What must you do if a traffic controller at a road works zone displays a stop sign?

When a traffic controller at a road works zone displays a stop sign, you are required to stop your vehicle and follow their directions. This is crucial for ensuring safety in the vicinity of road works, where there may be workers, equipment, or hazardous conditions. By stopping, you allow the traffic controller to manage the flow of vehicles and pedestrians safely through the area, minimizing the risk of accidents or injuries.

In the context of road works, adherence to the instructions given by traffic controllers is essential, as they are present to manage specific situations that may not just affect traffic but also the safety of workers on site. Following their directions helps maintain order and safety in a potentially dangerous environment.
