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.

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 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. |

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. |

THE CALIFORNIA DRIVER PERFORMANCE EVALUATION PROJECT: AN EVALUATION OF THE CURRENT DRIVER LICENSING ROAD TESTThe California DMV is currently involved in a comprehensive effort to increase the competency level of the California driving population. One of these efforts involves the development of a new class C (passenger vehicle) drive test. The present report is designed to provide data on the reliability and psychometric properties of the current class C road test in order to provide a baseline comparison for the new drive test. This evaluation of the current test represents "Stage 1" in a multi-phase test development master plan (Williams & Shumaker, 1994). |

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. |

Diabetes Mellitus and DrivingTo review the literature on insulin-treated diabetes and driving for members of a Medical Advisory Board subcommittee formulating guidelines for DMV Driver Safety in cases of diabetes mellitus. |

AGE-RELATED DISABILITIES THAT MAY IMPAIR DRIVING AND THEIR ASSESSMENTThis review, covering literature on age-related disabilities, their assessment, and their effects on driving, represents the initial step in developing an assessment system for identifying and evaluating the driving competency of older drivers with dementia or age-related frailty. Since frailty can be defined as a result of the combined effect of various pathologies superimposed upon the normal physiological changes of aging, emphasis is given to medical conditions which are more characteristic of elderly people. The relationships of these conditions to driving performance and safety are discussed, and nondriving and driving tests relevant to identifying and licensing frail or dementing elderly are described. There is a brief discussion of licensing and post-licensing control programs for elderly drivers in several jurisdictions, including graded licensing. A preliminary assessment protocol for identifying medically impaired elderly drivers and evaluating their driving ability is suggested. |

THE CALIFORNIA DRIVER PERFORMANCE EVALUATION PROJECT: AN EVALUATION OF A NEW DRIVER LICENSING ROAD TESTIn 1990 the California Department of Motor Vehicles (DMV) initiated a program to increase the level of driving competency of the California driver population. A key element of this program involves the development and implementation of an improved drivetest. |
