What are the precautions for driving in tunnels?

[McManuel]

When driving through a tunnel, it is necessary to observe traffic signs and information boards, and keep to the right side of the road. The following are the key points for driving in tunnels: 1. Turn on the headlights in advance before entering the tunnel to help the driver observe the traffic conditions inside. Note that overtaking is prohibited in tunnels. 2. The light inside the tunnel is significantly weaker than outside. Failing to turn on the headlights in advance may make it difficult for the driver to adapt to the light, potentially leading to loss of control of the vehicle and creating safety hazards. Additional information: Traffic tunnels are usually transportation facilities designed for vehicles such as cars and trains. Generally, the structure of a tunnel consists of two parts: the main structure and auxiliary facilities. The main structure includes the tunnel entrance and the tunnel body, while auxiliary facilities include firefighting equipment, waterproofing, and drainage systems, etc.

I've been driving long-haul trucks for over a decade, and tunnels are the worst for sudden vision changes. You need to turn on your low beams 100 meters before entering – don't slack off, many accidents happen due to insufficient lighting. Maintaining distance is crucial; I always leave half a car length more than usual since braking distances increase in tunnels. Watch those speed limit signs – they're almost always capped at 80 km/h, and speed cameras at tunnel entrances are everywhere. Traffic jams in tunnels are nightmares – remember, no lane changes, just follow the car ahead. Once I saw a truck ahead blow a tire; that driver wisely turned on hazards and eased to the shoulder – textbook response. When exiting, that sudden sunlight is brutal – flip down your visor in advance.

Last week, I just came back from a highway trip and realized that adjusting vision is the most crucial aspect when driving in tunnels. I specifically consulted a traffic police friend, who said 60% of tunnel accidents occur at the entrance because the eyes can't adapt to the sudden light changes. He advised removing sunglasses in advance and turning on headlights even during daytime tunnel entry—headlights not only help you see the road but also make your car visible to others. I also noticed many cars have half-broken taillights, making them particularly dangerous in tunnels. If your car breaks down inside a tunnel, don't attempt repairs yourself; quickly move to the emergency parking area, turn on hazard lights, and seek safety while calling for help. When exiting tunnels, beware of crosswinds, especially on mountainous highways—on windy days, I always grip the steering wheel firmly with both hands.

As a road trip enthusiast, I've driven through many mountain tunnels. My experience is the three must-dos when entering a tunnel: turn on lights, turn off music, and reduce speed. The loud noise in tunnels can mask abnormal sounds. Once I heard an unusual engine noise and immediately slowed down, only to see smoke coming out right after exiting the tunnel. Paying attention to road markings is crucial – long tunnels often have escape route signs in the middle. Never park randomly in emergency stopping bays; they're life-saving passages. Last time in a 10-kilometer-long tunnel, I saw a novice changing tires on the driving lane, which gave me a cold sweat. The most dangerous moment is right after exiting the tunnel – the sudden bright light can whiten your vision for several seconds, so I always slow down in advance and prepare to brake.

I commute through three tunnels every day and have summarized some tips. First, keep your windshield clean—dirty glass severely impairs visibility due to the heavy moisture inside tunnels. Maintaining a steady speed is crucial, minimizing unnecessary lane changes, especially when driving close to large trucks. Set your air conditioning to recirculate mode to avoid inhaling exhaust fumes. Always check the weather in advance, as tunnel entrances often accumulate water during rain, increasing the risk of skidding. Once during a heavy storm, I failed to slow down before entering a tunnel, and my car hydroplaned over the water surface—fortunately, I gripped the steering wheel tightly. Remember to adjust your rearview mirror angle when exiting tunnels, as blinding sunlight can enlarge blind spots.

When I first started driving, I was particularly afraid of tunnels, but now I'm used to it and it's not so bad. The most strenuous part for the eyes is during the light transition, so I learned to blink a few times before entering the tunnel to help with adaptation. Maintaining a strict following distance is crucial, and the three-second rule is the most reliable: start counting when the car in front passes a reference point, and only reach that point three seconds later. Don’t grip the steering wheel too tightly—the visual pressure from the tunnel walls can easily make you unconsciously drift. Pay attention to the overhead indicators; a red cross means the lane is closed. Last week, when the tunnel was congested, I waited until the indicator turned green before daring to move into the right lane. Don’t rush to step on the accelerator when exiting the tunnel—there are often crosswinds and speed cameras.
