Deliberately induced road collisions (‘crash for cash’) are on the increase, apparently. Criminals cause a crash typically by braking hard and unexpectedly in front of the victim’s vehicle, and profit from the resulting claim for damage and personal injury.
This dangerous and illegal practice exploits the fact that the victim cannot stop in time to avoid hitting the vehicle in front. In other words, it can only succeed when the victim is driving in an unsafe manner. As Rule 126 of The Official Highway Code says:
Drive at a speed that will allow you to stop well within the distance you can see to be clear.
If all motorists obeyed this rule perhaps there would be no incidents of ‘crash for cash’.
