Which method can enhance the accuracy of speed detection?

Using visual estimation in conjunction with speed readings enhances the accuracy of speed detection because it allows the operator to corroborate the data obtained from the speed detection device. When an operator uses radar or another speed detection technology, the readings can sometimes be influenced by environmental factors, device calibration, or other variables. By incorporating visual estimation, the operator can compare the speed measurement against their own observation of the vehicle's speed relative to other vehicles or stationary landmarks. This dual method can identify any discrepancies between observed speed and the radar reading, therefore increasing overall accuracy.

Visual estimation is particularly useful in scenarios where the detection device might have limitations due to obstructions or the dynamics of the road environment. Furthermore, this combination showcases a more thorough approach to speed enforcement, reinforcing the reliability of the data used in traffic stops or citations.
