About My Traffic Sketch
My Traffic Sketch is a free, multilingual browser tool for creating clear illustrative traffic collision diagrams, with a set of guides and worked examples written around it.
Why this tool exists
My Traffic Sketch was started by someone who has to make collision diagrams for reports again and again. Drawing them by hand or in a paint program was slow and the result was hard to read, and the free online sketch site they had been using went offline. The goal is a tool that does that job quickly, and that any driver can use for an insurance claim or a police report, without expensive software, an account, or a desktop CAD program.
So the editor runs entirely in the browser, saves the draft locally on the device, and exports a single-page report with the diagram, the vehicle table, the narrative and a legend. No sign-up, no upload, no watermark.
What the editor covers
The editor is built for drivers and anyone who needs a clean diagram for a report or claim. Road templates, photo tracing, auto-numbered vehicles, plates, arrows, measurements in feet or meters, a compass and a scale bar cover the common cases; everything else can be drawn by hand.
How these pages are made
The text on this site, including the guides, articles and worked examples, is drafted with AI assistance. The diagrams in the guides and the worked examples were made in this site's editor.
Each article and the worked-examples page states whether the site operator has reviewed it, and on what date. A page marked "Not yet reviewed by the site operator" has not yet been read and approved by the operator.
The example scenarios are fictional, and their plates, positions and distances are invented for teaching. When an example includes a number (a skid length, a distance to an impact point), it is labeled illustrative: a real diagram records what you actually measured.
Articles show a publication date and, when a piece is materially revised, a visible updated date.
Principles
- ▸Illustrative measurements are always labeled as illustrative, never presented as verified.
- ▸Diagrams document geometry and observation; they never assign fault or draw legal conclusions.
- ▸This site never fabricates official requirements. Agency, insurer and jurisdiction rules always take precedence over anything on this site.
- ▸Fictional example data (plates, names, distances) is identified as fictional.
Privacy-minded by default
No account is required. Drafts are stored locally in the browser so users remain in control of their working copy. Nothing you draw is uploaded to us. Export the PDF or PNG when you finish; that file is your record.
Free, and meant to be ad-supported
My Traffic Sketch is free to use. The site intends to be supported by Google ads, but it shows no ads today.
Who runs this site
My Traffic Sketch is an independent project, not a company, a government agency or an insurer, and it is not affiliated with any police department. The site does not sell the drawings or the data you enter.
