Tunnel driving safety

Tunnel driving safety

1. Pay attention to the warning signs before entering the tunnel

There are traffic information warning signs with width and height restrictions at the entrance of the tunnel. When driving into the tunnel, Be sure to read the prompt information clearly and drive according to the regulations.

2. Pay attention to slow down and turn on the low beam headlights

Although there are lights in the tunnel, the internal ambient light is still dark. Therefore, for safety reasons, you should slow down before driving into the tunnel. Increase the vehicle speed and turn on the low beam headlights to obtain sufficient light and vision. At the same time, the illuminated light source will also attract the attention of the vehicle ahead and serve as a driving reminder.

3. Take off your sun visors before entering the tunnel

When driving against the light, many riders will wear sun visors to reduce the impact of high-intensity ambient light. But before entering the tunnel, be sure to take off your sun visors. Because sun visors may cause visual delay, causing our perception of speed to be distorted and our judgment of vehicle speed to be incorrect.

4. Keep a distance between cars and do not exceed the speed

There is also a maximum speed limit in the tunnel. Usually, due to the poor visibility of the tunnel, the maximum speed limit inside the tunnel is lower than outside the tunnel. The road has a maximum speed limit. Therefore, when driving in a tunnel, be sure to keep a distance from the vehicle in front and do not speed. Leave enough safety distance in case of emergencies.

5. Do not overtake in the tunnel

Have you ever noticed the lines drawn on the lanes in the tunnel? Generally, they are solid white lines, which means that after entering the tunnel, you cannot change lanes, including overtaking. Overtaking in tunnels is very dangerous, especially in dimly lit tunnels. Forced overtaking can easily lead to accidents. Some tunnels are narrow on both sides, making it easy for overtaking vehicles to hit the side of the road and causing accidents. Dotted lines mark road sections in the tunnel, allowing for flexible lane changes.

6. Do not park at will in the tunnel

If a vehicle breaks down, it is the habit of many car owners to pull over immediately to deal with the problem. However, due to poor lighting conditions in the tunnel, collisions can easily occur if you are not careful. Therefore, if the vehicle breaks down but can still continue driving, you can pull over for inspection after exiting the tunnel. Never park a broken down vehicle directly in the middle of the tunnel, as this is extremely dangerous! When a vehicle has an emergency failure, you should make predictions and pull over in time to deal with it.

7. Do not turn on high beams

We have mentioned the dangers of abusing high beams many times. The space inside the tunnel is cramped, and turning on high beams will harm the vehicles ahead and oncoming vehicles. The driver's observation field of view causes strong interference and affects driving safety. There are lights inside the tunnel, and turning on the low beam headlights is enough to ensure our visibility while driving in the tunnel.

8. Try not to blow the horn in the tunnel

Because the shape of the tunnel is long and narrow, the sound convergence effect is more obvious, making the sound more concentrated and prominent, so try not to blow the horn in the tunnel. Honk the horn. "Light Language" can be used in emergencies.

9. Reasonable use of air-conditioning internal circulation

The ventilation conditions in the tunnel are not good and the air is stagnant. Therefore, it is recommended that riders do not open windows in the tunnel to prevent exhaust fumes from other vehicles from entering. The interior of the car affects the air quality inside the car. When driving in a tunnel, it is advisable to close the windows and turn on the internal circulation of the air conditioner to maintain air circulation in the car.

10. Do not speed up immediately after exiting the tunnel

After exiting the tunnel, due to obvious changes in the environment, the light suddenly increases, and the instantaneous change in light will cause eye discomfort, so exiting the tunnel When driving, you should maintain the speed of the vehicle to allow your eyes to adapt and see clearly the environment and road conditions ahead, and do not speed up hastily.

11. Don’t overtake and park casually

Some drivers will immediately pull over for repairs if they encounter problems while driving. Driving on the highway, especially in tunnels, this habit should be completely changed, otherwise it can easily lead to a series of car crashes.

First of all, the tunnel is not a parking lot. If the tunnel is used as a parking lot to take shelter from rain, rest, or repair cars, traffic jams, collisions, and collisions will occur at any time. Secondly, pay attention to changes in summer temperatures. The temperature inside the tunnel in coastal areas is lower than the temperature outside the tunnel. Cool climate can make drivers feel tired and numb, which can easily lead to accidents.

If a vehicle breaks down in a tunnel, as long as the vehicle can continue to drive, it must drive out of the tunnel as much as possible; when the vehicle cannot exit the tunnel, the people on the vehicle must leave the vehicle quickly and try to move the vehicle to a dedicated At the parking point, turn on the hazard warning lights, set up a warning sign 150m behind the vehicle, and call the highway management center through the emergency phone.
