Question: 1 / 400

What do red motorway studs indicate?

The edge of the road

Red motorway studs serve a specific function on the roadway. They are designed to indicate the edge of the road, helping drivers maintain awareness of their position, especially in low visibility conditions or at night. By aligning the red studs with the edge of the carriageway, they provide a clear visual cue for drivers to stay safely within their lane and avoid drifting off the road.

Understanding the function of the red studs is crucial for safe driving, particularly on motorways where higher speeds are involved. Other types of studs serve different purposes; for example, different colored studs indicate lane usage or hazards, but red is specifically designated for the edge. This clear coding system helps drivers navigate safely and responsibly, particularly in challenging conditions.
