You’re approaching a junction where the traffic lights aren’t working. What should you do when a police officer gives this signal?

Explanation: If a police officer or traffic warden directing traffic signals you to stop, you must obey them. They'll use the arm signals shown in The Highway Code. If they're controlling traffic where traffic lights have failed, react to their signal as though it had been given by the traffic lights.
