Any one who tells you that traffic school is great is lying to you. However this online school is pretty straightforward. No tricks or traps. Just the basic stuff you need to make the DMV happy. I think just about everyone takes this school on line now rather than attending a school in person as it is more convenient and less expensive.
One thing you will need to do is call up the DMV a couple of weeks after you take the school to make sure they got the information. Unfortunately the DMV DOES NOT make this info available online. The only way can be sure they got it is to call them.
