Which area gives the first indication of a potential hazard to road users?

The Advanced Warning Area is essential because it serves as the initial point at which road users are alerted to potential hazards ahead. This area is designed to preemptively inform drivers of changes in traffic flow, road conditions, or upcoming work zones. Proper signage, such as warning signs, is typically used within this area to ensure that motorists have ample time to react to the potential danger, adjust their speed, or navigate safely around the work zone.

By establishing this area before the Activity Area, where the actual work or restriction takes place, road users are given the critical information needed to prepare for the conditions they will encounter, thereby enhancing safety for both drivers and workers. The presence of this area is a fundamental principle in traffic control and safety practices, ensuring an effective transition from normal conditions to those with potential hazards.
