1. When reversing the semi-trailer, try to avoid reversing alone. It is best to find a person to get off the car and command, and keep an eye on the trend of reversing, so as to make it easier to reverse. If there is only one person, you should pay attention to observe the surrounding environment to ensure that there are no obstacles around and people to back up the car nearby to prevent accidents.
2. Slow down when reversing, don't be in a hurry.
3. Calm your mind, keep a calm and calm mind, don't kill the steering wheel all at once, you should turn the steering wheel slowly.
