Collision – What Next?

it's legal to undertake when the stationary traffic is moving slower/stopped due to a traffic light or junction. His manoeuvre, while not illegal, was probably initiated by a driver in your lane flashing/waving him on, which is illegal, and this crash is why it is illegal. In short, legally he is in the wrong and you are in the right, aside from the brakeless bit.

Same sort of thing happened to me and both guys (the one who flashed him through and the car that hit me) were liable......but and a big but, The police didn't tell me this infomation, I had to find out myself.
