Which of the following is a reason for proper flagging in construction zones?

Proper flagging in construction zones plays a vital role in minimizing injury risks, which is the central focus of effective traffic control in these potentially hazardous environments. By using flaggers to communicate with drivers, the risks associated with construction activities—such as accidents, collisions, or unexpected behaviors of both workers and motorists—are significantly reduced. Adequate flagging ensures that drivers are directed safely around construction zones, which helps protect both the workers on site and the traveling public.

The use of trained flaggers who can effectively manage traffic flow and provide clear, concise signals contributes to a safer work environment. Their training equips them with the skills to anticipate driver behavior, address miscommunication, and react quickly to developing situations to mitigate dangers.

In contrast, maximizing work zone size would not directly contribute to safety; it could actually have the opposite effect by complicating traffic patterns. Enhancing personal visibility serves a function, but it is secondary to the primary goal of reducing risks. Encouraging speeding is counterproductive to safety and contradicts the objectives of a well-managed work zone, which aims to keep traffic moving at safe speeds.
