What must a trailer be equipped with to avoid rejection during inspection?

A trailer must be equipped with an emergency chain or steel cable to avoid rejection during inspection because these safety features are critical for securing the trailer to the towing vehicle. In the event that the trailer becomes disconnected while in motion, the emergency chain or steel cable acts as a fail-safe to keep the trailer from separating completely, which can prevent accidents and injuries. This is a requirement in many states, including Virginia, to ensure safe towing practices on the road. Properly installed and functioning emergency attachments play a vital role in enhancing the overall safety of towing operations.
