What should the driver do when the vehicle is about to exit the tunnel?

When exiting the tunnel, the driver should pay attention to height and speed limit signs; choose the lane indicated by the green arrow signal light; and turn on the headlights in advance. The following are precautions for driving through tunnels: 1. Slow down and turn on lights before entering the tunnel: Reduce speed about 100 meters before entering the tunnel, increase the following distance, and turn on the vehicle lights while driving slowly into the tunnel. Generally, the speed should not exceed 60 km/h, depending on the speed limit signs before the tunnel. 2. Do not use high beams: While driving in the tunnel, turn on the vehicle lights but avoid using high beams. The significant difference in light intensity inside and outside the tunnel already affects the driver's vision, and high beams can further increase the risk. 3. Maintain a safe following distance: Generally, the following distance in the tunnel should be kept at least 100 meters. If the tunnel is relatively long, maintain a safe distance as indicated. 4. Do not change lanes: Due to poor lighting and typically only two or three lanes, lane changes are strictly prohibited in tunnels. Always drive in your designated lane and avoid overtaking. 5. No speeding in the tunnel: Tunnels have strict speed limits, which are clearly marked before entering. Some tunnels also have speed limit reminders inside. Strictly adhere to the speed limits to ensure driving safety. 6. Avoid honking in the tunnel: The tunnel's acoustics amplify noise, making honking much louder and more irritating than outside. Drive patiently in the tunnel and avoid unnecessary honking unless in an emergency, to avoid disturbing yourself and others.
I always remind myself to slow down before exiting a tunnel because the sudden bright light at the exit can dazzle my eyes for a few seconds, which is called the white hole effect and is quite dangerous. Therefore, I usually reduce my speed below the limit in advance, maintaining a safe distance from the car in front to guard against sudden stops or road potholes. It's also important to avoid accelerating sharply when exiting, as there might be traffic or obstacles outside, increasing the risk of collision. Additionally, turning on the lights is crucial to ensure the taillights are on, making you visible to others. In case of rain or fog, extra attention is needed to observe environmental changes after exiting the tunnel. In short, safe driving is no small matter; taking it slow ensures a safe journey home.
