What does a "safety chain" do in towing operations?

A safety chain in towing operations serves a crucial function by preventing the detachment between the tow vehicle and the trailer. It is a critical component designed to ensure that if the primary hitch fails or becomes disconnected, the trailer remains securely attached to the towing vehicle. This not only enhances safety for the driver and other road users but also helps to avoid property damage or accidents.

The installation of safety chains should follow specific guidelines, including crossing the chains under the trailer tongue to provide additional support, thereby catching the trailer if it starts to detach. They must also be of appropriate strength to handle the weight of the trailer, ensuring they effectively fulfill their purpose. By securely linking the two, safety chains play an essential role in safe towing practices.
