The blind spot of a car refers to the area where the line of sight is blocked by the car body and cannot be directly observed. It is very important to know the blind spot of safe driving, especially to tell children never to play at the rear of the car.

First, the blind spot of sight caused by the car itself

1, front blind area

There are several factors that cause the blind spot in front of the car, such as the height of the car body, the height of the seat, the length of the front of the car and the driver's figure. If the distance of the blind spot in front of the car is not well controlled, it is easy to rear-end collision.

Coping methods: Try to keep enough distance from the front car or obstacles, be familiar with the distance of the blind spot in front, control the good car, sit normally when driving, and don't stagger.

2. Rear blind spot

The rear blind area refers to the area extending about 30 degrees from the rear door of the vehicle, which is out of the field of view of the reflector. The popular saying is that if the front of the rear car is close to the back door of the front car, there is no car in the mirror of the front car, and it is easy to scrape and rear-end the car if you don't pay attention.

Countermeasures: Get into the habit of checking whether there are obstacles behind the vehicle before starting, and reverse slowly. If there are other people, you can ask others to help you keep enough distance from obstacles, get familiar with the distance of the rear blind area and control the vehicle.

Second, the blind spot of sight caused by the driving environment

1, there are hidden dangers under the elevated pier.

There are many elevated roads in Guangzhou, which can be said to have become one of the characteristics of Guangzhou. When you walk in the driveway next to the pier, the thick pier virtually forms a terrible blind spot.

Solution: If you have a choice, try not to take the lane closest to the pier, although that lane is often the most unobstructed. Pay special attention to the road conditions near the pier. If you need to turn left or turn around, you should also pay attention to controlling the speed, keep a high degree of vigilance at all times, and keep enough distance from the front car to prevent the front car from suddenly braking and causing rear-end collision.

2. Deck and top of slope

When the vehicle crawls on the inclined bridge deck and reaches the highest point, the driver's line of sight will leave the road at this time, resulting in a blind spot of sight. If you don't avoid oncoming vehicles, traffic accidents will often happen.

Solution: Move the vehicle as far as possible to the outside. When you leave the road, you should honk your horn to attract the attention of oncoming vehicles.

When the temperature rises in summer, cars are prone to various hidden dangers when driving at high temperature for a long time. Tire puncture is one of the most common and dangerous accidents. How to deal with a flat tire when driving?

For a flat tire, many car owners have their own set of preventive measures to decompress the tire and sprinkle water on the high-temperature tire. These methods are not only not conducive to tire explosion protection, but also may affect automobile safety.

How to pre-tie a tire

First, if you need to park for a long time, you'd better park your car in a cool place to avoid the tires being exposed to the sun. Be sure to check the air pressure when the tires are cooled, including the spare tires.

Second, always check whether the tires are damaged, such as nails and cuts. If damaged tires are found, they should be repaired or replaced in time. If the tire has been repaired many times (more than three times), it is better to replace it with a new one.

Third, check the four-wheel alignment of the vehicle regularly. If the positioning is found to be poor, it should be corrected in time, otherwise it will cause irregular tire wear.

Fourth, driving on the highway for a long time, due to the increase of tire deformation frequency, tire heat generation is large, tire temperature is also high, and air pressure is also increased. In order to weaken this phenomenon, the tire pressure can be slightly increased to 0. 1 ~ 0.2 bar higher than the standard pressure before getting on the expressway, so that the deformation range of the tire will be reduced, the heat generation of the tire will also be reduced, and it will be safer to drive at high speed.

Emergency treatment after puncture

If the tire suddenly bursts when the car is driving, the car will swing quickly at this time. Drivers should master the steering wheel, control the driving direction of the car, and quickly turn off the throttle to slow down the car. When the traction of the engine controls the speed, the rear brake can be used gently to make the car stop slowly. If you find that the steering wheel keeps swinging from side to side during driving, you'd better turn off the throttle immediately and let the vehicle slow down gradually. Do not use emergency braking, because emergency braking will increase the degree of steering wheel swing, and the car is in danger of losing control. If you can't find a suitable terrain for use at the moment, in an emergency, you can rub the side of the car body near the hillside to increase the resistance and slow down, and then send it to the repair shop for repair in time. Brake failure is a common failure after a flat tire. If the brakes fail when the car goes downhill, and the speed cannot be controlled by the vehicle's own mechanism, natural obstacles, such as rocks and trees on the roadside, should be decisively used to cause resistance to the car.
