VTL section 403 (1):
§ 403. Number plates continued. 1. Notwithstanding any other
provision of this chapter, the commissioner, upon registration or
reregistration of any vehicle required to be registered under this
chapter, may continue the use of number plates for an additional period
as may be determined by him, in which event he shall issue and deliver a
tag or other evidence of registration, which shall be attached or
affixed in such manner as he may prescribe by regulation. The failure to
affix or display such tag or other evidence of registration, in the
manner prescribed by the commissioner, shall constitute a violation of
this section. The removal from any vehicle, other than by the owner of
the vehicle or person authorized by such owner or by a police officer in
the performance of his duties, of such tag or other evidence of
registration shall constitute a class B misdemeanor.
The commissioner specifies that the sticker must be affixed to the windshield.
