Broken couplings and pintle hooks are a result of a jackknifed trailer.
Trailer jackknifing usually occurs when reversing and unfortunately the driver is blissfully unaware the trailer is even approaching jack-knife angles.

If you are unlucky like me, I was never taught how to reverse a trailer or caravan. In 1970, my driving instructor asked me to reverse park the mini into a roadside car park which I did perfectly.
If he asked me to do the same with a trailer coupled to the vehicle, this 18-year-old would have failed his driving test.
These days, caravan driver training is available and of course, I would recommend folks take advantage of the instructor’s words of wisdom, after all, he is skilled in the art of caravanning.
There is much to learn about the do’s and don’t. Like, how do you tell if a hot wheel is pending bearing failure or hot brake shoes?
Ask your caravan trainer, he will know the answer.
Finally, there are lots of good tips on how to reverse a caravan without jack-knife from the trainers.
