When it comes to stopping trucks, which statement is accurate?
Correct answer: A bobtail tractor can be slower to stop than a fully loaded tractor-trailer.
Answer options
- AWith a heavy vehicle, put off braking until it is your last option.
- BA bobtail tractor can be slower to stop than a fully loaded tractor-trailer. Correct
- CA heavy vehicle needs less braking power to stop than a light vehicle does.
Why
Without a trailer, a tractor has little weight on its drive wheels, and its stiff springs and strong brakes lock the wheels easily, so smooth stops are hard and tests show it can need more distance than a fully loaded tractor-semitrailer. Heavier vehicles actually need more braking power, and braking early is safer than waiting.
