Research Studies & Reports
DMV’s Research & Development Branch has been conducting research and producing studies and reports since the 1950s. Research & Development reports help DMV to measure the impact of new laws on making drivers safer. We also identify areas where we can improve our processes, explore new approaches to solving existing problems, and branch out into new opportunities to serve you better.

A Cost Study of “Substitute License Plates” Vs “Duplicate License Plates”To determine the relative advantages of the Department of Motor Vehicles' present system of issuing substitute plates when a license plate is lost, stolen, or mutilated with a proposed system of issuing duplicate plates. In addition, a procedure for issuing duplicate plates is suggested and a cost comparison is made between the proposed system and the present system. |

Projected Motor Vehicle Registration & Drivers Licenses Outstanding 1970-1990The ownership of motor vehicles in California has long been used by economists, bankers, planners, and administrators at all levels of government and the private sector as an important measure of the State's economy. Members of these professions have continued to seek long-range estimates of vehicle registration data in order to forecast future growth and development of the State and to plan necessary facilities for this expected growth. This is the third set of estimates released by the department. In addition, for the second time, are included estimates on number of drivers license holders by county (to 1976) and statewide (to 1990). It is anticipated that these registration estimates will need revision at least every two years and perhaps more frequently should drastic changes occur in the base estimators. A multiple linear regression model was employed as the statistical tool to the development of the estimates. Separate equations were developed for each vehicle type (passenger vehicles, commercial vehicles, trailers and motorcycles) for each of the 58 counties of California. The predictor variables used were total population and year. The county population estimates were provided by the department of Finance and reflect the statewide totals. |
