1. What is the licensing consequence of a second Minor in Possession conviction in Missouri?
Show answer

Missouri suspends for 30 days on a first Minor in Possession conviction, 90 days on a second, and revokes for one year on a third.
-
2. What is the eligible age for a Missouri Class M motorcycle license?
Show answer
Answer B: 16 years old
Missouri sets the eligible age for the Class M license at 16, and graduated driver license requirements still apply to applicants between 16 and 18.
-
3. Does Missouri's move over law protect a tow truck stopped at the roadside?
Show answer
Answer D: Yes, wreckers and tow trucks count as emergency vehicles
Missouri's definition of an emergency vehicle includes any wrecker or tow truck, so the move over duty applies to them.
-
4. What happens when alcohol is combined with another drug that also affects the nervous system?
Show answer
Answer B: Impairment is often far greater than either one alone would produce
Combined substances can multiply each other's effects, producing impairment well beyond what a driver would expect from either one taken separately.
-
5. You want to pass on a two-lane road where several people are walking on the narrow shoulder ahead. What should you consider?
Show answer
Answer D: There is no escape room if the pass goes wrong, so wait for a better place
A pass depends on having somewhere to go if it goes wrong, and a shoulder occupied by pedestrians removes that option for both vehicles.
-
6. You are turning left out of a driveway onto a busy two-way street. What must you do?
Show answer
Answer D: Wait for a gap in both directions before you start to move
The turn crosses one direction of traffic and joins the other, so you need a gap in both before leaving the driveway rather than stopping across a lane.
-
7. Why should the leader of a group signal turns and lane changes early?
Show answer
Answer D: So the message has time to reach the riders at the back of the group
An early signal gives the whole formation, including the riders far back in the line, time to see the change and prepare for it.
-
8. A minor drop has left the clutch lever bent, although it still works. What should be done?
Show answer
Answer B: Have the lever replaced before the motorcycle is ridden again
A bent lever has already been weakened and can break off in use, leaving the rider without that control at the worst possible moment.
-
9. Which item does most to keep a rider comfortable in cold weather beyond a jacket and gloves?
Show answer
Answer B: A close fitting neck cover that stops air entering at the collar
Cold air funnelled in at the neck chills the whole body, so a snug neck tube or balaclava makes a large difference, while a loose scarf is a hazard because it can catch.
-
10. What does a windshield on a motorcycle genuinely provide?
Show answer
Answer B: Relief from wind pressure, rain and cold, which reduces fatigue
A windshield cuts wind blast, weather and fatigue, but air and debris still come around it, so the rider still needs eye protection and full gear.
-
11. A city transit bus at a stop ahead of you switches on its left signal. What should you do?
Show answer
Answer D: Slow and let the bus pull back into traffic
A bus needs a long gap to rejoin traffic, and yielding to a signaling transit bus keeps the whole line of traffic moving safely.
-
12. Some crosswalks are marked with two transverse lines and others with a row of wide bars laid along the direction of travel. Why is the second pattern used?
Show answer
Answer B: It is far easier for an approaching driver to see
Longitudinal bar patterns are used where extra visibility is wanted, such as an uncontrolled crossing or one near a school, because they show up much better from a car.
-
13. What should you do as you approach your exit from a roundabout?
Show answer
Answer A: Signal right and check the crosswalk for pedestrians before leaving
A right signal tells following drivers and waiting drivers that you are leaving, and pedestrians cross at the exit leg, so the crosswalk must be checked.
-
14. You need to leave the road and pull onto the shoulder. What should you check first?
Show answer
Answer A: Whether the shoulder surface is firm enough to support the motorcycle
Soft or loose shoulder material can grab the wheels or let the side stand sink, so confirm the surface is firm, signal, and then pull well clear of traffic.
-
15. About how far ahead do low beam headlights let you see on a dark road?
Show answer
Answer B: About 250 feet
Low beams light roughly 250 feet of road, and high beams roughly 350 to 500 feet, which sets the limit on a safe night speed.
-
16. You notice a bulge on the sidewall of one of your tires. What should you do?
Show answer
Answer D: Have the tire replaced before driving far, because it could blow out
A sidewall bulge means the internal cords have broken and only the rubber is holding the air. The tire can fail suddenly at any speed.
-
17. What does a blood alcohol concentration of 0.08 mean for the driver of a car?
Show answer
Answer B: It is the level almost every state treats as legally intoxicated
In almost every state a driver at 0.08 or above is legally intoxicated whatever the driver seems like, but impairment starts well before that level is reached.
-
18. If the rear wheel locks during a straight line stop on a good surface, the rider should:
Show answer
Answer B: Keep it locked until the motorcycle has come to a complete stop
Releasing a locked rear wheel while the motorcycle is out of line can snap it upright violently, so on a straight path the rear brake is held until the motorcycle stops.
-
19. Which of these makes you unpredictable to other drivers?
Show answer
Answer B: Changing lanes suddenly without signaling, to save a moment
An unsignalled, sudden lane change gives nobody time to react and is a common cause of sideswipe collisions.
-
20. A regulatory sign posted at the start of a road reads LENGTH LIMIT 30 FEET. What does it control?
Show answer
Answer B: The overall length of vehicle allowed on that road
Some states post a length limit where tight curves or narrow structures lie ahead; it bars vehicles or combinations longer than the figure shown from using that road.
-
21. You are passing a crash on the other side of a divided highway. What should you do?
Show answer
Answer D: Keep your eyes on your own lane and the traffic around you
Staring at a crash scene, often called rubbernecking, causes sudden slowing and secondary collisions. Your attention belongs on the traffic in front of you.
-
22. You are already inside a roundabout when an emergency vehicle approaches with lights and siren. What should you do?
Show answer
Answer B: Continue to your exit, leave the roundabout, then pull over and stop
Stopping inside a roundabout blocks the circulating roadway, so you should exit first and then pull over clear of the intersection.
-
23. You are driving in the left lane at the posted speed limit and a line of vehicles has built up behind you. What should you do?
Show answer
Answer D: Move into a lane on your right when it is safe and let the traffic behind go by
Most states require traffic moving slower than the flow to keep right and reserve the left lane for passing, so a driver holding up a line of vehicles should move right when it is safe rather than block the lane.
-
24. After the leader of a staggered group completes a pass, what should the leader do?
Show answer
Answer A: Move to the left position and hold passing speed to open room for the next rider
Returning to the left position and keeping speed opens the gap the next rider needs to finish the pass and settle back into formation.
-
25. What is the main risk of buying a second hand helmet?
Show answer
Answer B: You cannot know whether it has been dropped or crashed already
A helmet's protection depends on a liner that may already be crushed by an impact you cannot see, and a stranger's helmet comes with no history you can trust.
