How should safety chains be configured to support the trailer's coupler?

The configuration of safety chains is critical for ensuring the trailer's coupler remains secure during transport. When safety chains are crisscrossed, they create a cradle effect beneath the trailer tongue. This design helps catch the trailer in case it becomes detached from the hitch, preventing it from completely falling onto the roadway. Additionally, this arrangement allows for better distribution of weight and tension, reducing the likelihood of the chains coming loose.

If safety chains were arranged in a straight line or parallel to the trailer, they would not provide the same level of security. These configurations would offer minimal support if the trailer detaches, increasing the risk of the trailer tipping or rolling away. A loosely twisted configuration could lead to the chains loosening further during travel, which compromises their effectiveness. Thus, crisscrossing the chains is the safest and most effective way to secure the trailer to the towing vehicle.
