How should a trailors safety chains be attached to the towing veical?

Safety chains should be attached to the towing vehicle using the designated attachment points, typically located on the hitch or frame. The chains should cross under the trailer tongue to create a cradle effect, which helps prevent the trailer from dropping to the ground if it becomes unhitched. Ensure the chains have enough slack for turning but are not so loose that they drag on the ground. Always check that the connections are secure and inspect the chains for any signs of wear or damage before towing.
