When towing a trailer, drivers must make sure that:

The trailer is equipped with a safety chain that is attached to the frame of the towing vehicle.
The trailer has a safety chain which is securely attached to the vehicle’s bumper.
About 50% to 70% of the trailer weight is on the vehicle’s trailer hitch.
The trailer has a safety chain which is connected to a part of the trailer hitch.
Explanation

Safety chains act as a backup connection between the trailer and towing vehicle in case the hitch fails. In the event of a hitch failure, the safety chains keep the trailer attached to the vehicle and prevent it from separating and potentially causing an accident. The safety chains must not be attached to a part of the trailer hitch, but instead to the frame of both the trailer and the towing vehicle. This ensures that the chain will not be disconnected if the hitch fails.
