What is a converter dolly used for?

A converter dolly is a specialized piece of equipment used primarily in combination with a tractor unit to facilitate the towing of more than one trailer. It acts as a linkage between the tractor and a second trailer, effectively extending the towing capability of the tractor. This configuration allows for greater flexibility and efficiency when transporting goods, as it enables the transportation of multiple trailers simultaneously.

In essence, a converter dolly enables the driver to manage multiple trailers, often enhancing the load capacity and allowing for more streamlined operations in logistics and freight transport. Understanding the function of a converter dolly is crucial for those seeking the Heavy Trailer Endorsement because it directly impacts safety, maneuverability, and compliance with transportation regulations.
