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.

NRN020 | 1977/ 09 |
Driver License and Driver Improvement ProgramThe report attempts to conceptualize driver licensing programs into a series of administrative techniques which, if applied in a systematic fashion, should enhance road safety. The basic concept of the report is a recommended shift from a system of selection/ enforcement to a system which is more diagnostic and/or educational in nature. This means a shift from doing things to drivers to a program which operates constructively for drivers. |
