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.

California Vehicle Registrations and Driver Licenses – 1946-1961To produce an extension of the 1959 Department of Motor Vehicles report titled "California Vehicle Registrations and Drivers Licenses, 1946-1958" (Research Report No.1) for the years 1959, 1960, and 1961. The report should be useful as a basic set of historical statistical information regarding California vehicle registrations and drivers' licenses. |

The Totally Deaf Driver in California, Part ITo determine whether or not the driving records of deaf drivers differ from those of non-deaf drivers, and whether or not deafness or other factors are responsible for any differences found. Specifically, the study was designed to ascertain whether the deaf driver represents a special risk to public safety and, if so, to suggest any necessary licensing restrictions or unique training needs. |

The Totally Deaf Driver in California, Part IITo determine whether or not the driving records of deaf drivers differ from those of non-deaf drivers, and whether or not deafness or other factors are responsible for any differences found. Specifically, the study was designed to ascertain whether the deaf driver represents a special risk to public safety and, if so, to suggest any necessary licensing restrictions or unique training needs. |

A Re-Evaluation of Group Driver Improvement MeetingsThe group approach originally evaluated in 1961 (Coppin, Report #9) was re-evaluated to determine if the program was still effective. Both studies utilized a control group for comparison, although assignment to treatment was not random. Both reports indicated that the approach was an effective means of reducing violations, but there was no evidence of reduced accident frequency. It was recommended that different types of group and individual approaches be tried so that an optimum approach could be developed. It was also recommended that classical experimental design procedures be used in subsequent evaluations, including randomization. |

Driving Under Suspension and Revocation: A Study of Suspended and Revoked Drivers Classified as Negligent OperatorsTo examine a six-year record of 1,326 negligent operators who were suspended or revoked to determine how many continued to drive and how many were convicted of this offense as well as the violation for which they were stopped. |

The Teen-Aged Driver – Report 21To examine the accident and conviction records of teenaged drivers to determine whether or not a change in the licensing age was warranted and whether or not behind-the-wheel driver training was effective in reducing accidents and convictions. |
