Step 1
Fix the exact location and movement sequence
Record the roadway, intersection, driveway, lane, direction of travel, turn path, traffic control, and where each vehicle came to rest. A useful sequence identifies what each driver was doing before impact instead of reducing the crash to a label.
- Mark the travel direction and lane for every involved vehicle.
- Note turn signals, brake lights, traffic signals, signs, and lane markings.
- Separate what a witness actually saw from later assumptions about speed or fault.
