What Is The Most Dangerous Type Of Moving Violation?

I am wondering what my readers view as the most dangerous type of moving violation. Of course, all of them raise safety issues but I am looking for what you think is the single, most dangerous one.

Personally, my vote goes to disobeying a red light. Motorists rely on a green light in proceeding through intersections and cross traffic motorists that ignore their red lights can lead to very serious “T-bone” accidents.

What do you think? And why?
