A New York state inspection sticker is used to notify law enforcement the vehicle has passed emissions testing. The sticker is necessary in New York in order for a vehicle's registration to be renewed.
In order for a driver to receive a New York inspection sticker the vehicle must comply with the state's emission laws. Failure to renew an inspection sticker can result in a fine or parking ticket. The owner of the vehicle will also be unable to renew the registration for that specific vehicle and will not be able to transfer the title to another individual.
New York state inspections are done at their specific Department of Motor Vehicle locations and by certified emission inspectors.
