CDL · Doubles and triples
Compared with driving a smaller vehicle, what does pulling doubles or triples require of you?
Correct answer: More following distance and extra care in bad weather and in the mountains.
Answer options
- AThe same following distance as a car and no special care in bad weather.
- BLess following distance and higher speeds on mountain grades to keep momentum.
- CMore following distance and extra care in bad weather and in the mountains. Correct
Why
Doubles and triples are long and cannot be stopped or turned quickly, so they need more room ahead than smaller vehicles. Their length and extra unpowered axles also raise the risk of skids and lost traction, so slippery roads, bad weather and mountain driving call for special caution.
