In North Carolina, what is the maximum angle allowed between the RADAR and the target vehicle in stationary mode?

In North Carolina, the maximum angle allowed between the RADAR unit and the target vehicle in stationary mode is 20 degrees. This specific angle is significant because it ensures an accurate determination of the vehicle's speed. When the RADAR is aligned within a certain range, the measurements it takes are more reliable, reducing the chances of errors caused by the angle of reflection.

If the angle exceeds this limit, the accuracy of the speed reading may be compromised due to the potential for radar bounce and the Doppler effect being affected negatively. Hence, maintaining a 20-degree maximum allows law enforcement to effectively use RADAR technology for speed enforcement, ensuring that readings are correct and defensible in court.
