Green/yellow road studs mark temporary adjustments to lane layouts. What is their purpose?

• A. mark the left edge of the road
• B. mark the central reservation
• C. mark the edge of a main carriageway at lay-bys and slip roads
• D. mark the temporary adjustments to lane layouts

Answer: (D)

Green and yellow road studs are used to show temporary lane arrangements, such as when roadworks or diversions are in place. They signal that the normal lane pattern is altered and guide drivers through the changed lanes, helping to keep traffic moving safely around the works. Because the color indicates temporary guidance, you should follow the temporary lane boundaries and any signs or cones in the area, rather than assuming the usual lane layout.
