I used Safety-USA, and it was pretty simple, but a bit time consuming. You could probably knock it out in a couple afternoons when you have nothing better to do. It was mostly comprised of little video clips with an immediate short quiz of what you just saw. Easy. I’ve taken traffic school twice online, and everything worked out fine in terms of settling my ticket and insurance. I guess I have a bit of a lead foot ;) I got my ticket in Placer County, but I remember them mailing me a list of accepted schools with my fine.
