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.

| NRN062 | 1994/ 12 |
Evaluating DUI Program Impact in Quasi ExperimentsTo increase awareness of the need for rigorous research designs in evaluating DUI intervention programs and to present examples where quasi experiments have produced relatively equivocal results. |

NEGLIGENT-OPERATOR TREATMENT EVALUATION SYSTEMThis report is the last in a series which originally began with the creation of the Post Licensing Control Reporting and Evaluation System (PLCRES) in 1976 and extended in 1983 by a modified version of that system (Negligent Operator Treatment Evaluation System). The present report is being issued as an internal technical report of the Department of Motor Vehicles' Research and Development Section rather than an official report of the State of California. The findings and opinions may therefore not represent the views and policies of the State of California. |

The 1964 California Driver Record Study (Part 1: An Introduction and Methodological Description)The basic purpose of the overall study was threefold: (1) to provide data for operational and budgetary planning, (2) to provide basic descriptive and baseline data on drivers and driving record variables, and (3) to further understanding and knowledge about the nature and causes of traffic accidents. |

Development of a Driver License Application Management Information System Stage IIThis project involved creating a prototype off-line driver license (DL) application management information system (MIS) that captured and stored extensive information on the driver license application process. From this prototype database, example reports were generated to demonstrate the feasibility of constructing a fully functional off-line DL application MIS that would be able to provide descriptive measures and statistical data related to the driver licensing process. In the event that Department of Motor Vehicles’ management decides to proceed with the creation of the proposed database, funding from the California Office of Traffic Safety would be requested for the next stage, Stage III, of the project. The implementation schedule for Stage III is provided in this report. Specifically, Stage III will involve addressing and correcting problems with the application transaction source data that were identified in this report and constructing a fully functional DL application MIS. |

| 33.1 | 1970/ 07 |
An Abstract of Prediction of Driving Behavior Following a Group Driver Improvement SessionTo determine the extent to which driving record subsequent to a driver improvement meeting could be predicted from a personality test and biographical questionnaire. |
IV | |
| 84 | 1982/ 06 |
A Statistical Model of Individual Accident Risk Prediction Using Driver Record, Territory and Other Biographical FactorsTo determine (1) the relative importance of territory, prior driving record, and other variables in predicting future accident involvement; and (2) whether a driver's area of residence is a fair and actuarially sound rating factor. |

| NRN039 | 1967/ 07 |
The Measurement of Warning Letters on Two Dimensions: Threat and IntimacyTo develop letters that vary in the degree of threat and intimacy of style for use with negligent drivers. |
IV | |
| NRN042 | 1968/ 07 |
The Prediction of Driver Behavior Subsequent to Receipt of Official Letters of ReprimandTo isolate factors that predict the quality of a driver's record following receipt of various styles of warning letters. |
IV | |
| NRN044 | 1970/ 01 |
The Relationship of Perceptual Style of Drivers to Accident/Violation ExperienceTo explore the ability of the Stimulus Accretion Impending Hazard (SAIH) test to measure drivers' propensity for accident or violation involvement. |
IV | |
| NRN048 | 1975/ 12 |
The Effects of Anonymity on Subject Ratings of Driver Improvement Meetings: Questionnaire Response Bias as a Function of Respondent AnonymityTo determine if self-report information by drivers is more candid if collected under anonymous conditions. |
