Why do tanker vehicles have a high center of gravity?
a.Because the engine is mounted high
b.Because the liquid cargo is carried high above the ground in the tank
c.Because of the heavy frame rails
d.Because of the oversized tires
Explanation
Tanker vehicles have a high center of gravity because the liquid cargo is carried in a tank mounted high above the road surface. This high center of gravity makes tankers more prone to rollovers, especially on curves and during sudden maneuvers.
