Safety Chains
Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch.
Always leave just enough slack so the rig can turn. Never allow safety chains to drag on the ground.
