How to drive safely when passing through a tunnel

1. Slow down and turn on the lights before entering the tunnel. When the vehicle enters about 100 meters before the tunnel, reduce the speed, increase the distance from the vehicle in front, and turn on the lights.

2. Observe the signs. Before a car enters a tunnel, drivers should carefully observe the traffic signs at the tunnel entrance, and trucks should pay special attention to the height limit. Before entering the tunnel, the loading height of the cargo should be carefully measured.

3. Do not turn on the high beam. Turn on your lights when driving in a tunnel, but do not turn on high beams. The lighting inside and outside the tunnel is poor, causing poor vision for the driver. If you turn on the high beam, it will be more dangerous.

4. Overtaking is prohibited. The lighting in the tunnels is poor, there are usually only two or three lanes, and overtaking is not allowed.

5. Speeding is strictly prohibited. There are strict speed limits in the tunnel. Before entering the tunnel, speed limit signs are prominently posted. Some tunnels also have speed limits. Speeding is strictly prohibited to ensure driving safety.

6. Don’t honk the horn. The sound collection effect is obvious in the tunnel, and the noise produced by honking the horn is more harsh than outside the tunnel, so do not honk the horn in the tunnel.

7. Use air conditioning internal circulation. The air circulation in the tunnel is poor, and the exhaust from other vehicles will enter the car through the windows, so it is best to close the windows and turn on the internal circulation of the air conditioner to maintain air circulation in the car.

8. Keep distance between vehicles. After entering the tunnel, pay attention to the distance between the left and right cars, as well as the distance between the front and rear cars. If you find that the car behind you is too close to the car behind you in the rearview mirror, you can light the brake light to remind the car behind you to keep the distance.

9. Parking is prohibited. Due to the poor visibility and heavy traffic volume in the tunnel, you cannot park at will. Parking in tunnels can easily lead to rear-end collisions and other serious traffic accidents. If there is an emergency, you can enter the emergency parking area.

10. Accelerate evenly after exiting the tunnel. When a vehicle exits a tunnel, its eyes need to adapt to the outside light. After adapting, the vehicle must leave at a constant speed.
