3. The __________________ says that a driver should always operate his or her vehicle at a
speed that is reasonable and prudent for existing conditions.
4. _______________________is the force that pushes you back into your seat when your car
accelerates.
5. _____________________ distance is the distance traveled by your vehicle during the time it
takes you to identify the need to stop and react to the braking situation.

Short Answer:
1. How should you apply the brakes on a vehicle equipped with an antilock braking system?
2. What are the advantages and disadvantages of crowned roads?
3. In terms of the natural laws that act on cars and drivers, what role do safety belts play?
4. What factors should you consider in deciding how fast to drive?
5. What might happen if you understeer going around a curve?
Critical Thinking:
1. Your friend, who usually drives a small compact car, takes you on a “test ride” in a large sport utility vehicle that
she is considering purchasing. She begins to drive aggressively to “put it to the test.” What are some of the risks
you both face even if few cars are on the road? What specific risks may be associated with negotiating curves
and braking?
2. You have been “elected” to drive several friends back down the mountain after a full day of skiing. It is late in
the afternoon when you begin your trio down the steep, treacherous grade. What factors do you need to
consider when deciding how closely to follow a large truck in front of you that you are unable to pass?
