What are the safety precautions for driving in tunnels?

Safety precautions for driving in tunnels are as follows: Reduce speed and turn on low beam before entering the tunnel: Approximately 100 meters before entering the tunnel, you should reduce your speed, increase the following distance, and turn on your headlights. Maintain a relatively slow speed to enter the tunnel safely, generally not exceeding 60 km/h. The specific speed should be adjusted according to the speed limit signs before the tunnel. Driving with low beams in the tunnel not only allows you to see the road conditions ahead clearly but also makes your vehicle more visible to others. This is crucial because the majority of tunnel accidents are caused by drivers misjudging the positions of other vehicles. Maintain a safe following distance: Keeping a safe distance ensures you have enough space to maneuver and enhances safety. Generally, the following distance in a tunnel should be at least 100 meters. For longer tunnels, adjust the distance according to the posted guidelines. If a breakdown occurs in the tunnel, try to leave the tunnel before handling it: If your vehicle breaks down in the tunnel, try to exit the tunnel first. The poor lighting inside makes it difficult to take measures, and the tunnel poses more hazards. Leaving the tunnel is the best way to protect yourself. Do not accelerate hastily when exiting the tunnel: When exiting the tunnel, drivers may experience the "white hole effect," which can temporarily impair vision. Be extra cautious and avoid speeding up abruptly to prevent rear-ending slower vehicles ahead. Avoid using high beams: Using high beams for extended periods at night can affect oncoming and preceding vehicles, as high beams can cause temporary blindness. Inside the tunnel, the contrast between light and dark already strains the driver's vision. Adding high beams increases the risk of accidents, so avoid using them.
Driving in tunnels really requires extra caution. I remember once on a long trip, I forgot to turn on my lights before entering a tunnel and it was pitch black inside—almost caused an accident. Since then, I switch on my low beams 5 seconds before entering to let my eyes adjust to the darkness. Maintaining proper following distance is crucial in tunnels; I usually keep at least 50 meters to avoid rear-ending someone if they brake suddenly. Absolutely no lane changes—it's too dangerous, especially in tunnels with many curves and poor visibility. Air quality matters too; I use recirculation mode to avoid inhaling exhaust fumes. When exiting, slow down gradually so your vision can readjust to the bright light. Always note the location of emergency phones in case you need immediate help. Bottom line: steady and cautious driving is the safest approach.
