A driver is turning left at an intersection with a partially loaded smooth-bore tanker. What unique hazard does a smooth-bore tank create compared to a baffled tank in this situation?

A driver is turning left at an intersection

Multiple choice — select the best answer

AThe tank is lighter, so the steering is harder to control
BThe absence of baffles lowers the center of gravity, making turns more stable
CLiquid shifts fully to one side without restriction, creating severe side-to-side surge and increasing rollover risk
DSmooth-bore tanks develop higher internal pressure during turns

✓ Correct answer: C. Liquid shifts fully to one side without restriction, creating severe side-to-side surge and increasing rollover risk Without baffles or bulkheads to slow lateral flow, a smooth-bore tank allows all free liquid to rush unimpeded to the outward side of a turn, dramatically raising the center of gravity and rollover risk.
