How do weather conditions impact speed detection accuracy?

Weather conditions significantly impact speed detection accuracy by affecting the performance and functioning of the speed detection devices. In adverse weather, such as rain, fog, or snow, the signals used by these devices can be obstructed or scattered. This interference can cause inaccuracies in how the device calculates the speed of moving objects. For instance, rain can create interference with radar signals, leading to readings that may not accurately reflect the true speed of a vehicle. Similarly, fog can diffuse signals, further complicating detection efforts. Understanding this relationship is crucial for operators to maintain the integrity and reliability of speed detection practices under varying environmental conditions.
