Hey all... need a bit of advice wether I did the right thing. On a road today the car in front of me stopped a bit quick coming up to a round about. So in turn I had to stop pretty quick, and the car behind me. But the car behind me got rear ended. I didnt stop because If I had I would have caused a jam. The two cars behind me had a layby to pull into. Should I have stopped? or is it nothing to do with me as I wasnt hit in any way? opinions?
