1. If you must abandon a vehicle stuck on the tracks with a train coming, why do you move toward the train and away at an angle?
Show answer
Answer D: Because debris from the impact is thrown forward, away from the train
A train pushes wreckage down the track ahead of it, so walking toward the train and off to the side keeps you out of the debris path.
-
2. Why are motorcycles so often missed by other drivers?
Show answer
Answer C: Their narrow shape is easily hidden in traffic
A motorcycle presents a narrow outline that disappears behind pillars, mirrors and other vehicles, and it is harder to judge its speed and distance.
-
3. You feel dizzy and get a headache while driving with the windows closed. What could be the cause and what should you do?
Show answer
Answer D: An exhaust leak letting carbon monoxide into the cabin, so open the windows and stop to get fresh air
Carbon monoxide is colorless and odorless, and headache, dizziness and drowsiness are early signs. Get fresh air at once and have the exhaust system inspected.
-
4. You arrive at an intersection where the traffic signals are completely dark after a power failure. What should you do?
Show answer
Answer A: Treat the intersection as an all-way stop and take turns
When a signal is dark or out of order, drivers on every approach must stop and proceed in turn, exactly as at a four-way stop.
-
5. When does Missouri law require headlights to be switched on?
Show answer
Answer D: Half an hour after sunset to half an hour before sunrise, and when wipers are used
Missouri requires headlights from half an hour after sunset until half an hour before sunrise, and any time weather conditions call for the windshield wipers.
-
6. The left-turn signal facing you shows a flashing yellow arrow. What does it mean?
Show answer
Answer C: You may turn left after yielding to oncoming traffic and to pedestrians
A flashing yellow arrow permits a left turn but gives no protection, so you must yield to oncoming vehicles and to people in the crosswalk.
-
7. May you exceed the posted speed limit in order to complete a pass?
Show answer
Answer C: No, the posted limit applies while you are passing too
The limit does not lift for passing; if you cannot complete the pass within it, there is not enough room and you should stay back.
-
8. Something rolls off the seat onto the floor while you are driving. What should you do?
Show answer
Answer C: Leave it where it is and pick it up after you stop somewhere safe
Reaching for an object pulls your eyes and your body away from the controls at exactly the wrong moment, and nothing on the floor is worth that risk.
-
9. A traffic signal is dark and you reach the intersection at the same moment as a vehicle on your right. Who goes first?
Show answer
Answer A: The vehicle on your right, as at any all-way stop
A dark signal is treated as an all-way stop, and the usual tie-breaker then applies: the vehicle on the right goes first.
-
10. A second, third or fourth class Missouri county sets a speed limit on a county road but posts no signs. What limit applies?
Show answer
Answer C: 50 mph
Such a county commission may set a limit of up to 55 mph if the road is properly signed; where no signs are posted the limit is 50 mph.
-
11. On a two-lane road, a solid yellow line runs on your side of the center while a broken yellow line runs on the other side. What does this mean?
Show answer
Answer D: You may not pass, although oncoming drivers may
Passing restrictions are read from the line closest to your own lane, so a solid yellow line on your side creates a no-passing zone for you alone.
-
12. When must a Missouri driver file an accident report with the Department of Revenue?
Show answer
Answer A: Within 30 days, if someone was uninsured and damage tops $500
Missouri requires an accident report within 30 days when the crash happened in the state, someone involved carried no liability insurance, and there was injury, death or property damage over $500.
-
13. The car ahead of you slows down for no reason that you can see. Should you pull out and pass?
Show answer
Answer B: No, find out why it is slowing before you commit to the other lane
A driver usually slows for something, such as a turn, a hazard or a pedestrian, and that something is often exactly where your pass would take you.
-
14. The light turns yellow when your front wheels are already past the stop line inside the intersection. What should you do?
Show answer
Answer B: Keep going and clear the intersection without speeding up
Once you are legally in the intersection the safest and correct action is to continue through and clear it, without accelerating.
-
15. Traffic ahead of you has stopped in your lane while the next lane is still moving. What is the first thing to do?
Show answer
Answer C: Slow down first and check the next lane before moving over
Braking is the action that keeps you from hitting the stopped traffic, and the lane change is only safe once you have looked.
-
16. A marked accessible space is signed as van accessible. What is different about it?
Show answer
Answer B: It has a wider aisle for a ramp or a lift to come out
The extra width beside the space is there so a side ramp or lift can deploy and a wheelchair can get clear of the vehicle.
-
17. Why does even a small reduction in speed matter so much where people are walking?
Show answer
Answer D: Because a pedestrian struck at a lower speed is far more likely to survive
The chance that a pedestrian survives falls steeply as impact speed rises, so a few miles per hour can decide the outcome.
-
18. On an undivided two-lane road you meet a school bus coming toward you with its red lights flashing and its stop arm out. What must you do?
Show answer
Answer C: Stop and wait until the red lights stop flashing
On an undivided road drivers in both directions must stop for a school bus loading or unloading, because children may cross in front of it.
-
19. The queue for an exit ramp has backed up into the right lane of the highway. What should you do if you want that exit?
Show answer
Answer B: Join the back of the queue in the lane instead of cutting in later
Passing a queue and forcing in at the front stops the whole line, and using the shoulder puts you where broken-down vehicles are expected to be.
-
20. How does a wet road change the distance you need to stop?
Show answer
Answer C: It lengthens it, so you need a much bigger gap ahead
Water between the tire and the road cuts grip, so braking distance grows and the gap that works on dry pavement is no longer enough.
-
21. A disabled vehicle is blocking your lane on a two-lane road with a single solid yellow line on your side. What should you do?
Show answer
Answer C: Wait until the oncoming lane is clear, then go around carefully
The solid line prohibits overtaking a moving vehicle, but in most states a driver may go around an obstruction such as a disabled vehicle once the oncoming lane is clear and the move can be made safely.
-
22. The divided highway ends warning sign means that
Show answer
Answer D: the median separating the directions ends and the road returns to two-way operation
Beyond this sign opposing traffic is no longer separated by a median, so the driver must keep right and expect vehicles approaching in the adjacent lane.
-
23. A traffic signal is displaying a flashing red light. How must you treat it?
Show answer
Answer D: Stop completely, then proceed when the way is clear
A flashing red carries the same meaning as a stop sign: come to a full stop, then go only when it is safe.
-
24. Your vehicle has daytime running lights. Why should you still switch on the headlights at dusk?
Show answer
Answer B: Daytime running lights usually do not light the tail lights, so you are hard to see from behind
On many vehicles the daytime running lights illuminate only the front. Without the headlight switch on, the rear of the vehicle stays dark and the dash may still look lit.
-
25. Why does the speed of the right-hand lane of a freeway change so often?
Show answer
Answer B: Vehicles entering and leaving the highway all use that lane
Entrance and exit ramps feed into the right lane, so traffic there is constantly slowing to leave or speeding up to join.
