1. Even though medical marijuana is legal in Missouri, driving under its influence is:
Show answer & explanation
Correct answer: Never legal or safe
Even though medical marijuana was approved by Missouri voters, it is never legal or safe to drive while under its influence. Marijuana impairs judgment of time and distance, decreases coordination, and worsens reaction time.
2. Which license or endorsement do you need to operate a motorcycle on public roadways in Missouri?
Show answer & explanation
Correct answer: A Class M license or a license with the Motorcycle (M) endorsement
To operate a motorcycle or motortricycle on public roadways you must have a Class M license or a driver license carrying the M endorsement. This requires passing the Class F and Class M written tests plus the vision, road-sign, and motorcycle skills tests.
3. When you leave your parked vehicle out of your sight, you should:
Show answer & explanation
Correct answer: Never leave the keys in it, and lock the doors
Never leave the keys in a parked vehicle. Lock the doors whenever you leave your vehicle if it will be out of your sight at any time.
4. Your driving privilege will be REVOKED for one year if you accumulate:
Show answer & explanation
Correct answer: 12 or more points in 12 months
A one-year revocation results from 12 or more points in 12 months, 18 or more points in 24 months, or 24 or more points in 36 months.
5. At an intersection with no stop sign or traffic signal, who must you yield to?
Show answer & explanation
Correct answer: Vehicles coming from the right
At an uncontrolled intersection (no stop sign or traffic signal), drivers must yield to vehicles coming from the right. Roundabouts are the exception — there you yield to traffic already in the circle.
6. If you miss your exit on a controlled-access highway, you should:
Show answer & explanation
Correct answer: Continue to the next exit and come back
If you miss your exit, do not stop, back up, or try to turn around on the highway. Get off at the next exit and come back to the one you missed.
7. The large blind spots around a truck or bus where your car cannot be seen are called:
Show answer & explanation
Correct answer: The "No-Zone"
A truck or bus has blind spots on each side, in the rear, and in the front where a car cannot be seen. These blind spots are called the "No-Zone." Do not drive in the No-Zone except when absolutely necessary.
8. What does a flashing yellow traffic light tell you to do?
Show answer & explanation
Correct answer: Slow down and proceed with caution
A flashing yellow light tells you to slow down and proceed with caution. Unlike a flashing red, it does not require you to stop.
9. Which of these will INCREASE the distance you need to stop your vehicle?
Show answer & explanation
Correct answer: Driving fast, being very tired, or having bad brakes
If you are driving fast, are very tired, or your vehicle has bad brakes, you will need more space to stop. Stay alert — the standard reaction-distance figures assume you react within one and one-half seconds.
10. You are turning from a two-way street onto a one-way street with two lanes. Which lane may you enter?
Show answer & explanation
Correct answer: The left lane or the right lane, whichever is free of traffic
When turning onto a one-way street with two lanes, you may turn into its left lane or right lane, whichever is free of traffic. Begin the turn with your left wheel as close as possible to the yellow dividing line.
11. Over-the-counter cold and allergy medicines can:
Show answer & explanation
Correct answer: Make you drowsy and affect your driving ability
All medications, both prescription and over-the-counter, can impair driving even when taken as directed. Any drug that "may cause drowsiness or dizziness" is one you should not take before driving, and you should never mix medications with alcohol.
12. When you drive in Missouri, what must you do with your driver license or permit?
Show answer & explanation
Correct answer: Carry it with you and present it if a law enforcement officer asks to see it
You are required to carry your driver license or permit when you drive and must present it to any law enforcement officer who asks. It is against the law to let anyone else use your license or permit.
13. On a one-way street, where may you normally park?
Show answer & explanation
Correct answer: On either the right or the left side of the street
On one-way streets you may normally park on either the right or the left side of the street, unless signs or curb markings say otherwise.
14. If you drive for one full year without getting new points on your record, your remaining points are:
Show answer & explanation
Correct answer: Reduced by one-third
Points fade with clean driving: remaining points are reduced by one-third after one year, by one-half after two years, and to zero after three years — though certain convictions stay listed on the record permanently.
15. If a traffic officer signals you to stop at a green light, what should you do?
Show answer & explanation
Correct answer: Obey the officer and stop — directions from a traffic officer override signs and signals
You must obey traffic officers at all times. If an officer directs you to do something different from what the signs or signals show, follow the officer’s directions.
16. To avoid "highway hypnosis" — feeling drowsy and unaware on long, monotonous drives — you should:
Show answer & explanation
Correct answer: Keep your eyes moving and watch the traffic and signs around you
Highway hypnosis is caused by the sameness of the road and traffic. Avoid it by constantly moving your eyes and watching the traffic and signs around you. If you feel sleepy, pull off the highway.
17. If you are behind a large truck and cannot see the driver in the truck’s mirrors, it means:
Show answer & explanation
Correct answer: The truck driver cannot see you
If you are driving behind a truck or bus and cannot see the driver in the side mirrors, the driver of that vehicle cannot see you. Leave large vehicles a cushion of safety.
18. A traffic signal that is completely dark and not working should be treated as:
Show answer & explanation
Correct answer: A four-way stop
Dark signals, or traffic signals that are not working, operate as a four-way stop. Every direction must stop and take turns proceeding.
19. Another driver is tailgating you and there is no right lane to move into. What should you do?
Show answer & explanation
Correct answer: Wait until the road ahead is clear, then reduce speed slowly to encourage the tailgater to go around
If you are tailgated and there is a right lane, move over. If not, wait until the road ahead is clear and reduce speed slowly. Never slow down quickly — that only increases your risk of being hit from behind.
20. After you complete a turn or small lane change, why should you check your turn signal?
Show answer & explanation
Correct answer: After small turns the signal may not cancel by itself, and a stuck signal misleads other drivers
After a turn or lane change, make sure your signal is off. After small turns it may not click off by itself, and other drivers might think you plan to turn again.
