1. You are approaching a narrow bridge where the road has one lane in each direction and no shoulder. What should you do about passing?
Show answer
Answer B: Do not pass on or near the bridge
A narrow bridge gives neither vehicle anywhere to go, so passing is prohibited there in the same way as on a hill or in a tunnel.
-
2. The car ahead drifts across the lane line and back again several times. What should you do?
Show answer
Answer C: Assume that the driver is distracted or impaired, and keep well back
Drifting is a classic sign of a distracted, drowsy or impaired driver, and distance is your protection from all three.
-
3. You are in the open lane where another lane is merging into yours. What is your part in the merge?
Show answer
Answer A: Keep a steady speed and leave a gap for one vehicle to come in
A merge works when each driver in the through lane lets one vehicle in, which keeps both lines moving instead of stopping them both.
-
4. What does a Missouri driver need to end a first suspension for failing to keep insurance?
Show answer
Answer A: A $20 fee and proof of insurance filed for three years
A first Missouri insurance suspension ends with a $20 fee and an SR-22 filing kept on file for three years.
-
5. What does a steady yellow traffic light tell the driver facing it?
Show answer
Answer A: The green movement is ending and a red indication is about to appear
A steady yellow warns that the related green movement is being terminated and that red will follow, so you should stop if you can do so safely.
-
6. You approach a one-lane bridge and there is a yield sign facing your side of it. What does that mean?
Show answer
Answer B: Oncoming traffic crosses the bridge first and you wait at the approach
At a one-lane bridge the yield sign tells one direction to give way, so you wait clear of the bridge until oncoming traffic has crossed.
-
7. A school crossing guard steps into the roadway and holds up a stop paddle. What must you do?
Show answer
Answer D: Stop and stay stopped until the guard and the children have left the road
A crossing guard directs traffic with legal authority; you must remain stopped until both the guard and the children are clear of the roadway.
-
8. You are entering a marked work zone. What should you expect?
Show answer
Answer B: A reduced posted speed, narrowed or shifted lanes, and traffic that may stop suddenly
Work zones change the geometry of the road and can bring traffic to a halt without warning, so the posted work zone speed and increased following distance both apply.
-
9. Why is texting considered one of the most dangerous distractions?
Show answer
Answer B: It combines visual, manual and cognitive distraction at the same time
Reading or writing a message takes your eyes off the road, at least one hand off the controls and your attention off driving simultaneously.
-
10. An overhead lane signal shows a flashing yellow X above your lane. What does it mean?
Show answer
Answer D: The lane may be used only for a left turn
A flashing yellow X marks a lane that may be used only to make a left turn; a steady yellow X is the one that warns you to leave the lane.
-
11. What is the safest way to deal with a vehicle sitting in your blind spot?
Show answer
Answer A: Slow a little or move ahead so that it is no longer beside you
You cannot control the other driver, but you can change your own speed so that the vehicle is no longer hidden beside you.
-
12. You have entered a work zone where crews are working close to the open lane. What should you do?
Show answer
Answer A: Slow down and be ready for workers and machines
Workers and equipment cross the open lane without warning in a work zone, so reduced speed and attention on the road ahead are what keep them safe.
-
13. A bicyclist stops at a four-way stop just before you do. Who goes first?
Show answer
Answer B: The bicyclist, who reached the intersection and stopped there before you did
A bicyclist on the roadway follows the same right of way rules as a driver, so arrival order decides the turn.
-
14. Which Missouri vehicles are exempt from the biennial safety inspection?
Show answer
Answer B: Those under ten years old with fewer than 150,000 miles
Missouri exempts a vehicle from the safety inspection for the first ten years following its model year, provided the odometer stays below 150,000 miles.
-
15. Which headlight setting should you use in dense fog?
Show answer
Answer B: Low beams
High beams reflect off the water droplets in fog and bounce glare back at you, while low beams aim downward and light the road without that mirror effect.
-
16. A pedestrian signal changes to a flashing upraised hand. What does that indication mean?
Show answer
Answer C: Do not start crossing, but finish a crossing already begun
The flashing upraised hand is the pedestrian change interval: nobody may start to cross, but a pedestrian already in the crosswalk may continue to the far side or to a median.
-
17. What is the best way to handle the radio, the music player and the climate controls on a trip?
Show answer
Answer B: Set them before you start driving and let a passenger handle changes
Fiddling with controls takes eyes and hands off the driving task. Setting them before you move and letting a passenger make later changes removes the distraction entirely.
-
18. Two left-turn lanes are available and you must turn right again a short distance after the turn. Which of the two should you use?
Show answer
Answer D: The right one, so you finish nearer the right side of the new street
Each turn lane feeds the matching lane of the new street, so choosing the right-hand of the two left-turn lanes leaves you closer to the side you will need.
-
19. You have stopped at a stop sign, but a parked truck blocks your view along the cross street. What should you do?
Show answer
Answer A: Creep forward slowly and stop again where you can see
When something blocks the view, a second stop closer to the intersection is the only safe way to see, and it must come before your vehicle enters the traffic lane.
-
20. In the code that governs pavement markings, what does a double line stand for?
Show answer
Answer B: A maximum restriction
The marking code is consistent: a double line means the strongest restriction, a solid line discourages or forbids crossing, and a broken line is permissive.
-
21. What happens to a Missouri driving privilege on conviction for failing to have a required ignition interlock installed?
Show answer
Answer D: It is revoked for one year, and for five on a second offense
A conviction for failing to install a required interlock revokes the Missouri driving privilege for one year, and a second offense costs five years.
-
22. How does a full load of passengers and luggage affect your braking?
Show answer
Answer B: It lengthens the stopping distance, so you should brake earlier
More weight means more energy to get rid of, so a loaded vehicle takes longer to stop and needs earlier, gentler braking.
-
23. A wasp flies in through the open window while you are driving. What is the safest reaction?
Show answer
Answer B: Stay calm, slow down and stop somewhere safe
Far more crashes come from the driver's reaction to an insect than from the insect, so keep your eyes forward, slow down and deal with it stopped.
-
24. How can you check that you are keeping a safe following distance?
Show answer
Answer A: Count at least three seconds between the vehicle ahead passing a fixed object and your reaching it
Pick a fixed roadside object, start counting when the vehicle ahead passes it and make sure at least three seconds elapse before you reach it, adding more time in poor conditions.
-
25. An emergency vehicle is stopped on the shoulder ahead with its lights flashing. What does the move over principle require?
Show answer
Answer D: Change lanes away from it, or slow down if you cannot
Move over laws ask you to give responders an empty lane, and where traffic or a two-lane road makes that impossible, you slow down instead.
