1. Your loaded vehicle weighs more than the figure shown on a posted weight limit sign. What must you do?
Show answer
Answer D: Find another route, because crossing is not permitted
A posted weight limit is a legal maximum, not advice, so an overweight vehicle has to take a different route.
-
2. A sign reads MINIMUM SPEED 40. What does it require of a driver?
Show answer
Answer C: Not to drive below that speed when conditions allow
A minimum speed limit keeps unnecessarily slow vehicles from obstructing traffic, but it never overrides the duty to slow down for weather or congestion.
-
3. A large electronic advertising sign beside the road catches your eye. What should you do?
Show answer
Answer A: Glance briefly and return your eyes to the road
Bright changing displays are designed to hold attention, so treat them like any roadside object and give them no more than a brief glance.
-
4. A SHOULDER DROP OFF sign warns that
Show answer
Answer B: there is a step down from the pavement to the shoulder
The sign is used where the edge of the pavement stands several inches above the shoulder, which can grab a wheel and pull the vehicle sideways.
-
5. A train has just cleared a crossing that carries two sets of tracks. What should you do?
Show answer
Answer B: Wait and look both ways for a second train
A passing train hides a second train on the other track, so wait until the signals stop and you can see that both tracks are clear.
-
6. Your light is green but the traffic beyond the intersection is stopped and there is no room on the far side. What should you do?
Show answer
Answer A: Wait behind the line until you can clear the far side
Entering an intersection you cannot clear blocks the cross traffic when their signal turns green, so you wait behind the line.
-
7. Where should a touring rider keep the rain suit?
Show answer
Answer B: Somewhere it can be reached quickly without unpacking everything
Rain gear only helps if you can get to it before you are soaked, so pack it where a quick roadside stop is enough to reach it.
-
8. Besides a chemical test, what else supports an impaired driving charge?
Show answer
Answer B: The officer's observations of the driving and the driver
Weaving, slow responses, speech and balance observed by the officer are evidence in their own right, which is why a driver can be charged on behavior alone.
-
9. What must a driver be prepared to do at the point this sign refers to?
Show answer
Answer D: Turn left or right, because the road being traveled ends there
The road ends at another roadway, so the driver must slow, give way to traffic on the through road and turn in one direction or the other.
-
10. How should a group plan its rest stops on a long day?
Show answer
Answer A: Around the rider who tires first, with breaks before anyone is worn out
Fatigue destroys judgment long before a rider admits to it, so the break schedule follows the least rested rider rather than the strongest one.
-
11. Where among these is parking specifically prohibited?
Show answer
Answer A: On a bridge, in a tunnel or on railroad tracks
Bridges and tunnels have no safe refuge and cannot be widened, and a vehicle left on railroad tracks cannot be avoided by an approaching train.
-
12. A black and white regulatory sign facing traffic at a divided section reads KEEP LEFT. What does it require?
Show answer
Answer D: Passing the island or obstruction on its left side
Keep Left is posted at an island or obstruction that traffic must pass on the left, which is the opposite of the far more common Keep Right situation.
-
13. A yellow sign reads SOFT SHOULDER. What is it telling you?
Show answer
Answer C: The shoulder may not carry the weight of a vehicle
A soft shoulder is unpaved and can let a wheel sink, so a driver who leaves the pavement there may lose control or become stuck.
-
14. Two people drink the same amount of alcohol at the same time. Why might their blood alcohol concentrations differ?
Show answer
Answer C: Body weight, gender and food in the stomach affect the concentration
Smaller people and, on average, women reach higher concentrations from the same amount of alcohol, and an empty stomach speeds absorption. Counting drinks alone does not tell you your level.
-
15. Besides 12 points in 12 months, which totals revoke a Missouri driving privilege for one year?
Show answer
Answer C: 18 points in 24 months or 24 points in 36 months
Missouri revokes a driving privilege for one year at 12 points in 12 months, 18 points in 24 months, or 24 points in 36 months.
-
16. 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.
-
17. A traffic signal separates you from the rest of your group. What should you do?
Show answer
Answer B: Continue at a safe and legal pace and rejoin the group farther along
Staying with a group never justifies breaking a traffic law, so a separated rider proceeds normally and the group regroups at a planned point.
-
18. You are ready to pull out of a parallel parking space into the traffic lane. What should you do?
Show answer
Answer C: Signal, check the mirror and blind spot, and wait for a gap
A driver leaving a parking space must yield to traffic already in the lane, so signal, look for the gap and only then move out.
-
19. How does braking distance change if you double your speed?
Show answer
Answer D: It grows much more than twice as long
Braking distance increases with the square of speed, so doubling speed roughly quadruples the distance needed to stop.
-
20. Which facility does this sign direct a traveler toward?
Show answer
Answer B: A hospital offering emergency care
This is the standard marker for medical care, used to lead a traveler to a hospital where emergency treatment is available.
-
21. A rectangular marker with alternating black and retroreflective yellow stripes set at a slant is used to
Show answer
Answer C: mark an obstruction, with the stripes sloping down toward the side on which traffic should pass
This striped panel is an object marker, and the direction in which the stripes slope shows the driver which side of the obstruction to pass on.
-
22. Why is a drive chain adjusted with too little slack a problem?
Show answer
Answer A: It strains the chain, the sprockets and the output shaft bearings
Suspension movement changes the distance between the sprockets, so a chain pulled tight at rest is stretched hard over bumps and wears everything it touches.
-
23. Which common non-prescription medicine is most likely to make a driver drowsy?
Show answer
Answer C: A cold or allergy remedy containing an antihistamine
Antihistamines in cold and allergy remedies are a leading cause of drowsiness behind the wheel, which is why the label carries a warning.
-
24. Your motorcycle has a grab rail behind the passenger seat. What should the passenger know about using it?
Show answer
Answer C: It is fine to hold, but they must still brace against acceleration
A rail behind the passenger gives a secure grip but does nothing to stop them sliding backward, so they still need to expect the machine to pull away.
-
25. Which Missouri Department of Transportation vehicles are covered by the move over law?
Show answer
Answer A: Those marked as emergency response or motorist assistance
A vehicle owned by the state highways and transportation commission qualifies when it is marked as a department of transportation emergency response or motorist assistance vehicle.
