How to hit the steering wheel when reversing a semi-trailer?

Novices are often most afraid of things like reversing. Others can only give hints. The key is to accumulate experience and explore for yourself. In short, slow down when you are uncertain and get off the bus to see the actual situation. Don't be afraid of others watching jokes. We are all novices. There's nothing to be ashamed of. Look in the rearview mirror. Sometimes the distance you judge is different from the actual distance, so you have to slow down. Don't hit the steering wheel too hard and fall slowly.
