Each filter in Crash Query for WVDOT has a prefix. Each of these prefixes is there to aid users in narrowing down their search and focuses specifically on three different categories. These are Crash (C), Crash Factor (CF), Geographic (G), Strategic Highway Safety Plan (SHSP), and Social Vulnerability Index (SVI).

Filters are as follows:

  • C - Crash (pulled from the Crash Report). This prefix helps users narrow their search based on the crash information they wish to focus on. Users can select one of the following to help refine their searches utilizing the prefix (C).

  • CF - Crash Factor. This prefix narrows down the filtering to the circumstances surrounding the crash.

    • Event - the circumstances of the crash
