When you see this sign, you should slow down and be prepared to stop if there are vehicles approaching on the main road. It is crucial to check for oncoming traffic before proceeding to ensure a safe merge or turn. Make sure to always give way when necessary to avoid accidents, especially at intersections or when entering a major road.
