CDL · Tank vehicles

Which term describes the dividers between tank compartments that have holes or openings in them?

Correct answer: Baffles.

Answer options

  1. ABaffles Correct
  2. BBulkheads
  3. CSmooth bores

Why

Baffles contain holes, so liquid can still flow from one section to another, but they reduce the front-to-back surge that builds up when the vehicle speeds up or brakes. Bulkheads, by contrast, are solid and seal each compartment off completely.
