    Correct answer: Perception, reaction and braking distances

    The vehicle travels while you recognize a hazard, while you respond, and while the brakes slow it to a stop. This question concerns the basic model, not the separate air-brake discussion.

  98. A newer streamlined truck climbed a hill in a relatively high gear. Should you automatically use that same gear to descend?

    Correct answer: No, the descent may require a lower gear suited to that truck and grade

    Reduced drag and different engine performance can make the old same-gear rule unsuitable. Select the correct low gear before descending.

  99. Two legal parking spaces are equally suitable for your truck. One allows a forward exit; the other requires backing into traffic. Which is preferable?

  100. Why check the rated capacity of a coupling device before assigning a load?
