How many safety chains or cables are required for towing?

The correct choice reflects the requirement of two safety chains or cables when towing a trailer in Illinois. This number is established to enhance safety during the towing process. The purpose of having two chains or cables is to provide a backup in case one fails. When properly attached, they also help to secure the connection between the towing vehicle and the trailer, helping to prevent the trailer from swaying or separating if the primary hitch becomes disconnected.

Each chain or cable should be crossed under the trailer's tongue and securely attached to the towing vehicle. This crossing creates a cradle that can catch the trailer if it becomes unhitched, reducing the risk of a complete disconnect and potential accidents. The practice of using two chains or cables is a standard safety measure not just in Illinois, but across many jurisdictions, as it significantly increases the reliability of the towing connection.
