When is it permissible to use a slip road at traffic lights?

Using a slip road at traffic lights is permissible on any light, which allows for more flexible driving maneuvers. A slip road is designed to facilitate the smooth transition of vehicles from one road to another, often enabling drivers to bypass certain traffic conditions or intersections.

This regulation reflects the importance of maintaining traffic flow and providing drivers with options to navigate efficiently. For instance, if the main traffic light is red and a vehicle can use a slip road to safely turn onto a different route that has a green light, it can help reduce congestion and improve overall traffic dynamics.

The various options highlight restrictions that might not account for the intended purpose of slip roads, which is to enhance vehicle movement under different traffic light conditions while adhering to safety protocols. Hence, using a slip road at any light remains a valid and encouraged practice when done safely.
