Division 3.4.6 Towing devices
United Kingdom
All machinery used to tow or to be towed must be fitted with towing or coupling devices designed, constructed and arranged in such a way as to ensure easy and secure connection and disconnection and to prevent accidental disconnection during use.
Insofar as the tow bar load so requires, such machinery must be equipped with a support with a bearing surface suited to the load and the ground.
