Rachel, it's almost always worth it to go to court instead of merely sending in the money for the fine.........if nothing else, the judge may very well reduce the amount you have to pay, especially since it's your "first offense" so to speak. And frankly, it sounds to me like you might want to fight the ticket---you say you were going about 60 MPH in a 45 MPH zone, which definitely makes you guilty of speeding, but the cop said you were doing almost 70, and that can be pretty serious in the eyes of the law (not to mention your insurance company
However, what this does is call into question the ability of the officer to clock your actual speed correctly. Do you know how he caught you?---e.g., did he use radar/laser, did he pace you, how did he determine your speed? Also ask yourself, what were the road and weather conditions like? Was it sunny and dry? Is 45 MPH in that particular zone even a reasonable speed, or is the area more like a highway, with more than one lane in each direction and lots of open road? (There ARE such things as speed traps, ya know.)
These are only a few of the elements of a speeding charge, and if there's any question in your mind at all that you did what the officer says you did, you should take the time to fight it. I know several people who have successfully won traffic cases (not me, though---I'm one of those who goes 20 years between speeding tickets, and then when I DO get nailed, I get nailed big time), and there are even books and websites devoted to fighting traffic tickets. Seeing as how most "violations" are about raising revenue for the city or county, rather than protecting the public, it's worth trying, and it may save you some points on your license and increased car insurance rates for up to three years.
I'll be with you in spirit.........meanwhile, I've got this unregistered-vehicle citation I need to contest..........
