A towing brace provides a safer means of towing a vehicle than a tow rope or strap can provide.

Because a towing brace is a solid metal bar (which usually comes in smaller segments which clip together for easier transportation) it reduces the chances of the vehicle being towed running into the back of the towing vehicle during declaration or descent.

Many towing braces come with a warning flag to warn other motorists that there is a vehicle being towed.
