The Field Manual is a lighter version of the User Manual. The Field Manual does not contain screenshots of the ACRS screens; it's purpose is to guide the officer who may have a question about a specific topic.

For example, all the state drop-downs are included and explained. This field also includes Canadian Provinces and some Caribbean territories. It also explains what to do in the rare event that a crash participant is from a locale not covered by the State drop-down.

This user manual reflects the latest changes to the Automated Crash Reporting System and has a revision date of September, 2017.


The Model Minimum Uniform Crash Criteria Guideline (MMUCC) is a minimum, standardized data set for describing motor vehicle crashes and the vehicles, persons and environment involved. The Guideline is designed to generate the information necessary to improve highway safety within each state and nationally. This data set, originally published in the MMUCC Guideline, 1st Edition (1998), has been revised three times, most recently in the 5th Edition (2017), in response to emerging highway safety issues.

The purpose of this American National Standard is to provide a common language for reporters, classifiers, analysts and users of traffic crash data. The Manual on Classification of Motor Vehicle Traffic Crashes and its predecessor, Uniform Definitions of Motor Vehicle Accidents, have provided classification assistance for more than half a century.

The Manual is designed to facilitate the development of data on crashes involving motor vehicles and other road vehicles in and out of traffic. It is a standard for statistical classifications of motor vehicle traffic crashes for nationwide use.

The principal changes in this Eighth Edition are the incorporation of new definitions/classifications and a number of modifications to existing definitions/classifications (see “Eighth Edition Revised and New D16.1 Definitions” chart on page v.)

Pedestrians are one of the most at-risk groups of roadway users. While they account for only 3 percent of all Americans involved in traffic crashes, they represent 14 percent of all traffic fatalities. Pedestrian safety remains a significant traffic safety issue, and in the past three years, pedestrian fatality numbers have been increasing. This NHTSA publication accompanies the Pedestrian Enforcement Seminar and serves as a guide to developing pedestrian enforcement strategies and programs.
