No. 1
At the scene
Safety first and paperwork second, but do not skip the paperwork, because almost everything that becomes difficult later becomes difficult for want of something that took ninety seconds at the scene.
- Get clear of traffic if the car moves and it is safe to move it.
- Call it in. An incident or crash report number is the single most useful reference you can hold, and a not-at-fault claim without one is harder.
- Photograph more than the damage. Both cars, both plates, the position of the vehicles, the road, the signage, the weather and the light.
- Exchange and record names, policy numbers, insurer names and telephone numbers. Photograph the other driver’s documents rather than copying them out.
- Do not discuss fault. Not because it is a trick, but because you do not yet know what happened, and neither does anybody else.
