Keeping Our Roadways Safe with Speed-Measuring Devices: The Importance of Maintaining Confidence in Their Accuracy

Traffic safety is an important element of keeping communities safe, enhancing quality of life, and reducing social harm. Law enforcement has the primary responsibility for protecting a nation’s roadways, a major element of which is speed enforcement.
