Tanker Practice Test Flashcards

Which factor makes tank vehicles more likely to roll over than other trucks?

Answer: High center of gravity and liquid surge

The combination of a high center of gravity and shifting liquid makes tankers especially rollover-prone.

What should you check about the tank's leak before and during a trip?

Answer: Inspect for leaks both before and during the trip

You should inspect for leaks during the pre-trip and continue watching for them along the route.

Why is it dangerous to oversteer or jerk the wheel in a loaded tanker?

Answer: It can cause the liquid to surge and tip the vehicle

Sharp steering inputs can trigger surge that shifts weight suddenly and rolls the tanker.

What does the term 'bulk packaging' generally mean for tankers?

Answer: Liquid or gas carried directly in the tank without inner containers

Bulk packaging means the product is loaded directly into the tank rather than in individual containers.

When driving a tanker on wet roads, you should reduce your speed by about how much compared to dry roads?

Answer: One-third

On wet roads you should cut speed by about a third to maintain control of a heavy, surging load.

What is the purpose of vents on a tank vehicle?

Answer: To allow pressure equalization and prevent tank damage

Vents let air in and out so the tank can equalize pressure and avoid collapse or rupture.

If your tanker's brakes get wet after driving through deep water, what should you do?

Answer: Apply light pressure while driving slowly to dry them

Gently applying the brakes while moving slowly creates friction heat that dries them out.
