1. You are very angry after an argument and about to drive. What should you know?
Show answer
Answer A: Strong emotions can impair judgment and attention much like alcohol
Anger, grief and stress pull attention inward and encourage risk taking. Give yourself time to settle down before getting behind the wheel.
-
2. How does driving on overinflated tires affect the vehicle?
Show answer
Answer D: It gives a harsher ride and a smaller contact patch
An overinflated tire bulges in the middle, so less rubber touches the road, grip suffers and the ride becomes hard. The center of the tread wears first.
-
3. Another driver is behaving aggressively toward you. What should you do?
Show answer
Answer D: Avoid eye contact, give them room to go on their way and do not respond to provocation
Responding to an aggressive driver escalates the conflict, while creating distance and refusing to engage takes you out of the situation. Report serious threats once you can do so safely.
-
4. Which surfaces usually offer less grip than the pavement around them when wet?
Show answer
Answer B: Painted markings, metal plates and bridge decks
Paint, steel and bridge decks all shed grip when wet or cold, so brake before you reach them rather than on top of them.
-
5. On dry pavement in good weather, what is the smallest following gap you should keep?
Show answer
Answer A: About three seconds behind the vehicle ahead
Three seconds is the accepted minimum on dry roads in good visibility, and the gap should be longer in poor conditions.
-
6. A child seat was in the car during a moderate crash. What should be done with it?
Show answer
Answer A: Replace it, because a seat that has been through a crash may be weakened
Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.
-
7. What do white lane lines painted between travel lanes indicate?
Show answer
Answer A: Traffic in the adjacent lane moves in the same direction as you
White markings separate lanes carrying traffic in the same direction and mark the right edge of the roadway.
-
8. You have just driven through a deep puddle and your brakes feel weak. What should you do?
Show answer
Answer D: Drive slowly while lightly applying the brakes until they dry and work normally
Wet brakes grip poorly and may pull to one side. Gentle braking at low speed generates heat that dries the pads and discs quickly.
-
9. You are already inside an intersection when you realize you should be in the lane beside you. What should you do?
Show answer
Answer C: Stay in your lane through the intersection and change lanes afterwards
Drivers in an intersection are watching for cross traffic and turning vehicles, so an unexpected sideways move there is easily missed.
-
10. On a long, straight highway you feel your attention fading. What helps you stay alert?
Show answer
Answer A: Keep your eyes moving, scan mirrors and signs, and take regular breaks
Staring at one point brings on highway hypnosis. Active scanning keeps the mind engaged, and a break every couple of hours restores alertness.
-
11. A signal beside a fire station stays dark until apparatus is about to leave, when it shows yellow and then red. What must a driver do?
Show answer
Answer B: Stop on the red and wait until the signal goes dark again
An emergency vehicle signal is a real traffic signal, so its red indication must be obeyed while the apparatus pulls out into the street.
-
12. You are stopped at a stop sign where your road ends at a two-way through street and you plan to turn left. What must you yield to?
Show answer
Answer B: Traffic from both directions and any pedestrians crossing
A left turn from the stem of a T crosses the near lane and joins the far one, so you give way to traffic in both directions and to pedestrians.
-
13. You find yourself in a lane that must turn, you wanted to go straight, and you cannot change lanes safely. What should you do?
Show answer
Answer D: Make the required turn and find another route
Going straight from a mandatory turn lane surprises everyone around you, while a wrong turn costs only a few extra minutes.
-
14. What maximum speed does the Missouri Driver Guide list for interstate highways, freeways and expressways inside urbanized areas?
Show answer
Answer B: 60 mph
Missouri lists 60 mph for interstates, freeways and expressways within urbanized areas, well below the rural interstate maximum, because interchanges and merging traffic are more frequent there.
-
15. You are about to change lanes to the left when you notice a vehicle already overtaking you in that lane. What should you do?
Show answer
Answer A: Hold your lane and your speed, and change only after that vehicle has gone by
A signal asks for space but does not create it, and the overtaking driver has nowhere to go if you move across.
-
16. A deer crosses the road in front of you and disappears into the trees. What should you expect?
Show answer
Answer B: That other deer are likely to follow it across the very same stretch of road
Deer usually move in groups, so one crossing the road is a warning that more may follow.
-
17. What should you do before you back out of your own driveway at home?
Show answer
Answer A: Walk around the vehicle and check behind it for children or objects
A small child, a bicycle or a toy can sit entirely inside the blind area behind a vehicle, and a walk-around is the only way to be sure it is clear.
-
18. What should you avoid when a hostile driver pulls alongside you?
Show answer
Answer A: Making eye contact, or answering the gestures in any way at all
Any response, including a look, encourages an aggressive driver, so give none and let the vehicle go.
-
19. What is Missouri's uniform maximum speed on roads outside an urbanized area that are not interstates, freeways, expressways or lettered routes?
Show answer
Answer A: 60 mph
All other roads and highways outside an urbanized area carry a 60 mph uniform maximum limit under Missouri law.
-
20. Where is the safest place for children under 13 to ride?
Show answer
Answer C: In the back seat
The back seat keeps children away from the force of a deploying front air bag and is farther from the most common impact area, which is why it is recommended through at least age 12.
-
21. Your vehicle does not have antilock brakes and you must stop quickly on a slippery road. What is the correct technique?
Show answer
Answer B: Apply the brakes firmly without locking the wheels, releasing slightly if they lock
Locked wheels slide and cannot steer. Squeezing the brakes to just short of lockup, and easing off if they lock, gives the shortest stop with control.
-
22. Why is being predictable an important part of driving safely?
Show answer
Answer A: Because other road users are able to plan around what you are doing
Other drivers make their decisions from what they expect you to do, so surprises are what produce collisions.
-
23. What is the default speed limit in any Missouri city, town or village when no sign is posted?
Show answer
Answer B: 25 mph
Missouri sets 25 mph as the speed limit in any city, town or village unless a sign posts a different limit.
-
24. A pedestrian steps off the curb without looking your way. What should you assume?
Show answer
Answer B: That the person has not seen you at all, and be ready to stop for them
Defensive driving means assuming you have not been seen until there is clear evidence that you have.
-
25. A city transit bus at a stop ahead of you switches on its left signal. What should you do?
Show answer
Answer D: Slow and let the bus pull back into traffic
A bus needs a long gap to rejoin traffic, and yielding to a signaling transit bus keeps the whole line of traffic moving safely.
