Why is it important to use safety chains when towing a trailer?

Using safety chains when towing a trailer is crucial because they serve as a secondary connection between the trailer and the towing vehicle. In the event that the primary hitch fails or becomes detached, the safety chains act as a backup, helping to prevent the trailer from completely separating from the towing vehicle. This added security significantly reduces the risk of accidents, as it keeps the trailer connected and under control, minimizing the potential for damage, injury, or fatalities on the road.

The function of safety chains is primarily about safety; if they were absent or ineffective, a detachment could lead to loss of control, potentially causing dangerous situations for both the driver and other road users. This makes safety chains an essential component of safe towing practices.
