I stopped at traffic lights on my way to work and my foot slipped of the break and I rolled forwards and bumped the car in front (not a major bump), there was no damage to either cars and the driver in front drove off down the motorway so I carried on with my journey only to find that he had pulled over further down the motorway by which time I couldn't stop as it would have been dangerous for me and other people. What should I do? It has knocked my confidence, have been shaking all day and I am scared that the police are going to turn up and arrest me (I always fear the worst). Anyhow what should I do now, should I go and report it to the police saying that i was in a bump with a car couldn't stop as it was unsafe but here are my details if he gets in touch?
