What should the motor vehicle pay attention to before entering the expressway tunnel?

Turn on the low beam and drive. There will be a signboard about 150m-200m in front of each tunnel entrance, indicating the tunnel length and speed limit. (The required speed of each tunnel is not exactly the same) Please drive as required! Generally speaking, the direct speed limit around Jinan is 80-90, and there are 80 and 90 different speed limits.

Matters needing attention in driving in expressway tunnel

The steering wheel often floats when entering and leaving the tunnel. This is because the tunnel exit is the place where the crosswind is fiercest, and these two places are the places where the airflow is the most chaotic. A severe crosswind will overturn a high-speed vehicle. The simplest and most effective solution is to slow down and hold the steering wheel.

After leaving the tunnel, because the light suddenly brightened, people's pupils contracted sharply at this time, and the road conditions could not be seen clearly in an instant. So it is necessary to slow down!
