When all of the states collect the same basic data about crashes, researchers get a much more useful state-by-state and nationwide picture of driver behavior and vehicle safety. And that helps us design more effective safety programs.
One important tool for improving the accuracy and consistency of data for all types of motor vehicle crashes is the Model Minimum Uniform Crash Criteria (MMUCC) Guideline, a voluntary set of standards that helps the states decide what information to collect at the scene of a crash. And on Monday, the Governors Highway Safety Association (GHSA) released the 4th edition of the MMUCC, developed with funding from our National Highway Traffic Safety Administration.
