You are inspecting a converter dolly. What must be true of its pintle hook connection?
Correct answer: The hook is latched, and the dolly's pintle eye sits fully in it.
Answer options
- AThe hook is left unlatched so the dolly can swing freely in turns
- BThe hook has been repainted at some point within the past year
- CThe hook is latched, and the dolly's pintle eye sits fully in it Correct
Why
The pintle hook is what connects the dolly to the trailer ahead, so the eye must be fully seated and the latch closed; otherwise the dolly could come loose.
