N.Y. Comp. Codes R. & Regs. tit. 15, § 79.4 – Inspection information.

(a) Upon application to the commissioner, the owner of a motor vehicle required to be inspected may request an extension of time to have the inspection made. Such extension of time, not to exceed 10 days, may be granted by the commissioner if, in his discretion, reasonable grounds exist for its issuance. The extension must be affixed to the motor vehicle in the lower left corner of the inside of the windshield or kept with the vehicle registration if the vehicle has no windshield, or is a trailer or motorcycle.
(b) Where a nonresident becomes a resident of this State, a certificate of inspection issued by any other jurisdiction to a motor vehicle owned by him will be accepted in lieu of a certificate of inspection issued in this State. Such a certificate will be valid until the expiration date of the out-of-state certificate, or one year from the date of New York registration, whichever occurs first. Upon expiration of the out-of-state certificate, the motor vehicle must be inspected and bear a certificate of inspection from an official New York inspection station.
(c) A certificate of inspection issued by any other jurisdiction which has a compulsory periodic inspection program to a motor vehicle which is concurrently registered (vehicle registered in more than one jurisdiction) in this State and in the state or province of Canada which issued the certificate of inspection will be accepted in lieu of a certificate of inspection issued in this State. Such a certificate will be valid until the expiration date of the out-of-state certificate, provided the motor vehicle remains registered in such other state or province of Canada. For purposes of this Part, a vehicle with an International Registration Plan registration will be deemed registered in every jurisdiction in which it may legally be operated.
(d) The owner of a motor vehicle that is registered in the NYMA and that is subject to a diesel emissions inspection, whose motor vehicle inspection certificate will expire while outside the NYMA or who purchases a vehicle from outside the NYMA may apply to the commissioner for a temporary certificate of emissions waiver (form VS-1078) prior to receiving an inspection. The temporary certificate of emissions waiver will be valid with a valid New York State safety inspection certificate (form VS-1082) or heavy vehicle safety inspection certificate (form VS-1082HV) for as long as the registered vehicle is outside the NYMA. A diesel-powered motor vehicle that is registered in the NYMA and that is exempt from emissions inspection does not require a temporary waiver, may be inspected at any inspection station licensed to inspect such vehicles, and does not need to be reinspected upon return to the NYMA.
1. (1) [Reserved]
2. (2) A vehicle subject to the diesel emissions inspection that is presented for inspection with a VS-1078 outside the NYMA must receive the appropriate safety inspection and, when it passes said inspection, shall receive the appropriate safety inspection certificate.
3. (3) The temporary certificate of emissions waiver will be valid for 10 days after entry into the NYMA by the motor vehicle. Upon re-entry to the NYMA, and prior to the expiration of the 10 days, the subject vehicle must receive the complete appropriate diesel emissions/safety inspection.
4. (4) Vehicles that are subject to an OBD II inspection and registered in the NYMA, that are inspected outside the NYMA, shall receive a complete safety and OBD II inspection and when such a vehicle passes said inspection, shall receive a safety/emissions inspection certificate (form VS-1082SE). This certificate shall be valid in the NYMA; the vehicle does not require reinspection, and a VS-1078 is not required.
