Traffic sketch — frequently asked questions
- What is a traffic sketch?
- A traffic sketch (also called a collision diagram, crash diagram or accident scene diagram) 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. Police officers, insurers and drivers use it to document what happened.
- 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 many 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.
- How much does My Traffic Sketch cost?
- Nothing. The tool is free, runs in your browser and requires no account. Your sketch stays on your device — nothing is uploaded to a server.
