What distance must Type A, C, and D beacons be visible on a clear night?

Type A, C, and D beacons are critical for ensuring safety and visibility in work zones, particularly during nighttime conditions. The requirement for these beacons to be visible from a distance of 3,000 feet on a clear night has been established to ensure that drivers have ample time to react and navigate safely through work zones. The visibility distance is designed to facilitate adequate warning to motorists, allowing them to slow down and prepare for potential hazards ahead.

This requirement aligns with best practices in traffic management and work zone safety, emphasizing the importance of preventing accidents in areas where workers and construction activities are present. By having beacons visible from this distance, it enhances the overall effectiveness of the work zone safety measures in place, contributing to the protection of both workers and the traveling public.
