Quoting *~Bunny~Hump~*:" I'm sur e this varies by state, but I have a major problem with speeding, it's not even extreme speeding, ... [snip!] ... a 3 point reduction, just haven'tdone it yet.. they can't make you take drivers ed and your whole drivers test over can they?"
I'd stop speeding if I got that many points.
And it's possible they can make you take your whole drivers test again, I don't know about driver's ed but they may make you take some kind of driving course, but you said you already took defensive driving.
I would just stop speeding and send your certificate in to get the point reduction, but like I said it's totally possible to lose your license and have to re-test to get your license back.
