If in the future there begin to be more of those sorts of problems at that intersection, like if there are more than three accidents within a month, that usually means the intersection itself isn't properly signed (like with four-way stop signs) or the traffic light cycle is off. Or that there's never any patrol coverage to make people slow down and follow traffic code. If that were to happen, you can call your local police department's traffic division and tell them there's a problem intersection nearby and ask that they do a quick "traffic study" that should help identify and solve the problem. That's one of the good things they do with our tax dollars that helps save lives!
