There is a little-known statute that helps to prevent police officers (excluding Georgia State Patrol) from establishing speed traps (i.e. being positioned behind trees, etc.) by requiring that their vehicles are visible to YOU at a distance of at least 500 feet.
We may be able to have radar evidence thrown out pursuant to O.C.G.A. § 40-14-7, which requires that no stationary speed detection device be used by county, municipal, college or university law enforcement when the patrol vehicle utilizing the speed detection device is obstructed from the view of approaching motorists or is not otherwise visible for a distance of at least 500 feet (almost a length of two football fields). In speeding prosecution, the State must show that the speed detection device was visible to an approaching motorist before evidence gained by a speed detection device can be admissible. Carver v. State, 1993, 208 Ga.App. 405, 430 S.E.2d 790. However, the statute makes no exception for night hours but we may have a strong argument if the patrol car’s headlights were not on as you approached.
