Your car is immobilised by a breakdown inside a tunnel. Of these actions, which should you take immediately to warn vehicles approaching from behind?

Correct answer

Switch on the hazard warning lights

Switch on the hazard lights and keep the position lights on. Switch off the engine once immobilised. If it can continue safely, leave the tunnel or reach an emergency area; otherwise use that area if possible or stop close to the right edge. Request help through an SOS post if available and follow instructions. If leaving the vehicle, use the area excluded from traffic, where available, to reach a refuge or exit. Do not confuse this breakdown with stopping in congestion.
