Liquid tankers require extra care for two main reasons. What are they?
Correct answer: A high center of gravity and surge from the moving liquid.
Answer options
- AA low center of gravity and surge from the moving liquid
- BA high center of gravity and surge from the moving liquid Correct
- CA high center of gravity and cargo that never shifts
Why
A tanker is top-heavy because much of its load rides high above the road, which makes rollovers more likely. In a partly filled tank the liquid also surges, and that moving weight can push the vehicle forward, backward or to the side.
