1 / 10

You are approaching a highway curve in a tank vehicle. What is the safest way to handle the curve?

2 / 10

You are driving a partially filled tank vehicle on a slippery road and must stop at a red light. As you brake, you feel the liquid surge forward. What is the greatest immediate risk if the surge is strong?

The brakes will automatically lock.

The tank could collapse from the pressure.

The liquid will freeze inside the tank.

The truck could be pushed into the intersection.

3 / 10

You are driving a tank vehicle with baffles inside. What effect do the baffles have on the liquid’s movement during sudden stops?

They make the tank easier to clean.

They prevent the tank from rolling over in any situation.

They eliminate all liquid movement.

They help control forward and backward surge but do not prevent side-to-side surge.

4 / 10

You are driving a tank vehicle and must stop quickly to avoid a crash. What is the recommended braking technique to help control liquid surge?

Rely on the parking brake.

Pump the brakes rapidly.

Use controlled or stab braking.

Brake as hard as possible and release immediately.

5 / 10

You are driving a tank vehicle with a high center of gravity. What is a key risk you must manage when making turns or lane changes?

The tank will leak more easily.

The vehicle is more likely to roll over.

The tires will wear out faster.

The brakes will overheat quickly.

6 / 10

You are loading a tank vehicle with several compartments separated by bulkheads. What is the safest way to fill the compartments?

You should add water to dilute the liquid.

The tank must always be filled completely.

The tank may need to be only partially filled to stay within legal weight limits.

Dense liquids require no special consideration.

Leave enough space for the liquid to expand.

Only fill the tank halfway regardless of the liquid.

Add ice to the liquid to keep it cool.

Fill the tank completely to prevent sloshing.

9 / 10

You are driving a tank vehicle with baffles and must make a sharp turn. What specific hazard should you still be concerned about?

Baffles blocking the discharge valve.

Forward surge causing brake failure.

Side-to-side surge causing a rollover.

Liquid freezing in the tank.

10 / 10

You are hauling milk in a smooth bore (un-baffled) tanker. What special driving adjustment should you make when starting and stopping?

Rely on the tank's baffles to control movement.

Accelerate quickly to reduce surge.

Drive extremely cautiously and brake gently.

Stop as abruptly as possible to minimize sloshing.
