Get to safety and obtain care
Call for appropriate help and avoid remaining in an active traffic area when movement is possible and safe. Keep the emergency and medical documents you receive.
Document the full scene
Photograph approaches, signs, markings, lighting, visibility, nearby cameras, vehicle positions, and bicycle or safety equipment. Save witness information and the official report number.
Avoid early assumptions
Traffic rules, road design, vehicle conduct, visibility, comparative responsibility, and possible public-body procedures require fact-specific review.
