CDL · Doubles and triples
If a set of doubles includes only a single 28.5-foot pup trailer, what is that configuration called?
Correct answer: A Rocky Mountain double.
Answer options
- AA turnpike double
- BA Rocky Mountain double Correct
- CA standard (STAA) double
Why
Of these three setups, only the Rocky Mountain double mixes trailer lengths, pairing a long lead semitrailer with one 28.5-foot pup. A standard STAA double uses two short pups, and a turnpike double uses two long trailers.
