What role do weather conditions play in speed measurement?

Weather conditions significantly influence speed measurement values, which is why they can distort the accuracy of these readings. Various weather factors, such as rain, fog, snow, or even high winds, can affect the performance of the speed detection equipment and the visibility conditions under which officers operate. For instance, rain can lead to reduced tire-road traction and may also cause water splatter that interferes with radar or lidar signals. Similarly, fog can limit visibility, affecting both the officer's ability to monitor traffic and the effectiveness of speed enforcement equipment.

In contrast, the other options imply that weather conditions are inconsequential, enhance accuracy, or are only relevant to certain vehicle types, which overlooks the impact that external environmental factors have on both the speed measurement process and the interpretation of the data collected. Thus, understanding how weather conditions can distort speed measurement values is essential for ensuring proper enforcement and interpreting speed measurements accurately.
