What difference do baffles in the cargo tanks make to the way a tanker drives?

Correct answer: They noticeably reduce surge toward the front and rear.

Answer options

  1. AThey make the tanker feel heavier than its actual weight
  2. BThey make almost no difference in how the tanker handles
  3. CThey noticeably reduce surge toward the front and rear Correct

Why

Because the liquid has to squeeze through the openings in each baffle, it cannot slam as hard toward the front when you brake or toward the rear when you accelerate. Baffles do not make the truck feel heavier, and they do little against side-to-side surge.
