What is the best way to prevent rollover in a tanker?

a.Load the tank as full as possible at all times
b.Drive slowly, especially on curves, ramps, and turns
c.Use the highest gear possible
d.Drive close to other vehicles for drafting

Explanation

The best way to prevent rollover is to drive slowly, especially on curves, highway on-ramps and off-ramps, and turns. The high center of gravity and liquid surge in tankers make them very susceptible to rollover. Reducing speed gives you more control and reduces the force of the surge.
