A potential reason for a RADAR unit to fail in detecting a vehicle is indeed related to poor weather conditions. Weather elements such as rain, snow, fog, or heavy winds can interfere with the RADAR signals. These conditions can scatter or absorb the radar waves, reducing the unit's effectiveness in accurately detecting moving vehicles. This aspect of RADAR operation emphasizes the importance of environmental factors in speed enforcement technology.

While camouflaged vehicles and non-standard shapes could theoretically affect detection, they are typically less influential than the direct interference caused by adverse weather conditions. Additionally, vehicles traveling too fast may not be detected due to limitations in the RADAR unit’s tracking capabilities, but it is not as primary a reason as the impact of weather. Thus, the influence of weather on RADAR detection is a critical consideration for law enforcement officers utilizing this technology.
