  1. 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.

  2. Another driver makes an angry gesture after a traffic disagreement. What should you do?

    Correct answer: Avoid engaging and create safe separation.

    Do not turn a mistake or disagreement into a confrontation. Maintain control, avoid retaliation and separate when safe.

  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.
