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.

The Psychometric Prediction of Negligent Driver Recidivism
To determine whether the subsequent driving record of problem drivers could be predicted following a group driver improvement meeting, and to assess the contribution of psychometric and personality test variables in improving prediction.
The Prediction of Driving Record Following Driver Improvement Contacts
To construct prediction equations for post-contact driving records based on three data sources-prior driving record, driver questionnaire responses, and driver improvement analyst (DIA) interview information.
An Evaluation of California’s Drivers Licensing Examination
To assess the ability of the written knowledge test and the drive test to screen out accident-prone drivers; to provide descriptive data on the licensing process, with particular interest in the performance of older drivers.
An Evaluation of the California Driver Knowledge Test and the University of Michigan Item Pool
To evaluate both the written DMV driver licensing test and a large sample of driver knowledge test items selected from the University of Michigan's Highway Safety Research Institute (HSRI) item pool.
Language Survey – Summary Report of a Statewide Field Office Survey Taken to Determine Language Characteristics of Non-English Speaking
To conduct a survey to determine the number of non-English-speaking persons attempting to utilize services provided at DMV facilities.
How the Public Views DMV
To conduct a survey to determine the general public’s view of DMV.
Longitudinal Study of California Driver Accident Frequencies I: An Exploratory Multivariate Analysis
To attempt to develop an optimum accident-prediction system.
Driving Record and Recidivism Following the Purging of Driver Control Action Files
To evaluate adequacy of the department's driver action purge policies by analyzing the subsequent driving record of subjects whose files had been previously purged.
The Effectiveness of Traffic Safety Material in Influencing the Driving Performance of the General Driving Population
To develop new traffic safety materials, tailoring some to the age and sex of the recipient; to determine if mailing such materials to California drivers would reduce subsequent accidents and convictions
The Effects of Range vs. Non-Range Driver Training on the Accident and Conviction Frequencies of Young Drivers
The purpose of this study was to compare the relative effectiveness of a driving range vs. non-range driver education program in increasing skill and reducing accidents and convictions among teenage drivers.
