What should you do when entering a tunnel?

Pay attention to signs carefully and reduce speed for slow driving. 1. Turn on lights in advance and maintain distance before entering the tunnel: When approaching the tunnel, there will be signs reminding you to turn on your vehicle lights, but you must use low beams instead of high beams. Also maintain a driving distance of more than 100 meters to avoid accidents. 2. No lane changing or overtaking: Due to the dim lighting and narrow visibility range inside the tunnel, changing lanes or overtaking can easily lead to accidents. 3. Set air conditioning to internal circulation mode: The air inside tunnels is highly polluted, especially in longer tunnels where vehicle exhaust accumulates and cannot be discharged. Turning on internal circulation prevents polluted tunnel air from entering the vehicle.
Slow down and turn on your lights 100 meters before entering a tunnel. Experienced drivers know tunnel entrances are accident-prone zones. I always reduce speed below 80 km/h in advance, maintain distance from the car ahead, and allow a few seconds for eyes to adjust to light changes - never slam brakes during this transition. Remember to remove sunglasses, otherwise you'll be completely blind entering the tunnel. Most crucially, make yourself visible to following vehicles - daytime running lights aren't sufficient, low beams must be activated (fog lights as needed). Never change lanes inside tunnels where emergency braking reaction time is dangerously short. Avoid honking in traffic jams - the echo is unbearable. The same principles apply when exiting: anticipate blinding light, decelerate early, and ease onto the throttle while your eyes readjust.
