When using stationary radar, what is crucial for accuracy?

Ensuring that the radar is calibrated is critical for accuracy when using stationary radar. Calibration involves adjusting the radar system to align with known standards, which helps ensure that the speed measurements it provides are accurate and reliable. If the radar is not calibrated correctly, it may display incorrect speeds, leading to potential inaccuracies in enforcement actions and traffic data.

Each radar unit has specific calibration procedures, and following these procedures ensures that the device is functioning properly. This process also involves checking for any malfunctions or drift that may occur due to environmental factors or wear and tear over time, which can affect the radar's performance. Accurately calibrated radar systems provide law enforcement officials with the confidence needed to enforce speed limits effectively.

Positioning the radar at different angles, monitoring multiple lanes of traffic, and using handheld devices, while important in their own rights, do not have the same level of direct impact on the fundamental accuracy of the radar's speed readings as calibration does. Proper calibration acts as the foundation for all other operational practices and ensures that the readings obtained are trustworthy.
