From how far away should a flagger be visible to drivers?

A flagger should be visible to drivers from a distance of 1,000 feet to ensure that motorists have ample time to respond to the presence of work zone conditions. This visibility distance is crucial for safety as it allows drivers to slow down and prepare for any potential hazards. The requirement for a 1,000 feet visibility ensures that flaggers can effectively communicate traffic control information to drivers well before they reach the work zone, significantly reducing the risk of accidents. This distance is established based on research and standards within work zone safety protocols, aiming to protect both the workers in the zone and the traveling public.
