Also, on the ticket should be the fine for the speeding infraction. From BB2000's post you should be able to determine how far over the speed limit you were. If you were only 2 kms over the limit, and you can take the time off to dispute the ticket then you stand a good chance. However, do your homework, make sure you find out the speed limit for the area, and the exact spot the cop issued the ticket at. Good luck.
Also, even though some traffic cops won't admit it, some municipalities have a quota system in place. A minimum amount of tickets have to be written up each month. And guess what we are coming up to the end of the month.
