To begin training as a triple-trailer driver, federal rules say you must first have:
Correct answer: At least six months of experience driving a tractor-semitrailer or a tractor-semitrailer-trailer combination.
Answer options
- AAt least twelve months of experience driving a tractor-semitrailer or a tractor-semitrailer-trailer combination.
- BAt least six months of experience driving a straight truck or a passenger bus.
- CAt least six months of experience driving a tractor-semitrailer or a tractor-semitrailer-trailer combination. Correct
Why
The federal training rules for longer combination vehicles require at least six months of experience in a tractor-semitrailer or a tractor-semitrailer-trailer combination before a driver can start triples training. Time in a straight truck or bus does not count, and a longer period is not required.
