Speedometers are authorized for which measurement accuracy?

• A. 1/10 of a mile
• B. 1/5 of a mile
• C. 3/10 of a mile
• D. 1 mile

Answer: (C)

The authorized measurement accuracy for speedometers is 3/10 of a mile. This level of accuracy ensures that speedometers can provide reliable readings that are sufficiently precise for law enforcement purposes, particularly when evaluating compliance with speed limits. In practice, having an accuracy within 3/10 of a mile means that the speed indicated by the speedometer can vary slightly from the actual speed of the vehicle, but it still remains within an acceptable range for enforcement. This standard helps to maintain fairness in citation issuance while allowing officers to effectively monitor and enforce speed regulations. The choice of a smaller unit such as 3/10 of a mile is appropriate, as it provides a practical balance between measurement precision and the realities of vehicle speed monitoring. Other options suggest differing levels of accuracy that may not align with accepted standards for speed enforcement.
