What is the minimum distance from which class B lighting should be visible during the day?

The minimum distance from which class B lighting should be visible during the day is 1000 feet. This requirement is important because visibility of lighting ensures that drivers can see the traffic control devices and flaggers from a significant distance, allowing them to react safely in advance. This distance is specifically established to enhance safety for both workers and roadway users in work zones. Class B lighting, often used in construction or maintenance areas, is designed to be effective in a variety of conditions, including daylight, and must meet regulatory visibility standards to provide adequate warning and guidance to motorists. Ensuring that these lights are visible from 1000 feet contributes significantly to overall traffic safety in these zones.
