In February 2005, AAMVA convened a working group comprised of motor vehicle agency representatives, law enforcement professionals, judges, prosecutors, researchers and highway safety professionals from NHTSA, FHWA and FMCSA to develop a needs assessment to address the problem of driving while suspended. The working group determined that not enough was known about the depth and breadth of the issue and that research was needed to more fully understand the changing relationship between license suspension, reasons for suspension and highway safety outcomes. This study was commissioned in response to the working group's call for additional research. The research objectives defined for this study included, determining the number of drivers that are suspended/revoked under state laws that allow a driver's license to be suspended/revoked for non-driving offenses; determining the number of those drivers that are subsequently cited for driving while suspended, determining the extent of crash involvement by those drivers; and exploring the relationship between driving behavior and violations of those laws. The analysis conducted for this study provides a baseline for further discussion by the AAMVA suspended/revoked driver working group. The research results point to differences between the two groups when considering driving behavior. Overall, the analysis provides information to administrators and safety experts indicating the two groups of suspend drivers differ on multiple dimensions.
