"In the defensive driving world, we say, "the green light anticipator met the red light procrastinator." The collision of these two is usually a "T-bone" - where the two vehicles meet at a 90 degree angle. It's not a "nice" collision. The typical speed through an intersection is over 50 mph! You'd find this is one of the most commonly fatal collisions - one in which seat belts and normal rear-firing air bags won't help you much."
"Be careful around intersections. If you get a yellow light, stop. You can anticipate when the light is about to change, so it is no excuse to say it was too late. If you have the green light, watch for the red-light runner—look left, right, then left AGAIN to make sure the intersection is going to be safe before you enter it, even on one-way streets (because somebody might be going the wrong way AND running red lights). Red light runners are often speeding as well, so make sure you look down the road far enough to see them coming."
I've been a victim of just such a red-light t-bone. It was no fun. Another foot or two forward and I probably wouldn't be here.
