CDL · Tank vehicles
One of the two main reasons that a liquid tanker must be driven with special care is:
Correct answer: The movement of the liquid within the tank.
Answer options
- AThe low center of gravity of the load
- BThe extreme weight of the liquid cargo
- CThe movement of the liquid within the tank Correct
Why
Tankers call for extra care because their load rides high and because the liquid can slosh inside the tank, and that movement can shove the vehicle and help tip it over in a turn or sudden maneuver. A tanker's center of gravity is high, not low, and the sheer weight of the cargo is not one of the two reasons.
