The term "4-way" typically refers to a type of intersection where four roads meet. In traffic management, 4-way intersections can be controlled by stop signs or traffic signals, allowing vehicles to navigate safely. These intersections are common in urban areas and require drivers to be aware of other vehicles and pedestrians. In a different context, "4-way" can also describe a type of electrical switch that allows control of a single light fixture from multiple locations. This is often used in larger homes where multiple entry points to a room exist. Such switches enhance convenience and safety in lighting design.
