What must an officer provide to justify the use of a speed measurement device in court?

To justify the use of a speed measurement device in court, an officer must provide evidence of the device's calibration, maintenance records, and training. This is crucial because the reliability and accuracy of the speed measurement device are essential for upholding the integrity of the evidence presented.

Calibration ensures that the device is functioning correctly and providing accurate measurements. Maintenance records demonstrate that the device has been properly serviced and is in good working order, which supports the credibility of the readings taken. Additionally, the officer's training is important because it indicates that they understand how to operate the device correctly and can interpret its results accurately. Together, this information creates a comprehensive foundation that validates the use of the speed measurement device in legal proceedings, ensuring that the evidence submitted is both sound and admissible.
