What are the top five traffic violations that cause traffic collisions?

21703 (a) VC – Following too close.
You must follow the vehicle in front of you a distance that allows you to stop, no matter how quickly that vehicle stops. The three (3) second rule will allow you to easily judge this distance. The three second rule indicates that if you see the vehicle in front of you pass a object (i.e. cross walk line, light pole, etc) you should not pass that same object in less than three seconds.

21453 (a) VC – Failing to stop for red signal lights.
California law recently doubled the fine for red light violations.

23152 (a) VC – Driving under the influence of alcohol and/or drugs.

22350 VC – Unsafe Speed
In excess of the posted speed limit (going too fast), or driving at any speed that is unsafe based on the conditions present ie rain or fog. You can be only going 40mph, but if you cant see 10 feet in front of you, then you are going at an unsafe speed.

21801 (a) VC – Left turns.
A driver may not negotiate a left turn when another vehicle is approaching head on, that is so close as to be a hazard.
