“Mr Tatner does not dispute that he drove negligently, in that he failed to brake in time to avoid colliding with the vehicle in front of him.”
“That had the consequence that he came to a halt nearer to the traffic behind than he would have done had he managed to brake and not collide with the vehicle in front.”
“Mr Tatner would not have been regarded as driving negligently had he come to an emergency stop in sufficient time to have avoided colliding with the vehicle in front.”
