What happens if the primary towing system fails?

When the primary towing system fails, safety chains act as a crucial secondary measure to prevent the towed vehicle from completely detaching from the tow vehicle. These chains are designed to secure the connection between the tow vehicle and the towed vehicle, providing an additional layer of safety. If the primary attachment points, such as a ball hitch or pin, were to malfunction or break, the safety chains would help keep the towed vehicle connected, thus reducing the risk of it becoming a hazard on the road.

In this context, while winch lines can be used for anchoring and can play a role in securing a towed load, they are not an effective fail-safe solution in the event of a primary towing system failure. Similarly, while shifting cargo may occur in cases of loss of integrity, it does not address the immediate concern of vehicle detachment. Immediate servicing of the tow vehicle may be required in some scenarios, but it doesn’t provide the immediate safety assurance that safety chains do during a towing system failure.
