Answer: B — To allow a vehicle to accept a 5th-wheel trailer

The primary function of a converter dolly is to allow a vehicle to accept a 5th-wheel trailer. This specialized piece of equipment acts as a connector, enabling the attachment of additional trailers to a tractor while providing the necessary support and stability needed to tow them. The converter dolly features a coupling mechanism that connects to the 5th-wheel hitch of the tractor, facilitating the hauling of multiple trailers, such as in doubles or triples configurations. It is designed to distribute the weight of the trailers effectively and maintain proper alignment during transit, ensuring safety and maneuverability on the road. Understanding the converter dolly's role is crucial for drivers operating vehicles with multiple trailers, as it plays a key part in maintaining safe towing practices.
