates are delivered or by whom they
  are held under the provisions of this section shall return the same, and
  the  accompanying  registration  certificate,  to  the  dealer or lessor
  before the expiration of six days after he took possession of the  motor
  vehicle or motorcycle purchased or leased. If number plates so delivered
  or  held,  or  such  certificate, are not returned within the time above
  limited, the dealer or lessor shall immediately notify the  commissioner
  of that fact by mail, describing the plates according to the general and
  distinctive numbers and characters thereon.
    The  provisions  of this section shall apply also to the sale or lease
  of a trailer and to the use by the  vendee  or  lessee  of  dealer's  or
  transporter's  number  plates on the trailer sold or leased, and for the
  purpose of applying such provisions a trailer shall be deemed  to  be  a
  motor vehicle.
