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.

Knowledge and Attitude Change and the Relationship to Driving Performance Among Drivers Attending California Traffic Violator School.One of the primary goals of the traffic violator school (TVS) program is to improve knowledge and attitudes toward traffic safety issues among drivers cited for traffic violations. While the TVS curriculum is standard for all courses, the courses may differ in content emphasis and other factors. Among the specific characteristics on which TVS programs differ are comedy versus non-comedy presentation modes, public versus private ownership, and use of advertising inducements. The present study examined how these d ifferences may influence t he amount of learning and attitude change resulting from TVS attendance. The results indicate that the amount of improvement in knowledge and positive attitude was not significantly related to method of instruction, type of provider, or use of an inducement to attract enrollees. No significant relationship was found between knowledge gain and s ubsequent accident involvement, or between attitude change and subsequent driver record entries. It was also found that although level of knowledge gain was associated with fewer subsequent traffic citations, the magnitude of the relationship was small. It was recommended that, to the extent that one of the goals of TVS is to increase knowledge of safe driving practices, there may be some value in requiring an exit test as a condition for receiving a TVS-completion certificate. However, there is no evidence at this time to conclude that such an increase in knowledge would result in a reduction in subsequent accident involvements. |

AN EVALUATION OF THE EFFECTIVENESS OF CALIFORNIA DRINKING DRIVER PROGRAMSThere has been longstanding interest in determining which sanctions work best to reduce drunk driving. This study, mandated by the California Legislature (SB 1344) and funded by the California Department of Alcohol and Drug Programs (DADP), examined the degree to which first offender, SB 38 and 30-month drinking driver programs (DDPs) in California reduced drunk driving recidivism, relative to other sanctions, such as driver license suspension. Based on the findings from this study, as well as those from prior research, this report recommends combining alcohol treatment with driver license actions as the best strategy for reducing drunk driving recidivism and enhancing overall traffic safety. |

1995 ANNUAL REPORT OF THE CALIFORNIA DUI MANAGEMENT INFORMATION SYSTEMIn this fourth annual report, 1992 and 1993 DUI data from several diverse sources were compiled and cross-referenced for the purpose of developing a single comprehensive DUI data and monitoring system. This report presents crosstabulated information on DUI arrests, convictions, court sanctions, administrative actions and alcohol-involved accidents. In addition, this report provides an evaluation of the effectiveness of alternative court and administrative sanctions (including alcohol treatment programs and license actions) upon the postconviction records of first and second DUI offenders. The postconviction driving records of DUI offenders arrested in 1989, 1991, and 1992 were evaluated for four-, two-, and one-year periods, respectively. |

An Inventory of California Driver Accident Risk FactorsThis report is a statistical compilation of accident-risk factors identified through a preliminary analysis of driver record information extracted in May 1992, providing driving record information through December 1991. The information is presented in relatively raw tabular form with minimal narrative and interpretation. The goal is to provide report recipients and users with a comprehensive array of up-to-date accidentrisk information. More formal and comprehensive analyses will be published at a later date. |

THE RELATIONSHIP BETWEEN DRUG ARRESTS AND DRIVING RISKThis study compared the driving records of 106,214 persons arrested for drug offenses in 1989 with 41,493 comparison drivers drawn from the general driving population. The drug arrestees were grouped according to the six summary offense categories used by the Department of Justice (DOJ), which were felony narcotics, marijuana, dangerous drugs, and other drugs, and misdemeanor marijuana and other drugs. Time periods examined were 1 year pre-arrest, 1 year post-arrest and 2 years post-arrest. Each drug arrestee group had significantly more traffic violations and total accidents than the control group, except for 2 year post-arrest accidents for the felony narcotics group. Measures of accident culpability showed drug arrestees to be more responsible for the accidents in which they were involved than was the general driving population. Individuals arrested for drug offenses clearly pose an elevated traffic safety risk. These findings provide a public safety justification for state and federal initiatives designed to institute driver licensing actions against drug offenders, and support for the implementation of Public Law 101-516 in California. |

Teen and Senior Drivers – Report 141This report updates information on teen and senior drivers published in earlier California Department of Motor Vehicles' reports. Teen Driver Facts (Huston, 1986), Senior Driver Facts (Huston & Janke, 1986), and Teen and Senior Drivers (romanowicz & Gebers, 1990). The information is meant to assist Highway safety administrators in making program and policy decisions affecting teen and senior drivers, and may also be of use to the insurance industry, traffic safety researchers, and the general public. The report also summarizes research on risk-taking and alcohol consumption among teen drivers and on the increase in impairment of driving-related abilities among senior driers. Countermeasures for teen and senior drivers are also discussed. |
