Example (1). A applies to register a 3-axle single unit truck in State R, a member of the International Registration Plan, on November 1, 1985. State R registers vehicles based on unladen weight. At the same time, A applies for a proportional registration under the IRP to use the truck in State S. State S does not register vehicles on the basis of unladen weight. For purposes of the proportional registration in State S, A declares the gross weight of his truck at 50,000 pounds. A does not register the truck in any other states. A's truck has a taxable gross weight, as determined under § 41.4482(b)-1 , of less than 55,000 pounds and therefore is not subject to tax under section 4481(a). A submits a written statement along with his application for registration in State R. The written statement states that A's vehicle has a taxable gross weight of less than 55,000 pounds and is signed by A. State R may register A's truck and issue a proportional registration for A to use his truck in State S without receiving proof of payment.
Example (2). Assume the same facts as in example (1) except that A applies for proportional registration under the IRP in State S and declares the truck to have a gross weight of 60,000 pounds. The taxable gross weight of A's truck, as determined under § 41.4482(b)-1 is 60,000 pounds. State R may not register A's truck unless it receives proof of payment within the meaning of paragraph (c) of this section.
Example (3). On October 10, 1985, C applies to register 9 vehicles in State U and declares the gross weight of each vehicle to be 70,000 pounds. C has not applied for registration in any other states. At the time of applying for registration, C presents a photocopy of a receipted Schedule 1 (Form 2290) that shows a total of 9 vehicles which are subject to tax under section 4481(a) and for which tax is not suspended under § 41.4483-3(a) . The vehicle identification numbers of the vehicles that C is seeking to register must be listed on the Schedule 1 in order for State U to register the vehicles.
