North Carolina RADAR State Practice Exam

Question: 1 / 400

What is the maximum angle you should use when running RADAR?

10 degrees

15 degrees

20 degrees

The maximum angle recommended when operating RADAR is typically around 20 degrees. Utilizing this angle is crucial because it balances the need for a reliable measurement while minimizing the potential for errors due to geometry and the curvature of the radar beam.

When the angle exceeds 20 degrees, measurements tend to become less accurate. At steeper angles, RADAR can reflect signals off of objects other than the target vehicle, leading to potential misinterpretations or inconsistencies in speed readings.

Staying within the 20-degree limit helps ensure that the radar system is aimed correctly and captures the intended target with greater precision. This understanding is vital for anyone involved in traffic enforcement or related activities where accurate speed measurements are critical.
