Bulk Liquids & SurgeCâu 17 / 60
Which combination of hazards makes tank vehicles especially unstable?
a.Low center of gravity plus heavy weight
b.Baffles plus large outage
c.Full tanks plus low speed
d.High center of gravity plus liquid surge
Giải thích
Tank vehicles combine a high center of gravity with the surging movement of liquid cargo. Together these make the vehicle unstable and prone to rollover, especially in curves, ramps, and quick lane changes. Drivers must slow down and steer smoothly to manage both hazards.
