Driving Safely第 57 / 60 题
Why must tank vehicle drivers be especially cautious of empty or partially empty tanks?
a.Empty tanks cannot be steered
b.Empty tanks are always overweight
c.Partially filled tanks allow strong surge that can affect control
d.Empty tanks have no center of gravity
解析
A partially filled tank lets the liquid move freely and create strong surge during starts, stops, and turns. This surge can push or pull the vehicle unexpectedly and increase rollover risk. Drivers must anticipate the surge and handle a partial load with extra care.
