What is the purpose of safety chains on a trailer?

• A. Aesthetic purpose
• B. Increase cargo capacity
• C. Provide a secondary connection if the primary coupling fails.
• D. Improve braking efficiency

Answer: (C)

Safety chains provide a secondary connection between the trailer and the tow vehicle. If the main coupling fails or comes unhitched, the chains keep the trailer attached so you can slow down and stop safely, preventing the trailer from separating and causing a crash. They help maintain some control and keep the trailer from wandering as you respond to the situation. They aren’t meant to increase cargo capacity, improve braking, or serve cosmetic purposes. Attach them to the proper anchors on the vehicle and trailer, and they’re typically crossed under the tongue so the tongue is caught if the hitch fails; allow enough slack for turning but avoid letting them drag on the road.
