During converter dolly positioning, the rear trailer kingpin should be about how far from the jaw opening?

• A. About a foot from the jaw opening.
• B. Flush with the jaw opening.
• C. Two feet from the jaw opening.
• D. Four inches.

Answer: (A)

The key idea is to have proper clearance between the rear trailer’s kingpin and the dolly’s jaw so the coupling can engage smoothly. About a foot from the jaw opening gives enough room for the jaw to close around the kingpin as you back under, while still allowing the kingpin to seat correctly in the jaw. If it’s too close or flush, the jaw can hit or clamp prematurely and cause binding or damage; if it’s too far, the kingpin won’t engage properly and the connection won’t be secure. So, about a foot is the best distance.
