How to ensure the safety of tunnel traffic?
1. Slow down and turn on the lights before entering the tunnel
When entering the tunnel during the day, the light instantly dims, and the human eye needs to adapt, so before entering the tunnel, you should reduce the speed, turn on the headlights, and drive according to the speed limit sign in front of the tunnel.
2. Pull away from a sufficiently safe car
Due to the short blindness of the line of sight when entering and leaving the tunnel, it is necessary to maintain a long distance. In general, the driving distance in the tunnel should be maintained at more than 100 meters, and the specific can be adjusted according to the prompts.
3. Do not change lanes
Due to the poor light in the tunnel, especially at the entrance and exit of the tunnel, and usually only two or three lanes, it is strictly forbidden to change lanes in the tunnel, let alone overtake.
4. Speeding is strictly prohibited
There are often strict speed limits within the tunnel. Speed limit signs are generally set in a prominent position before entering the tunnel, and some tunnels also have speed limit reminders inside the tunnel, which should be strictly observed.
5. Do not turn on the high beam
High beams can severely affect the vision of the driver of the oncoming vehicle. The poor light in the tunnel, the driver's line of sight is obstructed, coupled with the influence of high beams, the driving hazard factor is multiplied.
6. Horns are prohibited
The effect of tunneling is more obvious, and the noise generated by pressing the horn is more obvious than that outside the tunnel, causing interference to oneself and others.
7. Rational use of air conditioning internal circulation
It is not recommended to open windows inside the tunnel because of the poor air quality inside the tunnel. When driving inside the tunnel, it is best to close the windows and open the air conditioner to keep the air circulating inside the car.
8. Speed up quickly after driving out of the tunnel
As when driving into the tunnel, you should also slow down when driving out of the tunnel, but accelerate away after the eyes have adapted to the outside light, so as not to pose a danger to the rear car.

Inside the tunnel, there is a fire alarm button every 50 meters.
At the same time, there is a fire fighting equipment box, which is equipped with dry powder fire extinguishers, fire hydrants, and foam fire extinguishing devices. In the event of a fire accident in the tunnel, the owner can take it out and use it directly. In the early stage of the fire, when the scale is small, the dry powder fire extinguisher or fire hydrant can be used to extinguish the fire, especially in the oil fire, the foam fire extinguishing device can be used to extinguish the fire.
