Tanker Practice Question 36

NTanker · Question 36

Tank truck rollovers most often occur during:

• AHighway cruising
• BRamps, curves, and intersections at speeds the driver thought were safe
• CBacking up
• DFueling

Correct answer: B. Ramps, curves, and intersections at speeds the driver thought were safe

Why: Most rollovers happen during routine maneuvers — exit ramps, intersections, and curves — at speeds the driver believed were safe based on car-driver intuition.

How this question fits the Tanker test

Liquid surge can push a vehicle through an intersection or roll it on a curve. The Tanker endorsement specifically addresses how unbaffled and partially full tanks behave differently from rigid loads.

Study technique for this topic

Know the difference between baffled, unbaffled, and compartmented tanks, the safe outage percentage for liquid expansion, and why front-to-back surge is more dangerous than side-to-side surge.
