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.

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. |
