At what distances is it critical to confirm the accuracy of LIDAR equipment?

The importance of confirming the accuracy of LIDAR equipment primarily revolves around its effectiveness in measuring distances accurately, particularly in a dynamic environment such as traffic enforcement or accident reconstruction. The correct answer identifies the distances of 50, 100, and 150 feet as critical points for verification.

At these distances, LIDAR systems are typically positioned in a way that allows them to achieve optimal accuracy within the range of traffic regulation and monitoring. The distances chosen reflect scenarios that are most relevant for law enforcement purposes, where precision is vital. For example, at 50 feet, you'd expect to confirm the immediate accuracy of the LIDAR readout, especially since these measurements can directly influence the outcomes of traffic stops or citations.

As the distance increases to 100 and then 150 feet, the potential for measurement errors can equally rise due to factors such as environmental conditions, the angle of the measurement, or the calibration of the device itself. LIDAR is particularly sensitive to these aspects, so confirming its accuracy at these specified ranges ensures reliable operation and helps maintain the integrity of law enforcement practices or any application where precise measurements are required.

The other distances presented in the remaining choices do not align with the typical concern thresholds established for effective LIDAR verification.
