If you can get the prosecutor to reduce the speed to 10 mph, your fine would be reduced to $175. Otherwise, you will have to talk to the prosecutor about other options. Some jurisdictions offer a community service program. For instance, in Fulton County, subject to meeting the qualifications for the program, you can do 20 hours of community service in lieu of paying a fine, or you can go to an approved defensive driving course and get the ticket dismissed altogether. Also, if you cannot pay all of the fine at once, most jurisdictions offer time to pay. They put you on probation until you pay your fine in full.
