What should you observe about the coupling when visually checking a converter dolly?

When visually checking a converter dolly, it is crucial to ensure that it is securely connected without any visible space. This means that the coupling should fit tightly together, indicating that it is properly attached and will be able to handle the stresses of driving without separating or becoming loose. A secure connection is vital for safety, as any separation can lead to a dangerous situation while the vehicle is on the road.

The presence of a tight fit ensures that the converter dolly and the trailers it connects are stable, reducing the risk of sway or detachment during travel. Proper inspection of this connection is essential for preventing accidents and maintaining control over the loaded trailers behind the towing vehicle.
