When driving a tanker what should you do?

In order to drive tank vehicles safely, remember: Drive smoothly – Because of the high center of gravity and the surge of the liquid, you must start, slow down and stop very smoothly. Also, make smooth turns and lane changes. Braking – If you must make a quick stop to avoid an accident, use controlled or stab braking.

How can you help control surge?

How can you help control surge? Keep a steady pressure on the brakes. DO NOT release too soon when coming to a stop. Brake far in advance of a stop and increase your following distance .
