I found that many friends don’t know much about some car knowledge. For example, a friend recently asked: Tutorial on the S-bend of a B2 large truck? Let me give you a brief introduction below so that you can have a better understanding of these car knowledge. Okay, enough nonsense. Let's get down to business. B2. When a truck passes through an S-turn, the steps are as follows: 1. When the truck enters the curve, try to stay as close to the right line as the first curve is a left turn.

2. Drive forward slowly. When you see that the left front corner is fast and the right line coincides with it, turn left.

3. After one turn, keep the front corner of the car coincident with the right line. At this time, look at the left rearview mirror. You can clearly see the distance between the rear body and the left side line from the rearview mirror. Keep it around 30cm by trimming direction. The corrected steering wheel amplitude is within half a turn.

4. When you reach the corner, walk straight back in the right direction. At this time, look at the small mirror in the front right corner of the car. From the mirror, you can see that the line between the body and the right side is about 30cm.

5. Use the above method to correct the direction back and forth. If there are no small mirrors in front of the car, you can look in the large rearview mirror. At the end of the curve, turn right and exit the curve.
