Mark the route and exact point of contact
Record direction, lane, crossing, path, driveway, parked vehicles, traffic controls, lighting, weather, obstructions, and where each person first became visible.
Preserve equipment and digital records
Keep the bicycle, helmet, lights, clothing, phone, navigation, fitness, and camera files unchanged. Ask before repairing or discarding damaged items.
Look beyond the nearest driver
Vehicle owners, employers, road or path controllers, construction contractors, property operators, and product companies may require investigation without implying responsibility.
Track medical and functional changes
Document care, restrictions, mobility, work or school effects, transportation changes, damaged property, and replacement expenses with source records.
