What is the distance that RADAR must be from warning signs after exiting a city?

The correct distance that RADAR must be from warning signs when exiting a city is 600 feet. This guideline is important to ensure that RADAR units operate effectively while providing an appropriate buffer zone where drivers are alerted to changes in speed limits or other crucial information. The distance allows enough space for drivers to react to the warning signs, promoting safety as vehicles transition from urban to potentially higher speed areas. Adhering to this distance not only complies with regulatory requirements but also enhances the credibility of the speed enforcement process by ensuring that drivers are adequately informed before entering areas where speed regulations may differ.
