Speeding Fine Appeal United States — How to Fight and Win
Governing legislation: State traffic codes (varies by state)
Speeding fines in the US are governed by individual state traffic codes. There is no federal speeding law — each state sets its own limits and enforcement procedures.
Key grounds for challenging a US speeding ticket include: radar/lidar calibration errors (request maintenance and calibration logs); pacing errors (officer estimation of speed); improper speed limit signs or zone markings; and procedural errors in the citation itself.
In most states, you have the right to request a hearing before a traffic court judge. At the hearing, the citing officer must appear and present evidence. If the officer does not appear, the case is typically dismissed.
Speed traps — areas where limits are unusually low or enforcement is purely revenue-motivated — have been challenged successfully in some states. Some states require minimum lane distances for radar enforcement.

Can I challenge radar calibration in the US?
Yes. Request the radar device calibration records via discovery. Many states require that calibration be performed within a set period — if not, evidence may be suppressed.
What happens if the officer doesn't show?
In most US jurisdictions, if the issuing officer fails to appear at your hearing, the case is automatically dismissed.
What is a "speed trap"?
A speed trap typically refers to an area where the speed limit drops sharply and enforcement is concentrated. Some states have laws limiting speed trap practices, particularly where revenue generation appears to be the primary motive.
