When driving through a tunnel in heavy traffic, what should you do?

• A. Follow the instructions given by variable message signs
• B. Closely follow the tail lights of other vehicles
• C. Stay close to the vehicle in front to reduce congestion
• D. Switch off your dipped headlights to reduce dazzle

Answer: (A)

In a tunnel, traffic conditions can change quickly, so the best approach is to follow the instructions shown on variable message signs. These signs give real-time guidance from traffic authorities—speed limits, lane closures, incidents ahead, and any required actions. By obeying them, you adapt to the current situation and reduce the risk of collisions or getting stuck. Tailgating or following closely behind the car in front increases stopping distances and makes you less able to react to sudden changes, which is risky in a confined tunnel. Aiming to stay right on another vehicle doesn’t help with congestion and can lead to collisions. And switching off dipped headlights reduces your visibility and makes you harder to see, which is unsafe in a tunnel where good visibility is crucial. Keep to the signs, maintain a safe following distance, and keep your lights on as required.
