CDL · Tank vehicles
What could keep you from filling a tanker all the way to capacity?
Correct answer: A dense cargo might exceed legal weight limits, and the liquid can expand on the trip.
Answer options
- AA dense cargo might exceed legal weight limits, but the liquid never expands on the trip.
- BThe liquid can expand on the trip, but legal weight limits never apply to tank loads.
- CA dense cargo might exceed legal weight limits, and the liquid can expand on the trip. Correct
Why
Liquids grow in volume as they warm, so some empty space, called outage, must be left for that expansion. A heavy, dense liquid can also push a full tank past legal weight limits, which is why such loads are often only partly filled.
