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 Traffic Safety Impact of Driver Improvement Countermeasures Targeting 55-MPH Speed Limit ComplianceThe overall objectives of this study were twofold: (1) to evaluate a speed-oriented home instruction/point reduction incentive program (HI/PRI) and a speed education meeting (SEM) as alternatives to the group educational meeting (GEM) for negligent operators, and (2) to evaluate the effects of a modified speed compliance HI/PRI program on repeat speed offenders. |

The Long-Term Traffic Safety Impact of Pilot Alcohol Abuse Treatment as an Alternative to License Suspensions (Volume 2 of “An Evaluation of the California Drunk Driving Countermeasure System”)To evaluate the long-term traffic safety effects of participating in a Senate Bill (SB) 330 drunk driver program in lieu of receiving a mandatory license suspension or revocation. |

| 89 | 1984/ 03 |
Analysis of DUI Processing from Arrest Through Post-Conviction Countermeasures (Volume 1 of “An Evaluation of the California Drunk Driving Countermeasure System”)(1) To develop process flow charts for the whole DUI system, depicting all elements and decision points concerning drivers, abstracts, and license actions involved in the reporting system, both before and after new legislation (AB 541) became effective on January I, 1982; (2) to describe the whole DUI system from the point of arrest to the driver record file, both before and after AB 541; (3) to identify areas or sources of system inefficiency or modes of circumvention of specified provisions, especially in the post-AB 541 system; and (4) to develop alternate solutions and associated recommendations. |

Extending Driver Licenses by Mail: A 36-month Follow-Up of Driver RecordsTo evaluate the traffic safety impact of extending driver licenses by mail for drivers with clean prior four-year records. |

| 86 | 1983/ 02 |
The Accident Record of Drivers with Bioptic Telescopic Lenses.To determine whether the accident rate of drivers with bioptic telescopic lenses ("bioptic drivers") was great enough to warrant denying them a license to drive, as a 1982 American Association of Motor Vehicle Administrators resolution recommended. |

| 85 | 1983/ 06 |
Intervention Strategies for Accident-Involved Drivers: An Experimental Evaluation of Current California Policy and AlternativesTo evaluate standard and alternative strategies for selecting and treating accident-involved drivers in California. |

| 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. |

An Evaluation of the Alcohol Reexamination Program for Drivers with Two Major Traffic ConvictionsTo evaluate the traffic safety impact of a reexamination designed to detect and treat drunk driving among drivers with two "major violations" who have escaped license sanctions and other countermeasures.
