I can't see anything! Self-driving on holiday alert to the "black and white double holes" on the road

Tunnel entrance and exit sections

Why are there so many accidents?

There have been 3 recent traffic accidents

The reason is the same

Let's take a look

1 Accident one

Recently, in Xi'an, Shaanxi, when Lu drove a car out of the tunnel, his eyes were stimulated by the strong light outside the tunnel and there was a brief visual blind spot, coupled with improper operation, the vehicle lost control, and after hitting the left tunnel wall, he crashed into the heavy truck on the right side again, causing damage to the two vehicles.

2 Accident two

When the two cars drove to the entrance of the Hongyan Tunnel in the Lingshan section of the Rongwu Expressway, the light suddenly dimmed, and the driver failed to find an accident that had occurred in front of them in time, and directly rear-ended the car in front of him to cause a second accident.

3 Accident Three

Also because of the lack of adaptation to the light after entering the tunnel, a small car suddenly braked after entering a tunnel in the Xinfeng section of Jiangxi Province of the Daguang Expressway, and the rear truck was rear-ended with the car because it could not avoid it.

When you travel by car during the holidays, especially on the highway, you will inevitably pass through tunnels. If you are traveling through the tunnel during the day, due to the large difference between the light and darkness inside and outside the tunnel, the entrance of the tunnel is often dark, and the exit is a dazzling white light, much like a "black hole" and a "white hole", and it takes a few seconds for the eyes to adapt to this change of light and dark. As a result, traffic accidents are susceptible to accidents at the entrance and exit sections of tunnels.

There is no way to "hide" the "black and white double hole", but you can reduce the accident through driving skills.

What should I do if I encounter a "black and white double hole" while driving in the tunnel?

1. Turn on the low beams

Before entering the tunnel, you should slowly reduce your speed in advance, keep a safe distance from the vehicle in front of you, and turn on your low beams as prompted by the speed limit signs.

2. Adjust your line of sight

Once you enter the tunnel, don't panic during the "dark adaptation" of your eyes, adjust your gaze to the far part of the tunnel, do not pay attention to the tunnel walls on both sides, and keep the original lane driving at a constant speed.

3. Keep a distance between vehicles

Maintaining a safe distance between vehicles is the most direct and effective way to prevent rear-end collisions.

4. No lane change

The lane demarcation line in the tunnel is a single solid white line, and lane changes are not allowed.

5. Steady speed

When driving out of the tunnel, you can wait for your eyes to "adjust" to the end and regain your vision, and then accelerate when you see the speed limit sign lifted.

What should I do if I encounter an accident in a tunnel or on a highway?

The 9-word rule for traffic accident handling

Whether you encounter a traffic accident in a tunnel or on the highway, you should follow the 9-character rule to avoid secondary accidents:

1. Pull over

Turn on your hazard warning flashers, move your vehicle to the emergency lane (if you are in a tunnel, exit the tunnel first) and pull over. If the vehicle cannot be moved, place a warning triangle 150 meters behind the vehicle.

2. People evacuated

In the tunnel, personnel should be evacuated to a safe place on both sides of the tunnel wall; On the highway, personnel should evacuate to the guardrail, do not stay in the car and the driving lane, in case the rear car brakes in time, the consequences are unimaginable.

3. That is, call the police

After taking protective measures, call the police in time, and if anyone is injured, call the 120 emergency number at the same time.

When there is no mobile phone signal in the tunnel, you can use the manual alarm phone and manual alarm button in the tunnel.

How to tell the police on the highway to tell their location?

1. Know the kilometer card: On the central separation zone of the expressway, a kilometer sign is generally set up every kilometer.

Above this kilometer sign is the number of kilometers in the current location, and below is the number of the highway. The reading is: S3500 high-speed forty-six kilometers.

2. Know the 100-meter card: On the corrugated guardrail next to the emergency lane, a 100-meter card is generally set up every 100 meters.

The combination of two signs can accurately locate the current location: S3500 highway 46 kilometers 100 meters. When calling the police for help, if you can't tell the difference between up and down, just say where you are going from the highway.

The National Day holiday is coming

Visit relatives and friends, and travel by car

The highway has also ushered in a wave of peak traffic

Are you stuck in traffic?

It is estimated that during the National Day, the average daily traffic of expressways across the country will be about 61 million, which is expected to hit a new high in the same period in history. On the first day of the holiday on October 1, the traffic flow of the expressway is expected to reach its peak, with 9-12 o'clock being the peak hour for outbound traffic, and the peak time is from 10 to 11 o'clock.

Keep the rule of twelve words in mind when stuck in traffic

If you are queuing up in front of you to slow down, be sure to slow down early, signal early, leave space, look forward and backward, and leave a safe response distance for yourself and other vehicles.

When can I open the windows to ventilate in a traffic jam?

It is recommended to close the windows when you are stuck in traffic for a short period of time or waiting for a red light.

When traffic congestion, the car slows down, gears, starts, and accelerates, and a large amount of gasoline will be burned, and the distance between vehicles is smaller, and the inhalable particulate matter in the air is more than 20 times more than usual.

If you are stuck in traffic jam for a long time and stop moving, do not close the windows and turn on the air conditioner.

If the car is on fire for a long time and does not start, the windows should be opened to prevent suffocation caused by exhaust backflow; Don't sleep in a car with the doors and windows closed and the air conditioner on, and open the windows when the air conditioner is stopped to prevent carbon monoxide poisoning.
