(1) Any owner engaged in interstate operations of one or more fleets of apportionable vehicles may, in lieu of registration of the vehicles under chapter 46.16 RCW, register and license the vehicles of each fleet under this chapter by filing a proportional registration application for each fleet with the department. The application shall contain the following information and such other information pertinent to vehicle registration as the department may require:

     (a) A description and identification of each vehicle of the fleet.

     (b) The member jurisdictions in which registration is desired and such other information as member jurisdictions require.

     (c) An original or renewal application shall also be accompanied by a mileage schedule for each fleet.

     (d) The USDOT number issued to the registrant and the USDOT number of the motor carrier responsible for the safety of the vehicle, if different.

     (e) A completed Motor Carrier Identification Report (MCS-150) at the time of fleet renewal or at the time of vehicle registration, if required by the department.

     (f) The Taxpayer Identification Number of the registrant and the motor carrier responsible for the safety of the vehicle, if different.

     (2) Each application shall, at the time and in the manner required by the department, be supported by payment of a fee computed as follows:

     (a) Divide the in-jurisdiction miles by the total miles and carry the answer to the nearest thousandth of a percent (three places beyond the decimal, e.g. 10.543%). This factor is known as the prorate percentage.

     (b) Determine the total proratable fees and taxes required for each vehicle in the fleet for which registration is requested, based on the regular annual fees and taxes or applicable fees and taxes for the unexpired portion of the registration year under the laws of each jurisdiction for which fees or taxes are to be calculated.

     Applicable fees and taxes for vehicles of Washington-based fleets are those prescribed under RCW 46.16.070, 46.16.085, and 82.38.075, as applicable. If, during the registration period, the lessor of an apportioned vehicle changes and the vehicle remains in the fleet of the registrant, the department shall only charge those fees prescribed for the issuance of new apportioned license plates, validation tabs, and cab card.

     (c) Multiply the total, proratable fees or taxes for each motor vehicle by the prorate percentage applicable to the desired jurisdiction and round the results to the nearest cent.

     (d) Add the total fees and taxes determined in (c) of this subsection for each vehicle to the nonproratable fees required under the laws of the jurisdiction for which fees are being calculated. Nonproratable fees required for vehicles of Washington-based fleets are the administrative fee required by RCW 82.38.075, if applicable, and the vehicle transaction fee pursuant to the provisions of RCW 46.87.130.

     (e) The amount due and payable for the application is the sum of the fees and taxes calculated for each member jurisdiction in which registration of the fleet is desired.

     (3) All assessments for proportional registration fees are due and payable in United States funds on the date presented or mailed to the registrant at the address listed in the proportional registration records of the department. The registrant may petition for reassessment of the fees or taxes due under this section within thirty days of the date of original service as provided for in this chapter.
