Review all 3 questions with answers

  1. A large vehicle ahead blocks your view of the road. How should you change your following gap?

    Correct answer: Increase it so you have more room and time to respond.

    A blocked view makes developing hazards harder to see. The manual calls for additional following space rather than relying only on the vehicle ahead.

  2. What makes up total stopping distance after a driver notices a hazard?

    Correct answer: The distance traveled while reacting plus the distance needed to brake.

    You travel before the brakes begin slowing the car as well as during braking. Speed, road surface, tires and attention affect the space needed.

  3. You are already on an interstate and notice a car approaching the end of an entrance ramp. A lane change away from it is safe and permitted. Which action can help traffic merge smoothly?

    Correct answer: Signal and move over safely to make room.

    The guide recommends making room for entering vehicles when a lane change is safe. Check surrounding traffic first; cooperation does not justify an abrupt move or stopping a through lane.
