In this country, traffic laws are enacted and enforced by the jurisdiction of which the roads are found. If an infraction occurs in a county, the ticket will be adjudicated in the county. The same is true for an infraction that takes place in a city. In modern times, many jurisdictions within a state match, to varying degrees, the Uniform Vehicle Code, a privately prepared set of traffic laws. However, there are a number of violations that have federal standards that are enforced by the states and counties, and states generally have uniform standards for driving records or use uniform points systems that apply to all licensed drivers. When you receive a traffic ticket, you must read the instructions on the ticket carefully and follow them closely. They will tell you how and when to respond to your ticket. If you wish to defend yourself against those charges, you must do so in the traffic court of that jurisdiction, whether it is a city or county court.
