1. What is the purpose of carrying a first aid kit in your vehicle?
Show answer
Answer D: It lets you treat cuts and bleeding while the help is on its way
A kit is for simple first aid such as controlling bleeding until trained help arrives, not a substitute for calling for that help.
-
2. Your passenger has ridden on other people's motorcycles before. What should you do before setting off?
Show answer
Answer A: Brief them anyway, because your machine and your instructions differ
Handholds, footrests, exhaust position and the signals a rider uses all vary from machine to machine, so every passenger is briefed on the machine they are about to ride on.
-
3. You are driving through a long curve on a road with two lanes in your direction. What is correct?
Show answer
Answer A: Stay within your own lane all the way through, adjusting speed before you enter
Wandering out of your lane in a curve puts you into the path of a vehicle you cannot see, and the slowing belongs before the curve rather than in it.
-
4. A large insect splatters on your face shield and blocks part of your view. What should you do?
Show answer
Answer D: Keep control, look through a clear part, and clean it at the next stop
Taking a hand off the bars or riding with your eyes closed is far more dangerous than a partly obscured view, so keep riding and clean the shield when you are stopped.
-
5. You are approaching a traffic light that has been green for a long time. How should you treat it?
Show answer
Answer C: Expect it to change and be ready to stop
A light that has been green for a while is called a stale green light. Cover the brake and decide in advance where you could still stop safely.
-
6. Why does a rider on an unfaired motorcycle tire faster on a long highway ride than a driver would?
Show answer
Answer A: Constant wind pressure and noise drain energy hour after hour
Fighting wind pressure and enduring wind noise for hours is physically tiring, which is why wind protection and regular breaks matter on long rides.
-
7. A driver moves into the space you were keeping ahead of you. What should you do?
Show answer
Answer D: Ease off and rebuild the gap in front of you
Losing a following gap is common in traffic; the answer is simply to drop back and recreate it rather than drive too close.
-
8. The posted limit is 55 mph, but heavy traffic and rain make that speed unsafe. What does the law expect of you?
Show answer
Answer D: You must slow to a speed that is safe for the conditions
The basic speed rule requires a speed that is reasonable for the traffic, weather and road, and that speed is often well below the posted maximum.
-
9. A stop line is painted across the pavement at this sign. Where must the vehicle come to rest?
Show answer
Answer A: Behind the stop line, with no part of the vehicle across it
The vehicle must halt behind the stop line; where no line is painted the driver stops before the crosswalk, and where there is neither, before entering the intersection.
-
10. When must a Missouri driver install an ignition interlock device before reinstatement?
Show answer
Answer B: After a repeat contact, a BAC of .15 or higher, or harm caused
Missouri requires an interlock for at least six months from reinstatement when the driver has more than one intoxication-related contact, a BAC of .15 percent or higher, or caused property damage or bodily harm.
-
11. A pedestrian is crossing a wide four-lane street and has reached the lanes on the far side. When may you go on?
Show answer
Answer C: Only after the person has finished crossing the roadway
Waiting until the pedestrian has finished crossing is correct in every state and removes any doubt about how much clearance your state demands.
-
12. The green left-turn arrow ends and a steady red ball comes on for your lane, at an intersection where no turn on red is allowed. What must you do?
Show answer
Answer D: Stop and wait, because no turn is allowed while the red ball is lit
Once a red indication faces your lane and no turn on red is permitted there, the turn is over; only a vehicle already inside the intersection completes its movement.
-
13. A city transit bus ahead of you has stopped at the curb with its passenger door open. What does the law require of you?
Show answer
Answer D: Nothing special, but pass slowly and watch for people
The mandatory stop applies to a school bus showing red flashing lights, not to a transit bus, though a careful driver still slows for crossing passengers.
-
14. Unless posted otherwise, what is the maximum speed on Missouri rural interstates and freeways?
Show answer
Answer D: 75 mph
Since August 28, 2026, RSMo 304.010 sets 75 mph as the uniform maximum on Missouri rural interstates and freeways, with 65 mph on rural expressways and 60 mph inside urbanized areas; MoDOT may still post lower limits on specific segments.
-
15. The traffic signal is green, but the crossing lights on the tracks inside the intersection begin to flash. What must you do?
Show answer
Answer C: Stop clear of the tracks and wait, even though the signal is green
Active crossing warning devices outrank the green indication, so you stop short of the rails and wait until the warning stops.
-
16. Why do groups agree on a set of hand signals before setting off?
Show answer
Answer B: Because engine noise and helmets make speech useless between moving machines
Riders cannot talk to each other while moving, so agreed signals for hazards, stops, fuel and single file keep the whole group informed.
-
17. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
18. Why should a rider reduce speed at night even on a familiar road?
Show answer
Answer C: So the stopping distance stays inside the distance the headlight lights up
At night you can only react to what the headlight shows, so keep your speed low enough that you can stop within the lit distance ahead.
-
19. You are pulling out of a farm entrance onto a rural highway. What is your obligation?
Show answer
Answer C: Yield to every vehicle already on the highway before you enter the roadway
A driver entering a highway from a private road or driveway yields to every vehicle already on the highway.
-
20. You are stopped at a red light waiting to turn right where the turn is allowed. Besides traffic from the left, what must you check?
Show answer
Answer D: Both crosswalks, and anyone approaching along your right side
A right turn on red crosses the crosswalk in front of you and enters the one on the cross street, and cyclists often approach along your right.
-
21. A driver who is passing you cannot complete the pass because a vehicle is coming. What should you do?
Show answer
Answer C: Ease off the accelerator and make room for them to drop back in
The only place for the passing vehicle to go is the gap behind you, and easing off opens that gap immediately.
-
22. A yield sign is posted where an entrance ramp meets the highway. What must you do?
Show answer
Answer C: Give way to the traffic already on the highway and merge into a gap
The yield sign confirms that the merging driver is the one who must fit into the traffic stream rather than the other way round.
-
23. Why is dusk one of the harder times of day to drive?
Show answer
Answer B: The failing light blurs shapes into the background
In fading light there is not enough contrast to pick objects out, yet it is not dark enough for headlights to do the work, so pedestrians and cyclists disappear.
-
24. The gates at a railroad crossing begin to come down as you approach. What must you do?
Show answer
Answer A: Stop and wait until the gates are fully raised and the lights stop flashing
Once the gates start down you must stop clear of the tracks and wait until they are fully raised and the warning lights have stopped.
-
25. The leader gives a hand signal that you can see clearly from your place in the group. What should you do with it?
Show answer
Answer A: Repeat the signal so the riders behind you also receive it
Signals are passed down the line rider by rider, because riders further back cannot see the leader through the machines in between.
