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 Young Driver Follow-up Study: An Evaluation of the Role of Human Factors in the First Four Years of Driving
To collect biographical and driving-record data in order to provide evidence for evaluating three approaches to reducing the high accident rate among teenagers: (1) raising the licensing age to 18; (2) identifying the "accident prone" driver; and (3) improving driving via formal driving education and training.
