Which of the following must be demonstrated during the training course?

In the context of a RADAR operator training course, the ability to estimate vehicular speed is essential because the primary function of a RADAR operator is to measure the speed of moving vehicles. Understanding how to accurately determine speed using RADAR technology is a critical skill; it involves interpreting the readouts from the RADAR device and applying that information in situational contexts, such as traffic enforcement. Mastery of this skill ensures that officers can correctly identify violators and enforce speed limits effectively, thereby contributing to road safety.

While skills like writing reports, operating a patrol vehicle, and conducting interviews are valuable in overall law enforcement, they do not specifically pertain to the unique responsibilities of a RADAR operator during training. The focus on speed estimation highlights the specialized training required to use RADAR equipment correctly in various traffic situations.
