1. A center lane is bordered by a solid yellow line on the outside and a broken yellow line on the inside, with left-turn arrows painted in it. How may you use that lane?
Show answer
Answer A: Only to make a left turn or to prepare for one from either direction
That marking identifies a two-way left turn lane, which may only be used for left turns or to prepare for a left turn and never for travel or passing.
-
2. You are traveling beside a tractor-trailer and cannot see the truck driver's face in any of the truck's mirrors. What does that tell you?
Show answer
Answer A: The truck driver probably cannot see your vehicle
Large trucks have deep blind spots on all four sides, so if the driver's face is not visible in a mirror the driver has no view of you. Move ahead or drop back until you are out of that area.
-
3. How much following distance should you keep behind a motorcycle?
Show answer
Answer C: At least three to four seconds
A motorcycle can slow or stop very quickly and is easily upset by a surprise, so allow three to four seconds instead of the usual car gap.
-
4. What does it mean to scan the road while driving?
Show answer
Answer A: Moving your eyes constantly over the road, the sides and the mirrors
Scanning keeps information coming in from every direction, while a fixed stare leaves you blind to everything else.
-
5. A shared-use path crosses the road ahead at a marked crossing and people are already crossing on it. What should you do?
Show answer
Answer C: Yield and let them finish crossing the road
People already crossing at a marked crossing have the right of way, and a path crossing is a crossing of the roadway like any other.
-
6. At what age does Missouri allow a driver to move from an intermediate license to a full Class F driver license?
Show answer
Answer C: 18 years old
Step Three of the Missouri Graduated Driver License program, the full under-21 driver license, has an eligible age of 18.
-
7. You are stopped at a stop sign on a two-way stop intersection and the cross street has no stop signs at all. What does that mean for you?
Show answer
Answer A: You yield to all cross traffic no matter how long that takes
At a two-way stop only your direction is controlled, so there is no taking turns; you wait for a gap big enough to enter safely.
-
8. What is the correct order of a pass on a two-lane road?
Show answer
Answer A: Check ahead and behind, signal left, move out, accelerate past, signal right and return
A pass begins with the decision that the road is clear and ends with a signaled return, and each step warns other drivers before the vehicle moves.
-
9. At the scene of a crash you were part of, what are you required to do besides stopping?
Show answer
Answer B: Give your name, your address and vehicle details, and help anyone who is hurt
Every state requires drivers involved in a crash to identify themselves and to render reasonable aid to anyone injured.
-
10. The green arrow protecting your turn changes to a steady yellow arrow. What is it telling you?
Show answer
Answer A: The protected turn is ending and you should prepare to stop
A steady yellow arrow warns that the arrow movement is being terminated and that a red indication will follow.
-
11. On which approach is this sign normally installed?
Show answer
Answer C: On the road that ends, far enough ahead for the driver to slow down
The warning belongs on the approach that terminates, placed early enough that the driver can lose speed and choose a direction before reaching the junction.
-
12. How does going a long time without sleep compare with drinking?
Show answer
Answer A: It can impair a driver in much the same way
Long periods awake produce slow reactions, poor judgment and lapses of attention that resemble the effects of alcohol, which is why fatigue counts as impairment.
-
13. A pedestrian signal displays a steady walking person symbol. What does it mean for a pedestrian at that corner?
Show answer
Answer B: The pedestrian may start crossing in the direction of the signal
The steady walking person permits a pedestrian to begin the crossing, while still yielding to vehicles already lawfully in the intersection.
-
14. How many points does Missouri assess for leaving the scene of a crash under state law?
Show answer
Answer C: 12 points
Leaving the scene of a motor vehicle crash carries 12 points under Missouri state law, while the same offense under a municipal ordinance carries six.
-
15. Your exit from a three-lane highway is about a mile ahead on the right, and you are in the left lane. What should you do?
Show answer
Answer B: Start moving right now, one lane at a time
Plan ahead and change lanes one at a time well before the exit, so you never have to cut across several lanes at the gore.
-
16. You are entering an angle parking space on your right. What should you do?
Show answer
Answer C: Stay a little left of the space, then turn in between the lines
Keeping a little left of the space gives the front wheels the room to turn in cleanly and leaves your car centered between the lines.
-
17. You are waiting inside the intersection to turn left when your light turns red. What should you do?
Show answer
Answer A: Complete the turn as soon as the way is clear
Once you have legally entered the intersection you should clear it as soon as the oncoming traffic has stopped, rather than sit in the path of cross traffic.
-
18. Smoke and flames appear from the engine compartment after you stop. What should you do?
Show answer
Answer A: Get everyone well away from the vehicle first, and then call the fire service
A vehicle fire can spread within seconds, so people come out first and firefighting is left to the fire service.
-
19. 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.
-
20. Why is hard braking the wrong response to a tire blowout at speed?
Show answer
Answer C: Because it can pull the vehicle further out of line and start it spinning
With one tire gone the braking forces are uneven, so heavy braking increases the pull to one side and can spin the vehicle.
-
21. Your phone is in a mount on the dashboard rather than in your hand. What is true?
Show answer
Answer B: It still takes your eyes and mind off the road
A mount solves the hand problem but not the eye or the mind problem, and reading or tapping a mounted screen costs the same seconds of attention.
-
22. A yellow diamond showing the silhouette of a deer warns that
Show answer
Answer D: large animals may cross the road in that area
The sign marks a stretch where animals are known to cross, so drivers should reduce speed and scan both roadsides, especially around dawn and dusk.
-
23. This sign leads to a crossing that has no gates and no flashing lights. What does that mean for the driver?
Show answer
Answer D: Nothing will warn of an approaching train, so the driver must check the tracks personally
At a passive crossing there is no active device to announce a train, so the whole judgment rests on the driver, who must approach slowly enough to stop after looking along the track.
-
24. A high truck ahead of you hides the traffic signal as you approach the intersection. What should you do?
Show answer
Answer A: Drop back so you can see the signal and the truck's brake lights
Extra following distance restores your view of the signal, so you are reacting to the light yourself rather than copying the truck driver.
-
25. The overhead signal above your lane changes to a steady yellow X. What should you do?
Show answer
Answer B: Prepare to move out of that lane
A steady yellow X warns that the lane is about to close, so drivers should get ready to vacate it in favor of an open lane.
