What does liquid surge do to the handling of a tanker?
Answer: A
It can move the truck in the direction the liquid waves move.
Liquid surge has negative effects on a tanker's handling characteristics. The waves within the tanker can cause the vehicle to move in the direction of the wave. For example, hitting the brakes too hard will initially surge the fluid forward and increased pressure from the forward surge will require additional braking distance to stop.
