What precautions should be taken when driving into a tunnel?

When driving into a tunnel, it is important to reduce speed and turn on lights before entering, strictly avoid speeding, and refrain from changing lanes. The details are as follows: Reduce speed and turn on lights before entering the tunnel: Approximately 100 meters before entering the tunnel, you should reduce your speed, increase the distance between vehicles, and turn on the headlights to enter the tunnel safely at a relatively slower speed. Strictly avoid speeding: Tunnels usually have strict speed limits, which are indicated on prominent signs before entering. Some tunnels also have speed limit reminders inside. Do not change lanes: Due to poor lighting inside tunnels, especially near the exits, and typically only having two or three lanes, changing lanes is strictly prohibited. Always drive in your designated lane and avoid overtaking.
When driving into a tunnel, I always make sure to turn on the headlights, even during the day, because the sudden dimming of light inside the tunnel makes it easy for others to miss seeing my car, and I also have trouble seeing the road clearly. In terms of speed, I slow down in advance, usually to within the speed limit, to avoid sudden braking at the entrance that could cause a rear-end collision. Inside the tunnel, I maintain a sufficient distance from the car in front, typically leaving a two-second gap, so that if someone stops suddenly, I have enough reaction time. I also pay special attention to adapting to the light when exiting the tunnel, gradually accelerating after exiting to avoid being suddenly blinded by sunlight. Since air circulation is slow inside the tunnel, I check whether the windows are closed or the air conditioning is set to ventilation mode, but opening the windows too much creates a lot of noise. Keeping these points in mind makes driving safer and reduces problems.
