What is the required distance for Class B lighting to be visible during the day?

For Class B lighting, the visibility requirement during daylight hours is set at 1000 feet. This standard ensures that the lights are bright enough to be seen clearly by drivers and other roadway users, even in daylight conditions. The purpose of this visibility requirement is to enhance safety in work zones and traffic control situations, enabling flaggers and other personnel to adequately warn oncoming traffic about potential hazards or changes in road conditions.

Meeting the 1000-foot visibility standard for Class B lighting is critical for preventing accidents and ensuring that drivers have sufficient time to react when approaching roadwork or other hazards. Properly illuminated work zones contribute significantly to the overall safety of both workers and motoring public, making adherence to these regulations essential.
