What should I do if I am particularly nervous every time I enter the expressway tunnel?

I think this is because there is a certain psychological shadow on the tunnel! However, this is normal. I think all high-speed tunnels and tunnels belong to the first-class danger zone and should not be taken lightly. Why do you say that? Because the construction of high-speed tunnel is limited by natural landform, construction capacity and economic benefits, even if it is built according to national standards, it is still an unsafe factor. Because of this, there will be high-speed early warning, such as slowing down at 1 km, setting flashing warning lights in the tunnel, illegal monitoring and so on. hahaha

As we all know, the reason why tunnels are set up on the expressway is mainly because the terrain in this place is steep and the expressway cannot be bypassed, so it is necessary to set up tunnels here. Therefore, when people go to running all the way from the carefree highway, the road suddenly narrows, the visibility in the tunnel is low, the speed is slow, the vehicles are crowded together, and the unsafe factors increase. The driver's nervousness is completely understandable.
