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.

Teenage Driver Risks and InterventionsCalifornia teenage drivers aged 16-19-years-old have extremely high per capita and mileage-adjusted crash and traffic violation rates. This report summarizes the literature regarding the risk factors involved in their high crash rates, as well as the countermeasures that have been used in California and elsewhere to reduce their high crash risk. Although some portion of teenage crash involvements can be accounted for by poorer basic vehicle handling skills, the research suggests that it is young drivers’ immaturity and inexperience, and the resultant risk-taking, that contribute most to their increased crash risk. Certain driving conditions, such as nighttime driving and transporting young passengers, are particularly high risk for teen drivers. The higher crash rates for teens associated with the use of alcohol and drugs may mostly be the result of a general pattern of risky behavior. The countermeasures used to reduce the crash risk of teen drivers that are discussed in this report include driver improvement programs, driver education and training, special licensing programs for teens (provisional and graduated licensing), BAC limits, and curfew laws. |

Teen and Senior Drivers – Report 240This report updates statistical information on California teen and senior drivers as published in earlier reports prepared by the California Department of Motor Vehicles: Teen Driver Facts (Huston, 1986), Senior Driver Facts (Huston & Janke, 1986), Teen and Senior Drivers (Romanowicz & Gebers, 1990; Gebers, Romanowicz, & McKenzie, 1993; Aizenberg & McKenzie, 1997 [with the Beverly Foundation]; and Janke, Masten, McKenzie, Gebers, & Kelsey, 2003). 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 international research on the driving safety and driving-related abilities of teen and senior drivers, and on crash countermeasures for these two groups. |

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 drivers. Countermeasures for teen and senior drivers are also discussed. |
