What is a common outcome of not maintaining proper distance between radar units?

When radar units are not maintained with proper distance from each other, it can lead to inaccurate speed readings. This phenomenon occurs due to a variety of factors, including radio frequency interference and the potential for multiple signals to affect the measurement process. Radar units rely on a clear line of sight and specific conditions to provide accurate speed assessments. If units are positioned too closely, they can influence each other's signals or create confusion in the processing of the speed data. This interference compromises the integrity of the readings, resulting in potential legal and operational repercussions for law enforcement.

The other options do not align with the consequences of improper distance. For example, closer proximity does not enhance speed detection efficiency or simplify the operation of the units. In fact, it complicates both. Additionally, officer safety is not directly improved by placing radar units closer together; it typically necessitates ensuring adequate space for proper function and reducing hazards associated with their operation.
