North Carolina Radar Operator Recertification Practice Exam

Question: 1 / 400

In what situation might an officer use visual estimates?

Before activating the radar unit

An officer would use visual estimates when no objective measurements, such as those provided by radar, are available. In certain circumstances, such as when the radar unit has not yet been activated or is not functioning properly, the officer needs to assess vehicle speed and other traffic conditions based on visual observation.

Making visual estimates allows officers to gauge the flow of traffic and identify speeding or erratic driving behavior without relying solely on electronic devices. This skill is essential as it enables law enforcement to maintain traffic safety, even in situations where technology cannot provide assistance.

While the other contexts listed relate to the use of radar or operational conditions, they do not align with the specific scenario where an officer would turn to visual estimates for speed assessment.
