The data supports various local, county and state traffic safety programs, engineering and planning projects, legislative concepts, and law enforcement services. Legally reportable motor vehicle traffic crashes are those involving death, bodily injury, damage to personal property in excess of $2,500; or damage to any vehicle over $2500 and any vehicle is towed from the scene as a result of damage (effective 1/1/2018). Drivers are required to file an Accident and Insurance Report Form with DMV within 72 hours of a traffic crash. From 1/1/2004 through 12/31/2016, drivers were required to file a report when damage to the driver's vehicle was over $1,500; damage to any vehicle was over $1,500 and any vehicle was towed from the scene as a result of damage; if injury or death resulted from the accident; or if damage to any one person’s property other than a vehicle involved in the accident was over $1,500. From 9/1/1997 through 12/31/2003, the damage threshold was $1,000. Prior to 9/1/1997, the damage threshold was $500. For more information on filing requirements, please contact Driver and Motor Vehicles Services (DMV). Disclaimer: The Crash Analysis and Reporting Unit is committed to providing the highest quality crash data to customers. However, because submittal of crash report forms is, by statute, the responsibility of the individual driver, the Crash Analysis and Reporting Unit cannot guarantee that all qualifying crashes are represented in the Statewide Crash Data System (CDS), nor can assurances be made that all details pertaining to a single crash are accurate. Database expansion and refinement implemented in 2002 may result in slight differences from data reported in earlier years.
