Driving a motor vehicle inside a tunnel does not allow for temporary parking. Here is relevant information: Architectural structure: The structure of a tunnel consists of two parts: the main building and auxiliary equipment. The main building is composed of the tunnel body and tunnel portal, while the auxiliary equipment includes refuge niches, firefighting facilities, emergency communication systems, and drainage facilities. Longer tunnels also have specialized ventilation and lighting equipment. Tunnel: A tunnel is an engineering structure buried within the ground, representing a form of human utilization of underground space. Tunnels can be classified into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

Speaking of temporarily stopping in a tunnel, I encountered a special situation last time when driving with a friend. There was suddenly a strange noise from the rear of the car, and my friend wanted to stop to check. I immediately stopped him. Stopping in a tunnel is too dangerous—the lanes are so narrow that if the car behind can't avoid in time, it could lead to a serious rear-end collision. If there's a real emergency, like a vehicle malfunction, remember three steps: turn on the hazard lights immediately, try to move to the emergency stopping lane, and place a warning sign 150 meters away. Regular tunnels have emergency lanes only every few hundred meters, and underwater tunnels might not have any emergency lanes at all. Once, I saw news about someone stopping in a tunnel to change a tire, resulting in a three-car pileup behind them. If you really need to check your car's condition, it's better to drive a couple more kilometers to the exit and find a service area.

A veteran driver's reminder for beginners: Absolutely no temporary parking in tunnels. The most dangerous case I've seen two years ago was someone missing a highway exit and actually reversing in a tunnel, instantly getting rear-ended by a heavy truck. Tunnel speed limits are usually 60 to 80 km/h, and drivers entering from bright to dark areas need several seconds to adjust their vision, leaving no time to react. Especially in curved tunnels, obstructed vision makes it even more dangerous. Even if you urgently need to pee or answer a phone call, don't stop—there are usually rest areas within 3 km after exiting the tunnel. Nowadays, tunnels are densely packed with cameras, and parking for just 3 minutes triggers automatic capture—fines and demerit points aren't worth it.

From a safety regulation perspective, tunnels are enclosed spaces with multiple hazards: rapid exhaust gas accumulation, poor lighting, and noise impairing judgment. Temporary parking not only obstructs traffic but also worsens air circulation. Particularly dangerous are chemical tanker leaks in tunnels—last year's tunnel accident involved a chain-reaction collision triggered by a stalled passenger car. Standard procedure requires: moving vehicles to exit the tunnel if operable; immediately alerting authorities for complete breakdowns with all personnel evacuating to sidewalk safety shelters. Remember, never wait inside vehicles—tunnel secondary accident rates reach 37%.
