Coming across a crash is frightening, and the instinct is to rush in and help. But the safest, most useful thing you can do follows a calm order — because a rescuer who becomes a second casualty helps no one.
The order is: protect, then alert, then aid. First make the scene safe — switch on your hazard lights, stop well clear, and warn other traffic so there isn't a second collision. Then alert the emergency services with a clear 999 call. Only then do you help the people involved, as far as you safely can.
Telling the services where you are and what's happened matters more than anything heroic. Location, how many vehicles, whether anyone's trapped or not breathing — that information is what brings the right help fast.
The bits that matter
- Work in order: protect the scene, alert the services, then aid casualties.
- Make it safe first — hazard lights, stop clear, warn other traffic.
- A clear 999 call with the location is the most valuable thing you can do.
Memory anchor
Protect, alert, aid
Three steps, always in this order: Protect the scene so no one else crashes, Alert the emergency services with a clear call, then Aid the people as best you safely can. Protect, alert, aid — rushing straight to "aid" is how rescuers get hurt.
Out on the road
The crash on the bend
You come round a bend to a crash just out of sight of approaching traffic. Before anything else, you stop safely, put your hazards on and warn the cars coming behind — because a second crash into the scene is the real danger. Then you call 999. Making it safe first protected everyone, including you.
The mistake everyone makes
Running into the road to help
The most natural thing — sprinting to the casualties — is also how first responders get hit by traffic. Make the scene safe and call for help before you step into danger. You can only help people if you don't become a casualty yourself.
