What are the skills for reversing a semi-trailer?

There are many skills for reversing a semi-trailer. Here are the details: 1. Beginners should start with straight-line reversing: Keep your hands soft and your mind calm, and slowly observe the swinging pattern of the trailer in the rearview mirror. Practice until you can control the throttle to minimize the left and right swinging range. The smaller the swing range, the more solid your basic skills are. Understanding the rhythm of steering, anticipation, and the ability to turn and correct the wheel are key insights gained from straight-line practice. 2. Side positioning, which means maintaining a straight line on a slope: Train yourself to control the trailer through the rearview mirror without losing control. 3. Reversing a semi-trailer at a 90-degree angle is achieved by combining large side positioning with straight-line reversing: The method is to reverse straight first and then turn. Different lengths of trailers react differently to steering, and different steering mechanisms also affect the trailer's response. However, the principle is universal: a trailer will always move in a straight line at any time and place. To make a straight trailer follow a curved path, it requires the tractor's drive wheels to push and maintain the process.
When I back up a semi-trailer, the first thing I do is slow down—any sudden movements can make things a mess. I've learned from experience that semi-trailers are different from regular vehicles; the cab and trailer are separate, and the trailer tends to swing uncontrollably when reversing. So, I always check the mirrors first to ensure clear visibility and get used to those blind spots. Before starting, choosing the right spot is crucial—it's best to practice in an open area and avoid busy times. Steering is key: if the trailer drifts to the left, I quickly turn the steering wheel to the right to straighten it, and vice versa. At first, I often made mistakes, like oversteering, which caused jackknifing, but I got better with practice. Keep the speed at 1-2 km/h, avoid hitting the gas, and use the brake for fine adjustments. Sometimes, I ask a friend to stand outside and guide me with hand signals for extra safety. Remember, reversing is a skill—the more you do it, the easier it gets. Potholes or obstacles on the road can also throw off the balance! In short, patience and practice are key—safety first, take it slow, and you can handle any terrain.
