whats the problem with actually paying the fine?
i mean...you lose what? 3 points and $150? something like that...i've been busted for speeding (i was pissed off...it was stupid) but there's not much you can do...in the end disputing it'll just be more hassle than its worth...
i was busted once for going through a red light but that's actually coz there were 2 consecutive intersections...with 2 different sets of lights...i entered the 1st just as it turned amber and it turned red just as i entered the 2nd...there was about a 1 or 2 car distance between the 2 intersections and i really honestly didnt know they were separate intersections...there was no collision and nobody was hurt (thank god) but i still wore the fine coz it was driver negligence (mine) that caused it...
the time i was busted for speeding i was doing 75 (actually i think it was 80) on a friday night at 11pm on a 3lane road without a single car around...there was a speed trap and i got caught...i was in the wrong (even though the speed i was doing was by no means dangerous considering the conditions)...i wore the fine...i now have 1 point

and drive carefully
in the end...its not really worth disputing...if yer gonna drive outside the law...either dont get caught...or pay the fines when you do...
