Probably a lot. You doubled the speed limit.
A speeding ticket for doing 83 miles per hour in a 65 mile per hour zone is between $180 - $210. By attending drivers training the fine will be reduced $30.
72mph = 116km/h
55mph
Unless you are personally served with the ticket by a process server, a complaint (here in the form of a traffic ticket) mailed to you is not proper service. You can ignore the ticket, unless a process server letter serves you with it (in which case you are then obligated to appear at the specified date & time). * There is no need to be "officially served" citation for a traffic violation, nor will it happen. The citation may or may not be sent by certified mail, irregardless it is a valid ticket and should be handled according to the enclosed directions. Fines for traffic violations are set by state law. Therefore, without knowing the state in which the incident occurred there can be no specific answer. Contacting the clerk of the traffic court in the city or county where the ticket is issued will obtain specific information.
