You’re on a motorway and there are red flashing lights above every lane. What must you do?

Explanation: Red flashing lights above all lanes mean you must stop and wait. You'll also see a red cross lit up. Don't change lanes, don't continue and don't pull onto the hard shoulder (unless in an emergency).
