Contributing Circumstances Codes



Accident Contributing Circumstances Guide

Understanding your North Carolina Crash Report or DMV-349 requires interpreting the official North Carolina Division of Motor Vehicle codes. This code protocol was created by the NC DMV to assist investigating officers in gathering a large volume of information from any accident scene and processing that data into a manageable format. Your North Carolina Crash Report cannot be interpreted or understood without knowing the code protocol. This guide will provide you with official codes related to the “Contributing Circumstances” boxes No. 14 – 19. By comparing all numbers entered on your accident report in boxes No. 14 – 19 to the corresponding numbers contained in this guide, you may be able to gain a deeper understanding as to whose actions the officer determined to be the cause of the accident.

The investigating officer’s opinion of who caused the accident is possibly the most important information in your case. Please do not proceed any further with your claim unless you are certain that you completely understand the mechanics of this information and how it relates to your claim.
