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.

45.1 | 1974/ 01 |
An Abstract of An Evaluation of Some Additional Factors Influencing the Effectiveness of Warning LettersTo determine the effectiveness of two types of warning letters and an informational pamphlet in reducing the subsequent collision and conviction records of pre-negligent drivers. An additional study objective was to determine the effectiveness of a fo llow-up reinforcement letter se nt to collision- and conviction-free drivers. These hypotheses were suggested by an earlier warning letter study (McBride & Peck, Report #30). This study was designed to attempt replication of the previous results. |

83.1 | 1982/ 09 |
An Abstract of An Evaluation of the Alcohol Reexamination Program for Drivers with Two Major Traffic ConvictionsTo evaluate the traffic safety impact of a reexamination designed to detect and treat drunk driving among drivers with two "major violations" who have escaped license sanctions and other countermeasures. Major violations comprise the more serious traffic violations including reckless driving, hit-and-run, and driving under the influence of alcohol or drugs (DUI). |
