The heatmaps represents the density of the incident type in a particular area.
Areas shaded red have a high occurrence of the selected incident.
Areas shaded yellow or green have some occurrences of the selected incident.
Areas not shaded have no recorded incidents of the selected type.
The heatmaps shows the last 25,000 incidents of the selected type.
However, CHPmap.com only started collecting CHP incident data in December 2016, so some categories have significantly less than 25,000 incidents.
The oldest recorded incident for the selected incident type is shown at the bottom of the heatmap.

Although the service tries its best, CHPmap.com is presented with no warranty or guarantee of accurate information.
Incidents you may be familiar with may not show up on the map for three main reasons:
1. CHP occasionally does not specify a unique ID for a posted incident, making it difficult for a computer to track.
2. CHP does not publicly post about traffic incidents that involve criminal activity.
3. Although rare, the data feed from CHP may be subject to unannounced downtime.
If you try to scrape the content of CHPmap.com with a computer program, you will be banned.
CHP stands for California Highway Patrol.
