Is overtaking or lane changing allowed in tunnels?

Tunnels do not allow overtaking or lane changing. Below are the precautions for driving in tunnels: Do not use high beams: Most tunnels nowadays are equipped with lighting facilities. Although the lighting may not be very bright, using low beams is sufficient for safe driving. Never use high beams because tunnels are inherently narrow, and encountering oncoming traffic can be stressful. High beams can instantly blind drivers of oncoming vehicles in such confined spaces. If an accident occurs in this small space, it could potentially lead to a complete traffic breakdown in the tunnel. Pay attention to light changes: When entering a tunnel, the surrounding space becomes darker, which typically causes the pupils to contract to adapt to the dark tunnel environment. After driving in the tunnel for an extended period, when approaching the exit, you may notice a bright white light at the exit, making it difficult to see anything. This requires a brief moment of adaptation. During this time, remain calm and continue driving normally. As long as you stay composed, accidents are unlikely to occur.

I've been driving long-distance for twenty years, and overtaking or changing lanes in tunnels is purely playing with your life. Once in the Qinling Tunnel, I saw a slow-moving car ahead and thought about passing it, but almost ended up rear-ending it because the tunnel was dimly lit, narrow, and visibility was severely limited. Accidents caused by overtaking can block rescue efforts, easily leading to massive congestion and injuries. I learned my lesson—now I slow down before entering any tunnel, maintain a safe following distance, and never force an overtake; unless there's an emergency sign, like roadwork ahead, I cautiously change lanes. Now I advise young drivers to wait patiently inside tunnels and deal with slow vehicles only after exiting. Safe driving isn’t a joke—waiting a few extra minutes can save lives.

In terms of traffic management, overtaking or changing lanes in tunnels is strictly prohibited, as clearly stated in regulations. For example, in urban expressway tunnels, generally only the emergency lane is allowed for use; otherwise, you may be caught by cameras and fined 200 yuan with 3 demerit points. The reason is simple: tunnels are enclosed spaces with poor air quality, and sudden speed changes can easily lead to loss of control. I recommend familiarizing yourself with road signs before entering a tunnel and choosing your lane in advance. If you must handle something, find a safe exit to pull over. Compliant driving isn't just about talking the talk; it's about forming habits to reduce risks.

When I first got my driver's license, I was quite nervous about driving through tunnels. My instructor repeatedly emphasized not to overtake or change lanes, just maintain steady driving. Once in a short tunnel, I nervously changed lanes and almost scraped the wall, but luckily nothing happened. Later I understood that visibility is poor in tunnels, making overtaking too risky, so it's best to just stay straight. Now I always follow the rules when driving, keeping my eyes on the road markings in tunnels and avoiding distractions. It's best for beginners to practice several times to adapt to tunnel environments - after all, safety is much more important than rushing.

When traveling with the family, I am most cautious in tunnel sections. Overtaking or changing lanes is strictly prohibited, as it can frighten or cause motion sickness for the children in the back. I make it a habit to check the headlights before entering the tunnel, drive slower to maintain a safe distance from vehicles ahead and behind, and if there's a slow-moving vehicle in front, I patiently follow or wait until exiting the tunnel to overtake. When planning the route, I avoid peak tunnel hours, such as leaving early or returning late to bypass congestion. This way, the whole family feels at ease, and the journey is more comfortable.

As a driving enthusiast, I've analyzed tunnel characteristics: narrow space, turbulent airflow, where overtaking or lane changing can easily lead to loss of control. Technically, tunnels are designed with yellow lines for separation, and changing lanes increases blind spots; cars have lower loads in tunnels, but don't risk overtaking. It's recommended to use lane assist systems and maintain a steady speed. If you must change lanes, do so lightly only in emergency exit areas for safer and more reliable maneuvering.
