A Study of Alternative Strategies for Assessing Fees on Commercially Registered Vehicles

By: California Department of Motor Vehicles

This study was initiated by the Division of Registration and Investigative Services. The scope of the study was subsequently broadened to meet the requirements of Senate Concurrent Resolution (SCR) 11 of the 1983 legislative session. The final report for this study was submitted in July 1984. The objectives of this study were to: 1. develop a schedule for assessing weight fees on commercially registered power vehicles (6,500 or more pounds unladen) and trailers, based on declared laden or gross weight (GVW) of individual power vehicles and trailers (this schedule would replace the current unladen weight fee table; registration and vehicle license fees would continue to be collected); 2. develop a fee-assessment system for commercially registered power vehicles (6,500 or more pounds unladen) and trailers, based on the declared combined gross weight (CGW) of power vehicles (CGW would be declared for only power units and would include the total weight of the power unit, all trailing vehicles, if any, and all loads) and charging only a standard fee on each trailer (the CGW fee assessed on power vehicles and the trailer fee would replace the registration, vehicle license, and unladen weight fees currently collected on power vehicles and trailers); and 3. estimate the total 1985 revenue loss under a CGW fee schedule that would allow fees remaining on deleted interstate power vehicles to be credited toward fees due on their power vehicle replacements, and produce an adjusted CGW fee schedule that would recoup this revenue loss.
