1. You are turning left from a divided highway through a median opening into a business on the other side. Who has the right of way?
Show answer
Answer C: The traffic on the roadway you are crossing
Turning through a median opening means crossing the opposite roadway, so you yield to all traffic on it before you go.
-
2. Why is a shoulder check especially important on a road with motorcycles and bicycles?
Show answer
Answer D: A narrow vehicle can disappear completely in the blind spot
A motorcycle or a bicycle is small enough to be hidden entirely by a door pillar or by the blind spot the mirrors do not cover.
-
3. A broken white line separates your lane from the lane beside it. What does it indicate?
Show answer
Answer C: Both lanes carry traffic in the same direction and lane changes are permitted
White lines separate lanes of traffic moving in the same direction, and a broken white line means changing lanes across it is permitted when it is safe.
-
4. Who may set a Missouri state highway speed limit above or below the uniform maximum, and what ceiling applies?
Show answer
Answer C: The highways and transportation commission, up to 75 mph
The state highways and transportation commission may raise or lower a limit on the recommendation of the Department of Transportation, but no Missouri speed limit may be set above 75 mph.
-
5. What causes the side to side motion a rider feels when crossing a steel grid deck or rain grooves?
Show answer
Answer C: The tires following the ridges and grooves, which is normal and harmless
The tread follows the pattern in the surface, which produces a wandering feel. The motorcycle is not out of control, so relax on the bars and hold your speed.
-
6. You have a green light at a school crossing, but the crossing guard steps out and holds up a stop sign toward you. What must you do?
Show answer
Answer A: Stop, because the crossing guard controls this crossing and outranks the signal
Directions from a crossing guard or a police officer take priority over signals and signs.
-
7. You arrive at an intersection where the traffic signal is completely dark because of a power failure. How should you proceed?
Show answer
Answer C: Treat the intersection as an all-way stop
When a signal shows no indication at all, drivers on every approach must stop and then take turns, exactly as at an all-way stop.
-
8. How should you handle a prescription or over the counter medicine before driving?
Show answer
Answer D: Read the label and ask a pharmacist or doctor whether it affects driving
Many common medicines, including allergy and cold remedies, cause drowsiness or slowed reactions, and the label or a pharmacist can tell you whether driving is safe.
-
9. An oncoming driver flashes their headlights while you are waiting to turn left. What should you do?
Show answer
Answer D: Judge the situation yourself, since the flash may mean something else
A flash is not a legal signal and may mean many things, so the decision to turn stays yours and must be based on what you can see.
-
10. A driver is following you far too closely. What is the best response?
Show answer
Answer D: Increase your own following distance and let the driver pass when it is safe
More room ahead of you means you can slow gradually instead of braking hard, which reduces the chance of being struck from behind, and letting the driver by removes the problem entirely.
-
11. A bee gets inside your jacket while you are riding. What is the recommended action?
Show answer
Answer B: Pull off the road and stop before you try to deal with the insect
Being stung hurts, but losing control while swatting hurts much more, so ride to a safe place, stop and then deal with the insect.
-
12. The blue signs mounted before a freeway interchange that carry the logos of individual businesses are
Show answer
Answer C: specific service signs, which show the brands available at that exit
Specific service signs, often called logo signs, list eligible businesses for categories such as gas, food, lodging, camping, attractions and 24-hour pharmacies at the upcoming interchange.
-
13. The street you are turning right onto has a bike lane along its right edge. Where should your vehicle end up?
Show answer
Answer B: In the first traffic lane to the left of the bike lane
A bike lane is not a travel lane for motor vehicles, so the nearest lane you may finish a right turn in is the first general traffic lane beside it.
-
14. Why do safety agencies put head protection first among riding gear?
Show answer
Answer A: Because head injuries are the leading cause of death in motorcycle crashes
Head injury is the most common cause of death in motorcycle crashes, which is why a certified helmet is the single most important piece of gear.
-
15. You are driving at night through heavy falling snow. Which headlight setting works better and why?
Show answer
Answer C: Low beams, because high beams bounce off the falling flakes back at you
Falling snow reflects light the way fog does, so high beams build a white wall of glare while low beams still give a usable view.
-
16. Which clue tells you that a parked vehicle is about to pull into traffic?
Show answer
Answer D: Exhaust smoke, brake lights, front wheels turned out or a driver in the seat
A running engine, lit brake lights, turned wheels or a person behind the wheel all mean the vehicle may move. Slow down and give it room.
-
17. Why is it worth planning your route before a long drive?
Show answer
Answer B: So that you are not reading a map or a screen while the car is moving
A driver who knows the route is not navigating at the wheel, which is one of the commonest sources of distraction.
-
18. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
19. You are waiting to turn and the traffic ahead has stopped. Where must you not come to rest?
Show answer
Answer D: On the crosswalk, which people need in order to cross the street
Stopping on a crosswalk forces pedestrians out into the traffic lanes to get around you, so you hold back before it instead.
-
20. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
-
21. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
22. A fire truck with lights and siren has just passed you and is heading down the same road. How closely may you follow it?
Show answer
Answer B: Well back, because following a responding emergency vehicle closely is illegal
Following a responding emergency vehicle closely is prohibited; the exact minimum distance is set by each state, so stay far enough back to keep the scene and other responders clear.
-
23. Alcohol is classified as which kind of drug?
Show answer
Answer B: A depressant that slows the central nervous system
As a depressant, alcohol slows the brain and nervous system, which lengthens reaction time and dulls the coordination that driving depends on.
-
24. 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.
-
25. 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.
