Safety chains should be used when towing which of the following?

Safety chains are an essential aspect of towing, as they provide a crucial backup connection between the towing vehicle and the trailer or load. In the event that the primary connection (such as a hitch) fails, safety chains help prevent the trailer from completely detaching and can keep it in close proximity to the towing vehicle. This significantly enhances safety on the road.

When considering safety practices in towing, it is important to note that they apply universally to all types of tows, whether heavy, long, emergency, or any other scenario. Heavy loads increase the risk of failure due to the weight and strain involved, long tows can introduce unexpected conditions that may lead to connection failures, and emergency tows carry the added pressure and unpredictability of urgent situations. Thus, using safety chains is recommended for all tows to ensure maximum safety, stability, and control, making the practice universally applicable for all towing scenarios.
