Tax Law, § 502(1)(b)
Examples.
Example 1:
Carrier A operates tractor-trailer combinations used to transport new cars. Special permits and stickers do not apply to this operation since the trailer, on which the new cars are carried, is not part of a saddle or full mount mechanism, or combination of both.
Example 2:
Carrier B delivers new trucks "piggy back." The unloaded weight of each trunk involved is 10,000 pounds. This is a saddle mount operation to which special permits and stickers would apply. The declared maximum gross weights for this carrier's special permits and stickers should be 20,000 pounds and the unloaded weight should be 10,000 pounds. Highway use tax should be reported on the tax return at $.006 per mile if reported on maximum gross weight basis or $.005 if reported on unloaded weight basis. (See section 481.1 of this Title.)
Example 3:
Carrier C has an operation whereby three vehicles are delivered under simultaneous movements. The motive powered vehicle in this operation has fully mounted on it a second vehicle. The third vehicle's front wheels rest on the rear chassis of the first vehicle and its rear wheels are on the highway. This is a combination saddle and full mount mechanism, to which a special permit and sticker applies.
Example 4:
Carrier D transports two vehicles "piggy back." The motive-powered vehicle and the vehicle carried thereon each weigh 8,500 pounds. A special highway use permit and sticker must be used for the motive-powered vehicle if the carrier elects to compute the tax on the unloaded weight method. (See section 481.9 of this Title.) Its unloaded weight is 8,500 pounds and its maximum gross weight is 17,000 pounds. If carrier D reports on the maximum gross weight basis, no permit is required for this vehicle and the mileage for this movement is not taxable since the maximum gross weight of the vehicle involved is not over 18,000 pounds. Under the unloaded weight method, the mileage over New York State public highways is taxable at the rate of $.004 per mile.
