What to do first
Make sure everyone is safe. If anyone is injured, or the vehicle is blocking a live carriageway, call 999 before you call anyone else. On a busy London road, getting people away from moving traffic matters more than anything to do with the car.
Then exchange details with the other driver if it is safe to do so, and photograph the vehicles, the damage, the position of both cars and anything relevant nearby — road markings, signage, the junction. In a city these details settle arguments about fault later, and they are much harder to reconstruct once the vehicles have moved.
Then call us. Tell us where you are, what has happened and whether the vehicle can be driven. We will work out what needs to happen from there.
