N.Y. Comp. Codes R. & Regs. tit. 15, § 103.3
(e) As hereinafter provided, a registered dealer must provide the transferee with acceptable evidence of ownership and bill of sale which conforms to the requirements of subdivision (f) of this section.
(f) Bill of sale.
Every bill of sale issued by a registered dealer shall be consecutively numbered with a unique bill of sale identification number and shall contain the name and address of the dealer, the dealer's registration number, the name and address of the transferee, a complete description of the ATV including the year, make, model, identification number and number of wheels of the ATV, whether the ATV is new or used and the statement that the New York State and local sales taxes have been collected.
(g) Required records.
(h) If a dealer selling ATV's is registered pursuant to section 415 of the Vehicle and Traffic Law, the provisions of subdivisions (d), (e), (f) and (g) shall apply to such dealer except that with respect to subdivision (g), such dealer may include ATV's in his regular book of registry or he may maintain a separate book of registry for ATV's.
(i) Dealer demonstrator registration plates.
Upon issuance of an ATV dealer registration pursuant to section 2282 of the Vehicle and Traffic Law, two dealer demonstrator registrations and number plates with validating stickers shall be issued without fee upon the applicant's request made to the appropriate district office of the department. At that time, or thereafter, an applicant for ATV dealer registration may request the issuance of additional dealer demonstrator registration number plates with validating stickers from such district office upon payment of the appropriate fee of $8.25. The number of dealer demonstrator registration number plates to be assigned can be limited in the discretion of the commissioner. Such number plates together with the validating stickers may be temporarily affixed to an ATV being used for demonstration at the same location as regular number plates are attached. Dealer number plates issued to dealers under section 415 of the Vehicle and Traffic Law can be used by such dealers as ATV dealer demonstrator registration number plates. However, such a dealer may obtain ATV dealer plates upon submission of a proper application and fee.
