Radar Speed Sign Viewing Chart

The chart below indicates the viewing distance for various LED digit heights. For example, starting at a distance of 600 feet from the radar speed sign at a speed of 45 mph you have 9.1 seconds to view a sign with 13″ LED display. That is ideal for that speed. However, at 75 mph you have only 5.4 seconds to view the sign which is not acceptable.
