How should a tanker driver handle wet roads?

a.Drive at normal highway speed
b.Reduce speed significantly and increase following distance
c.Use cruise control to maintain steady speed
d.Drive in the left lane for better visibility

Explanation

On wet roads, tanker drivers should reduce speed significantly and increase following distance. Wet roads reduce traction, and combined with the effects of liquid surge and a high center of gravity, tankers are even more susceptible to skidding and rollovers in wet conditions.
