What is the speed limit in highway tunnels?
3 Answers
Highway tunnels have speed limits of 60--80 km/h. Below is relevant information about highway tunnels:1. Highway tunnel regulations: Lane changing is prohibited in highway tunnels. Changing lanes in highway tunnels violates traffic regulations where motor vehicle drivers disobey prohibitive markings, constituting a traffic violation.2. Penalties: A fine of 150 RMB and 3 demerit points will be imposed. However, exceptions include situations where lane changing is necessary due to accidents ahead, on-site police direction, or yielding to special rescue vehicles - these won't be considered violations. Even if penalized, such cases can be revoked through administrative reconsideration.
The speed limit in highway tunnels is usually between 80 and 100 kilometers per hour, depending on the local road signs. For example, during my many long-distance drives, I've noticed that large tunnels generally have an 80 km/h limit, while shorter ones may allow 100 km/h. This is because tunnels are enclosed spaces with poor air circulation, making accidents prone to smoke accumulation or chain collisions. As a safe driving practice, I always reduce my speed by about 10% before entering a tunnel and check if my vehicle's lights are on. In rainy or foggy conditions, it's even more important to slow down. Once, while driving through a mountain tunnel at night with poor visibility, I nearly had an issue due to speeding, so for safety, it's best to stay within the speed limit. Also, pay attention to the movement of vehicles behind you and maintain a reasonable distance. Some inexperienced drivers tend to speed up to save time, but tunnels have many unexpected situations that can easily lead to loss of control. Overall, familiarizing yourself with road signs and developing a habit of driving at lower speeds are fundamental to ensuring driving safety.
When it comes to speed limits in highway tunnels, as someone who frequently drives on highways, my experience is that most are marked at 80 km/h. Before entering a tunnel, I always glance at the speed limit sign and immediately slow down. For longer tunnels, the limits can be even stricter, sometimes as low as 70 km/h. Once, during heavy rain in a tunnel, I witnessed an accident caused by someone driving too fast to brake in time. Now, I always drive slightly below the posted limit, ensuring all my lights are on. The dim visibility in tunnels makes speeding particularly risky, but even if the sign shows 100 km/h, I cap my speed at 90 km/h to avoid accidents. In real-world driving, safety always comes first. Based on my commuting experience, urban and suburban tunnels usually have a 100 km/h limit, while mountainous sections are often 80 km/h. It's essential to adjust your speed in advance based on navigation app prompts. Developing this habit has made my drives much smoother and even improved fuel efficiency.
