Practice Questions & Answers.
1. How do you find out how many seconds of following distance space you have? - CORRECT ANSWER To
know how much space you have, wait until the vehicle ahead passes a shadow on the road, a pavement
marking, or some other clear landmark. Then count off the seconds like this: "one thousand- and-one,
one thousand-and-two" and so on, until you reach the same spot. Compare your count with the rule of
one second for every ten feet of length.
2. If you are driving a 30-foot vehicle at 55 mph, how many seconds of following distance should you
allow? - CORRECT ANSWER 4.
How much space should you keep in front of you? One good rule says you need at least one second for
each 10 feet of vehicle length at speeds below 40 mph. At greater speeds, you must add 1 second for
safety. For example, if you are driving a 40-foot vehicle, you should leave 4 seconds between you and
the vehicle ahead. In a 60-foot rig, you'll need 6 seconds. Over 40 mph, you'd need 5 seconds for a 40-
foot vehicle and 7 seconds for a 60-foot vehicle. See Figure 2.12.
3. You should decrease your following distance if somebody is following you too closely. True or False? -
CORRECT ANSWER False.
Increase your following distance. Opening up room in front of you will help you to avoid having to make
sudden speed or direction changes. It also makes it easier for the tailgater to get around you.
4. If you swing wide to the left before turning right, another driver may try to pass you on the right. True
or False? - CORRECT ANSWER True.
turn wide as you complete the turn. Keep the rear of your vehicle close to the curb. This will stop other
drivers from passing you on the right. Don't turn wide to the left as you start the turn. A following driver
may think you are turning left and try to pass you on the right. You may crash into the other vehicle as
you complete your turn.
