What is the main reason tank vehicles roll over more easily than other trucks?
a.Their high center of gravity combined with liquid surge
b.Their extra-wide tires
c.Their low ground clearance
d.Their light overall weight
Giải thích
Tank vehicles carry weight high off the ground and the liquid inside can surge and shift. This high center of gravity plus surging cargo makes them easy to tip in curves and sudden maneuvers. Driving slowly and smoothly is the best defense against rollover.
