First, the process of accelerating and upshifting semi trailers running on the road is quite cumbersome due to many gears. Therefore, once the speed is raised, drivers rarely change their minds to slow down. Most of them use driving experience skills to avoid some obstacles, and the brakes are naturally used little, which is the basis of the formation of potential accidents. If the judgment is wrong, everything will be unexpected. Overload and overspeed is another reason why the truck semi-trailer is easy to lose control. Therefore, the kinetic energy of an ordinary overloaded semi-trailer is quite large, the role of the brake is relatively weakened, and in addition to speeding, the braking burden is far greater than my ability. Therefore, the frequent accidents such as brake failure of semi-trailer are presented in this way. There are also long-distance truck semi-trailer drivers who will inevitably become tired and physically distracted due to long time and long interval driving. What's more, they will doze off when driving, especially when the road is wide and straight, or when the road is long and broken, semi-trailer drivers are most likely to suffer from visual numbness and serious accidents.

Second, in the process of driving, if there is a truck trailer in front of you, if you want to overtake, the best way is to first drive away from the truck at an interval of about 100 meters, check the road conditions in front, and under the condition that the road conditions in front are good and the vision is good, use the overtaking turn signal, horn, stroboscopic headlights, and check the direction of the semi-trailer at the same time. If the semi-trailer does not occupy the road and has no tendency to sway left and right, then increase the accelerator to quickly overtake it. After overtaking, do not immediately merge to the traffic lane. It is better to pull back to the normal traffic lane after an interval of about 500 meters with the semi-trailer. In the whole process, the direction must be firmly held. When approaching the truck, the horn and strobe headlights must stop at the same time. Why do you want to do this? The purpose is to inform the semi-trailer driver that you will overtake. Sometimes, due to overloading, you can't see your flashing lights; There are also situations where the horn warning cannot be heard due to the noise itself, so the horn and flashing must be stopped at the same time, and it is better not to continue in the whole process. Even if the truck driver falls asleep, he can be woken up by the horn to prevent the accident. Never consciously overtake at a curve or when the road conditions are not clear.

Third, you should also pay special attention to driving at night. Semi trailers are often in poor condition due to poor housekeeping. It is common for them to have uneven lighting or smoke. Therefore, the tail lights of semi-trailer running at high speed at night are very small, and even can not be seen. In addition, the black smoke from the exhaust will seriously affect the vision. It is easy to create the illusion of fog. Therefore, it is better to drive on the overtaking lane at night. When encountering sudden thick smoke, you should immediately slow down to prevent the risk of rear end collision.

The fourth rainy day is also a period of high incidence of accidents. You must pay attention to your skills when it comes to super heavy semi trailers in heavy rain. Because the wheels of the semi trailer turn, the fog will be very heavy, and following it or its side will make your front gear glass vague. Therefore, in addition to honking and flashing lights when overtaking, the wiper should also be in a continuous working state. It is better to increase the gear by one or two under normal conditions.

In addition, you must slow down when entering or leaving the tunnel, especially when following a heavy semi-trailer. As the light outside the tunnel is intense, the moment you enter the tunnel, your eyes will have a short time of dark adaptation, and you can hardly see anything; When I leave the tunnel, I am used to being dark. When I see the sun, my eyes will be dazzled, and I will have a short time of clear response. I can't see clearly. So if some trailers are parked or repaired near the hole, or the semi-trailer is out of control due to the light and dark compliance of the trailer driver. If you cross quickly or follow too closely, you will inevitably face danger.
