What is the typical range for radar guns in stationary and moving modes?

• A. 100 feet for both modes
• B. Up to 1,000 feet for stationary and 500 to 1,200 feet for moving radar
• C. Only 500 feet for both modes
• D. 1,000 feet for moving and 500 feet for stationary radar

Answer: (B)

The correct answer describes the typical range capabilities of radar guns when used in different operational modes. For stationary radar, the maximum range can extend up to 1,000 feet, allowing law enforcement officers to capture the speed of vehicles from a considerable distance while remaining in a fixed position. When using moving radar, the effective range can vary between 500 to 1,200 feet, as the radar technology utilizes the motion of both the radar unit and the target vehicle for enhanced accuracy. This range allows officers to monitor traffic effectively while moving, providing a wider scope for speed enforcement and improving road safety.

Understanding these ranges is critical for proper usage and ensuring that speed measurement is conducted within the recognized limits of the device, thereby supporting accurate and enforceable citations.
