1. The crossing gates begin to lower while your vehicle is still on the railroad tracks. What should you do?
Show answer
Answer B: Keep going forward and push through the gate if it should block your way
Gates are made to break away, and driving forward off the tracks is far safer than staying between them or backing up.
-
2. You have fitted the small temporary spare tire after a flat. What should you keep in mind?
Show answer
Answer C: It is meant for low speed and short distances until the regular tire is repaired
Compact spares have limited grip, handling and durability. Follow the speed and distance limits printed on the tire and get the regular tire fixed soon.
-
3. How often should you check your mirrors while driving?
Show answer
Answer C: Every few seconds, so you always know what is around you
Traffic behind and beside you changes constantly. Frequent, brief mirror checks keep a picture of your surroundings current so nothing surprises you.
-
4. You have turned onto a street and see parked cars facing you and headlights coming toward you. What has probably happened?
Show answer
Answer C: You have turned the wrong way onto a one-way street
Vehicles parked facing you and headlights approaching in your lane are the classic signs of driving against the flow on a one-way street.
-
5. You are driving through a long curve on a road with two lanes in your direction. What is correct?
Show answer
Answer A: Stay within your own lane all the way through, adjusting speed before you enter
Wandering out of your lane in a curve puts you into the path of a vehicle you cannot see, and the slowing belongs before the curve rather than in it.
-
6. How does alcohol typically affect a driver's vision?
Show answer
Answer D: It blurs vision, weakens night vision and narrows attention to the sides
Alcohol slows the eye muscles and the brain's processing of what is seen, degrading focus, night vision, depth perception and awareness of movement at the edges of the field of view.
-
7. Four vehicles reach a four-way stop from all four directions at the same instant. How is the deadlock resolved?
Show answer
Answer C: Each driver yields to the vehicle on the right and they go one by one
Yielding to the right applies to every driver, so the group untangles itself as drivers take turns rather than moving together.
-
8. Which color scheme is standard for the drums and barricades that channel traffic through a work zone?
Show answer
Answer C: Alternating orange and white retroreflective stripes
Drums and barricades carry alternating orange and white retroreflective stripes, and the traffic cones used in the same zones are predominantly orange.
-
9. Which of these is announced with the same family of signs as the facility shown here?
Show answer
Answer A: A rest area for travelers
A rest area belongs to the same motorist service series, which points travelers toward facilities such as fuel, food, lodging and medical care.
-
10. Some drivers believe they can multitask while driving. What does research show?
Show answer
Answer C: The brain switches rapidly between tasks and driving performance suffers
The brain does not truly do two attention-demanding tasks at once; it alternates between them, and the driving task gets less attention each time.
-
11. A vehicle ahead of you displays a reflective orange triangle on its rear. What does that emblem tell you?
Show answer
Answer B: The vehicle is built to travel at 25 mph or less
The orange triangle is the slow moving vehicle emblem used on farm and construction equipment designed for 25 mph or less, warning you that you are closing on it much faster than it appears.
-
12. Why is passing on a curve prohibited even when the traffic seems light?
Show answer
Answer C: You cannot see far enough around it to know the lane is clear
A pass is only as safe as the distance you can see, and a curve hides the very lane the maneuver uses.
-
13. Why do bridges and overpasses deserve extra caution when temperatures are near freezing?
Show answer
Answer A: They lose heat from above and below, so they ice over before the surrounding road
A bridge deck is exposed to cold air on both surfaces and has no ground beneath it to hold heat, so ice can form there while the connecting road is still only wet.
-
14. After a crash, what information should you exchange with the other driver?
Show answer
Answer B: Name, address, driver license, vehicle registration and insurance details
Identification, registration and insurance information are what the other party and the insurers need. Sensitive financial details are never required.
-
15. A white diamond symbol is painted in a highway lane. What does it identify?
Show answer
Answer C: A lane reserved for high-occupancy vehicles
The diamond symbol marks a preferential lane, most often one reserved for vehicles carrying a minimum number of occupants.
-
16. You have a green light and are turning right while people are crossing the street you want to enter. Who goes first?
Show answer
Answer B: The pedestrians, and you wait until they are clear of your path
A green light permits the turn but does not remove the duty to yield to pedestrians already crossing the street you are turning into.
-
17. You are driving on a rural road with no sidewalk. Where should you expect to meet pedestrians?
Show answer
Answer A: Walking toward you on your side of the road
Where there is no sidewalk, pedestrians are taught to walk facing traffic, so they appear on your side of the road coming toward you.
-
18. At an intersection that uses a lagging left turn, when is the left-turn arrow displayed?
Show answer
Answer B: After the through movement has run
A lagging left turn phase runs at the end of the green rather than the start, so a driver waiting to turn should not assume the arrow has been missed.
-
19. You know in advance that you will be drinking at an event. What is the most reliable plan?
Show answer
Answer A: Arrange a driver who will not drink, or another way home, before the event begins
A decision made before drinking is not affected by alcohol, while judging your own fitness afterward relies on the very ability alcohol impairs first.
-
20. School warning signs use which background and legend colors?
Show answer
Answer A: A black legend and border on a fluorescent yellow-green background
School warning signs carry a black legend and border on a fluorescent yellow-green background, a shade chosen so they stand out from ordinary yellow warning signs.
-
21. How many points does Missouri assess for a conviction of careless and imprudent driving?
Show answer
Answer C: 4 points
The Missouri point schedule assigns 4 points to careless and imprudent driving, compared with 3 points for speeding.
-
22. You and the driver facing you both have stop signs at a two-way stop. You are going straight and that driver is turning left. Who has the right of way?
Show answer
Answer B: You do, and the turning driver must wait
Between two opposing drivers who both stopped, the one going straight goes first and the left-turning driver yields.
-
23. You reach a stop-controlled intersection at the same time as a driver on your left, but that driver is already moving through the crossing. Who goes first?
Show answer
Answer C: The driver who is already inside the intersection
A vehicle already in the intersection has the right of way, and the rule about yielding to the right applies only before anyone has entered.
-
24. A sign with a yellow background and a black legend generally conveys
Show answer
Answer B: a general warning
Yellow is the background color used for general warning signs, so a yellow sign tells the driver to expect something ahead rather than to obey a rule.
-
25. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
