Which of the following is a key difference between tie down systems and safety chains?

The key difference lies in the primary purpose and function of safety chains compared to tie down systems. Safety chains are designed specifically to serve as a backup safety feature, ensuring that if a primary connection, like a hitch or coupling, fails during transport, the trailer or load remains connected to the towing vehicle. This provides an additional layer of safety to prevent accidents or disconnects while on the road.

On the other hand, tie down systems are used to secure loads to prevent them from shifting or falling off during transport. While both tie down systems and safety chains play important roles in vehicle and load safety, the unique function of safety chains as a secondary safety measure is what distinguishes them from tie down systems. Understanding this difference is crucial, especially when it comes to ensuring compliance with safety regulations and enhancing overall safety on the road.
