🎯 Practice by Topic
Inspecting Tank Vehicles
Inspecting a tank vehicle: checking for leaks (you cannot drive a leaking tank), and checking the special-purpose and emergency equipment tank vehicles carry (vapor-recovery, special cut-off systems, etc.).
Driving Tank Vehicles
Why tank vehicles are harder to drive: the high center of gravity (rollover risk), the danger of liquid surge in a partially filled tank, bulkheads vs baffled vs smooth-bore (un-baffled) tanks, outage (room for the liquid to expand), and how much you can load.
Safe Driving Rules
Driving a tank vehicle safely: drive smoothly, control surge when braking (brake early, keep extra following distance), slow down for curves below the posted speed, allow for a longer stopping distance, and recover from skids.
