How visible must stationary RADAR vehicles be for proper operation?

For stationary RADAR vehicles to operate correctly, they need to be visible to oncoming traffic from a sufficient distance. This visibility is crucial as it allows drivers to anticipate the presence of the speed detection equipment, thus ensuring the accuracy and fairness of speed enforcement. The standard requirement for visibility is 500 feet. Being visible at this distance provides a clear line of sight for drivers, which can help in reducing the likelihood of unexpected encounters with speed detection devices and can contribute to safer driving behavior as motorists can observe the equipment well in advance. This distance is also in line with many law enforcement agency guidelines to promote transparency and promote traffic safety.
