You'd think it would be easy. Green = go. Red = stop. So many times though I've seen people who take off when their light is still red. I saw another one recently. We were all waiting at the lights, and the left-turn lane remained a red arrow whilst the straight-ahead lanes went green. The car in the front of the left-turn lane obviously saw the rest of the lights go green, and ignored his red arrow. As he turned across the now-oncoming traffic, a particularly quick driver on the other side t-boned him and closed the intersection.
Wonder if he'll used "colour blind" as the excuse for turning through a red light?
