Tanker Practice Question 23

NTanker · Question 23

You should keep what kind of distance behind a tanker truck:

  • AStandard CDL following distance plus extra
  • BThe same as cars
  • CLess than passenger cars
  • DNone — it cannot stop

Correct answer: A. Standard CDL following distance plus extra

Why: Behind another tanker, leave room. Behind your own tanker's projected stopping distance, leave room. Always more than typical CMV distance.

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.
