21658(A) is a moving violation and goes on your driving record as a point. As mentioned above you can attend traffic school if your eligible. If you've attended traffic school within the last 18 months you're not eligible. Also if you contest the ticket and are found guilty, you're ineligible to attend traffic school.
Basically anything you do driving will go on your record as a point. There are some like seatbelts and other equipment violations that go on your record but not as as point. Then there are correctable violations which as long as you take care of them and don't FTA on them, won't go on your record at all.
A general rule of thumb is if you do something while driving...that's gonna be a point on your record.
Be advised, I'm mean nasty and tired. I eat concertina wire and piss napalm and I could put a round through a fleas *** at 300 yards. So why don't you hump somebody else's leg mutt-face before I push yours in.
