The D16.1 is a standard for classifying motor vehicle traffic accidents. The primary purpose of the D16.1 Manual is to promote uniformity and comparability of motor vehicle traffic accident data, being developed and used in states and local jurisdictions. The D16.1 Manual provides a common language for reporters, classifiers, analysts, and users of traffic accident data. D16.1 addresses distinguishing characteristics of motor vehicle traffic accidents to assist officers in determining whether or not an incident is a motor vehicle accident. For example, the officer would have to answer "yes" to each of the following questions, for it to be a motor vehicle accident.
