What is a traffic sketch?

A traffic sketch is a top-down drawing of a road incident: the roads, the vehicles involved, their direction of travel, the point of impact and the key measurements.

How do I draw a traffic sketch online?

Open the free sketch tool, pick a roadway template or build the road layout, place the vehicles, add arrows for the direction of travel, mark the point of impact and note the measurements. When you finish, export the sketch as a PNG image or a PDF report.

Is a traffic sketch useful for an insurance claim or police report?

A clear diagram helps adjusters and officers understand the scene, and some claim forms ask for one. A sketch made here is illustrative: measurements are not forensic and must be verified independently, as the exported report states.
