Red flashing lights: what must you do?

• A. If there is a red X on your lane you must not go beyond that signal in your lane; if it is on the central reservation you must not go beyond the signal in any lane.
• B. Ignore red X if in a hurry.
• C. Red X means you should slow down but may continue.
• D. Red X indicates a toll plaza.

Answer: (A)

Red flashing lights show a lane or the carriageway ahead is closed. When a red X is shown over your lane, you must not drive beyond that signal in that lane. If the red X is positioned on the central reservation, you must not go beyond the signal in any lane. In practice, you should move to an open lane as soon as it’s safe, or slow and stop in a safe place if the closure blocks the way and you can’t change lanes. These signals are about safety and lane control, not about speed or tolls.

So, ignoring it is unsafe and illegal, slowing down but continuing is not permitted, and a red X is not a toll plaza indicator.
