Which area is responsible for alerting motorists about the situation ahead?

The Advance Warning Area is crucial for alerting motorists about potential hazards or changes in road conditions ahead, especially in situations involving emergency response or traffic incidents. This area is typically positioned before the Transition Area, and its primary purpose is to provide early notifications to drivers, allowing them to prepare for the upcoming changes in traffic flow or to navigate safely around an event. This can include using signage, cones, or other signals to ensure that motorists are aware of what lies ahead, thus enhancing safety for both responders and the public.

The Advance Warning Area plays a key role in reducing the likelihood of accidents and ensuring that traffic can flow smoothly. It is designed to give drivers adequate time to react, thereby minimizing confusion and potential risks that could arise from sudden changes in road conditions.
