A driver is hauling a bulkheaded tank with four equal compartments, each filled to 90% capacity with different liquid products. How does the bulkhead design change the surge dynamic compared to a single-chamber tank of the same total volume at the same average fill level?

ASurge is eliminated entirely because bulkheads block all liquid movement
BBulkheads convert front-to-back surge into side-to-side surge, worsening cornering stability
CSurge within each compartment is independent and smaller in magnitude, but multiple compartments can still produce additive handling forces
DSurge is identical to a single-chamber tank because total liquid mass is the same
✓ Correct answer: C. Surge within each compartment is independent and smaller in magnitude, but multiple compartments can still produce additive handling forcesEach bulkheaded compartment contains its own smaller surge, but the CDL manual notes drivers must still manage speed because multiple simultaneous surges across compartments can combine to challenge vehicle stability.
