The "Stop Here On Red Signal" R6-6 Sign is essential for managing congestion during lane closures. It instructs drivers to come to a complete stop when the mobile traffic light displays red, ensuring safe and orderly traffic flow. This sign is particularly crucial in situations where a two-lane road is temporarily reduced to a single lane due to construction or hazards, helping to prevent accidents and maintain smooth traffic movement.
