How does checking the condition of the trailer's safety chains contribute to safety?

Checking the condition of the trailer's safety chains is crucial for maintaining safety on the road. Safety chains serve as a backup connection between the vehicle and the trailer. In the event of a coupler failure — where the primary hitch connection breaks — the safety chains prevent the trailer from completely detaching and becoming a hazard to other road users. They are designed to hold the trailer securely and guide it back to the tow vehicle, helping to avoid accidents and potential damage. Proper inspection ensures that the chains are intact, free of wear, and capable of handling the weight of the trailer, which is essential for safe towing practices.
