On a sunny day, how far must Type B warning beacons be visible?

Type B warning beacons must be visible from a distance of 1,000 feet on a sunny day. This visibility distance is established to ensure that drivers can clearly see the warning signals in advance and have adequate time to react to conditions created by work zones. Such visibility standards are critical for maintaining safety on roadways, allowing drivers to assess and respond to potential hazards. The requirement for a visibility distance of 1,000 feet allows for adequate warning about work zone conditions, thereby enhancing safety for both workers and drivers.
