Review all 5 questions with answers

  1. For a tanker without ABS, which emergency braking methods does the handbook describe?

    Correct answer: Controlled or stab braking

    For a tanker without ABS, section 8.3.2 describes controlled or stab braking for an emergency stop. Sudden steering while braking can overturn a tanker. This question does not instruct drivers to pump functioning ABS brakes.

  2. What is the recommended speed-control sequence for a curve in a tank vehicle?

    Correct answer: Slow before the curve, then accelerate slightly through it

    Reduce to a safe speed before entering the curve, then use slight acceleration through it without exceeding a safe speed. The posted curve speed may be too fast for a tanker.

  3. Which tanker may require more stopping distance than many drivers expect?

    Correct answer: An empty tank vehicle

    An empty tanker can need more stopping distance than a loaded one. Wet pavement further increases stopping distance; allow extra space instead of assuming an empty vehicle will stop quickly.

  4. Which action can cause a tank vehicle to skid?

    Correct answer: Oversteering, hard acceleration, or excessive braking

    Abrupt steering, acceleration, and braking can break tire traction.

  5. What can happen if the drive or trailer wheels of a tank trailer begin to skid?

    Correct answer: The combination may jackknife

    A skid at the drive or trailer wheels can start a jackknife, so the driver must restore wheel traction.
