Which of the following statements about a converter dolly are true?
- (a) It has an axle, a fifth wheel and a hitch.
- (b) You can use it to tow more than one trailer.
- (c) You can use it in place of a trailer.
- Both (a) and (b) are true. ✓
Answer: D. Both (a) and (b) are true.
Both statements are true: a converter dolly includes an axle, a fifth wheel, and a hitch, and it is used when towing more than one trailer.
Why this is the answer
The handbook describes a converter dolly as including an axle, a fifth wheel, and a hitch. It also says that when a driver is towing more than one trailer, a converter dolly is sometimes used. So the statement about its parts is true, and the statement about using it to tow more than one trailer is true too. That is why the choice combining those two statements is the right one.
Why the other answers are wrong
- A. (a) It has an axle, a fifth wheel and a hitch. — This covers only the converter dolly's parts, so it leaves out the separate true point that a converter dolly is used when towing more than one trailer.
- B. (b) You can use it to tow more than one trailer. — This covers only the towing-more-than-one-trailer use, so it leaves out the true description of the converter dolly's axle, fifth wheel, and hitch.
- C. (c) You can use it in place of a trailer. — The handbook says a converter dolly is used when towing more than one trailer; it does not say it can be used instead of a trailer.
Remember it
Picture the converter dolly as the extra axle-and-fifth-wheel unit that lets one truck pull more than one trailer.
