Why are subjective observations important in speed enforcement?

Subjective observations are crucial in speed enforcement because they help establish the context surrounding a traffic stop. These observations can include factors such as the behavior of the driver, the conditions of the roadway, and the presence of nearby vehicles or pedestrians. When an officer has recorded a measured speed using a speed detection device, subjective observations can lend credibility and support to that measurement. For example, if a driver is speeding in a school zone during school hours, an officer's observations regarding the traffic conditions, the number of children present, and the driver's erratic driving behavior can all reinforce the necessity for enforcement action.

This context is important not only for legal proceedings, where establishing the justification for the enforcement action may be required, but also for communicating effectively with the driver about the reasons for the stop. By providing a narrative that accompanies the measured speed, officers create a more comprehensive understanding of the situation, ensuring that the rationale for enforcement is clear and well-founded.
