What are the precautions for driving in tunnels?

Turn on the headlights when entering a tunnel. This allows for better visibility of the traffic ahead. Below are relevant instructions for driving into tunnels: Observe warning signs before entering the tunnel: There are traffic signs indicating width and height restrictions in front of tunnels. Make sure to clearly see the warning signs and drive accordingly. Reduce speed and turn on lights before entering the tunnel: If driving during the day, the light will instantly dim upon entering the tunnel, and human eyes often take some time to adjust. Therefore, before entering the tunnel, reduce speed, increase following distance, and turn on the headlights to safely enter the tunnel at a relatively slower speed. Generally, tunnels have clear speed limit signs, so you can drive according to the speed limit prompts before the tunnel.
I pay close attention to safety rules when driving through tunnels. Turn on the low beams before entering the tunnel, avoid using high beams as they may dazzle oncoming vehicles. Slow down appropriately, as the speed limit is usually lower than outside, typically 60 or 80 km/h depending on the signs. Maintain a longer following distance, allowing at least two seconds of reaction time in case the car ahead brakes suddenly. The air quality inside tunnels is poor, so switch the AC to recirculation mode to prevent exhaust fumes from entering. Never attempt to overtake, as the confined space increases the risk of side collisions. Stay focused on the road and avoid distractions like using mobile phones; keep navigation volume minimal for guidance only. Upon exiting the tunnel, allow a few seconds for your eyes to adjust to the light before accelerating. Regularly check your vehicle's lights and tire pressure to ensure they're functioning properly. Remembering these details makes tunnel journeys much safer.
