Which element is NOT part of the radar tracking history process?

The element that is not part of the radar tracking history process is the driver observation report. Radar tracking history typically involves collecting and analyzing data related to the speed of a target, such as visual estimation of target speed, target speed display, and patrol speed verification.

Visual estimation of target speed allows officers to compare their observations with the radar's readings. The target speed display shows the speed measured by the radar, providing real-time data on how fast the target vehicle is moving. Patrol speed verification involves confirming that the radar equipment is accurately measuring speeds in relation to the officer’s own speed, ensuring the reliability of the data collected.

In contrast, a driver observation report is not a direct element of the radar tracking history process. While it can be informative in terms of context and specific interactions with the driver, it does not directly contribute to the process of tracking and recording the speed of a target as measured by the radar system. Instead, it serves as supplementary information that can aid in understanding the circumstances surrounding a traffic stop.
