How to tie the trailer rope most securely?

Correct tying method of trailer rope: First, fold the trailer rope, with the long side as the main rope and the short side as the auxiliary rope, and put the trailer rope through the trailer buckle. The second step is to take out the main rope from the loop and wrap the auxiliary rope around the main rope. Step 3: Fold the auxiliary rope in half, pass it through the loop above, and then tighten the main rope. This ensures the safety of the front and rear vehicles when towing.
