Step 1: Check for injuries and call 911 if anyone is hurt. This is non-negotiable. Even if injuries seem minor, call. Adrenaline masks soft-tissue injuries that show up the next day. If you're rear-ended, neck and back symptoms can take 24-72 hours to fully appear. Police presence also creates a contemporaneous record of the scene that's invaluable later. Arizona requires drivers to report accidents involving injury or death under ARS §28-667; for damage-only minor accidents, Phoenix-area department response policies vary and many deprioritize minor no-injury collisions, but officers will typically still document the incident if you call.
Step 2: Move vehicles out of traffic if drivable. Arizona's "quick clearance" law (ARS §28-674) explicitly protects you from being held at fault solely for moving a drivable vehicle off the main roadway before police arrive. Hazard lights on. Triangles or flares if you have them. Don't stand between vehicles — secondary collisions kill more people than primary collisions. Get yourself and passengers to a safe spot off the road.
Step 3: Document everything with photos. Before vehicles get moved (if you have time), photograph: damage to all vehicles from multiple angles, license plates, insurance cards (yours and theirs), driver's licenses, the position of the cars on the road, any skid marks or debris, the street signs and traffic signals, and the road and weather conditions. Take 30+ photos. Storage is free; lost evidence is expensive.
Step 4: Exchange information. Get the other driver's full name, phone, address, insurance company, policy number, vehicle license plate, vehicle VIN if accessible, and driver's license number. Photograph their insurance card and license. If there are witnesses, get their phone numbers — witness statements are gold in disputed-fault cases. Don't accept the other driver's offer to 'just settle this without insurance' — these offers almost always shortchange you and you have no recourse later.
Step 5: What NOT to say at the scene. Don't admit fault. Don't apologize ('I'm sorry' can be used as an admission). Don't speculate about what happened ('I think I might have been going a little fast'). Don't accept any blame, even partial. Stick to facts: 'I was traveling north on Center Street. The other driver came from the east on Main.' Let the insurance companies determine fault from the evidence — that's literally their job.
Step 6: File the claim and get to a body shop. Call your insurance carrier or use their app to start the claim. Most issue a claim number within 10 minutes by phone. If you weren't at fault, you can file with the other driver's carrier instead — they pay the full repair plus rental with no deductible. Bring the claim number, your insurance card, and registration to Orlando Auto Body or any reputable shop. Arizona law (ARS §20-468) gives you the right to choose any licensed shop; you are NOT required to use the insurer's recommended shop.
