Question 1 of 30
1. A horizontal black sign with a white arrow and the words ONE WAY points to the left at an intersection. What does it tell you?
Show answer & explanation
Correct answer: C. A ONE WAY sign means every vehicle on that street must travel in the arrow's direction. Driving against it puts you head-on into traffic. Before turning onto any city street, glance for the arrow and follow where it points.
2. A signal shows a flashing yellow arrow for a left turn. What does that allow?
Show answer & explanation
Correct answer: A. A flashing yellow arrow is a yield-and-turn: you may go left after judging gaps, because oncoming traffic still has a green. It is not a protected arrow. Flash yellow means you choose the gap; solid green arrow means the gap is held for you.
3. A pedestrian has stepped into a marked crosswalk on your street, and the light is green for you. What must you do?
Show answer & explanation
Correct answer: B. Pedestrians in a crosswalk have the right-of-way even when your light is green. Stop or slow until they are clear. A green light does not let you run someone over. People in the stripes go first.
4. A yellow diamond sign shows a truck tilted nose-down on a black slope. You are about to descend a long, steep grade. What is the proper technique?
Show answer & explanation
Correct answer: C. On a steep downgrade, shift to a lower gear before descending so engine braking holds your speed, and use the brakes sparingly. Constant braking overheats the pads until they fade and fail. Gears save brakes; brakes alone can quit.
5. You see a five-sided sign shaped like a schoolhouse outline, in fluorescent yellow-green, showing two walking figures. What does the pentagon shape identify?
Show answer & explanation
Correct answer: D. The pentagon shape is reserved for school signs, warning of a school zone or crossing where children may be walking. The fluorescent yellow-green color grabs attention near schools. Think of the five-sided shape as a little schoolhouse to remember it.
6. May you drive unsupervised on a learner’s permit, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA GDL guidance says A learner’s permit allows driving only while supervised by a fully licensed driver. GDL reduces the amount of unsupervised driving by 16-year-olds. The leftover empty-road exception is not on that page.
7. Your 20-year-old cousin is the designated driver tonight in Missouri. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In Missouri, drivers under 21 violate the zero-tolerance law once their BAC reaches 0.02%. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
8. You have signaled and checked your mirrors before a lane change. What is the one step left before you move over?
Show answer & explanation
Correct answer: C. Mirrors leave blind spots big enough to hide a whole car, so turn your head for a quick over-the-shoulder check before moving over. Signal, mirrors, head check: the lane change is not done until your neck moves.
9. What does the term "no-zone" mean when you drive near a large truck?
Show answer & explanation
Correct answer: C. No-zones are the huge blind spots in front of, behind, and beside a large truck where the driver simply cannot see you. A quick test: if you cannot see the driver's face in the truck's mirror, you are invisible.
10. A school-zone sign is posted 25 mph, and children are on the sidewalk. The next block is posted 35. When may you return to 35?
Show answer & explanation
Correct answer: B. School-zone speeds apply through the marked zone while children are present or the lights flash, depending on the sign. Do not jump back to the higher limit at the building line. Wait for the zone to end.
11. You turn off a busy road into a quiet subdivision in Missouri and see no speed limit sign on the new street. Your maximum legal speed is now which value?
Show answer & explanation
Correct answer: D. Once you enter an unposted residential street in Missouri, the limit drops to the default of 25 mph. Slow down as you turn in; the quiet look of a subdivision hides driveways, cyclists, and children near the pavement.
12. The posted limit is unchanged, but traffic, weather, and light have all gotten worse. What does the basic speed rule require?
Show answer & explanation
Correct answer: C. The basic speed rule says you may not drive faster than conditions safely allow, no matter what the sign posts. Rain, darkness, and crowds shrink your margin for error. Conditions set the real limit; the sign sets the ceiling.
13. You have been driving through a no-passing zone. Which sign tells you the zone has ended and passing is allowed again when safe?
Show answer & explanation
Correct answer: D. A white regulatory sign reading PASS WITH CARE marks the end of a no-passing zone. You may pass again, but only when the road ahead is clear. The word CARE reminds you the choice is still yours to judge.
14. You plan to leave the freeway at exit 12. How will you know which ramp is yours?
Show answer & explanation
Correct answer: B. Freeway exits carry green guide signs topped with a numbered exit panel, and the number usually matches the nearest milepost. Match the posted number to your planned exit, then move into the exit lane early.
15. Signs on Missouri highways vary from road to road, but the law sets one absolute top limit for the fastest routes. That limit is which value?
Show answer & explanation
Correct answer: D. By statute, 70 mph is the fastest any Missouri road can be posted. Below that ceiling, engineers set each road's limit for its design and traffic, which is why the posted sign on your road governs.
16. A school bus on a two-lane road has stopped with red lights flashing and the stop arm out. You are coming the other way. What do you do?
Show answer & explanation
Correct answer: B. On an undivided road, both directions stop for a loading school bus. Children can run from either side. The only common exception is the far side of a divided highway with a real median. Red lights plus arm equals freeze.
17. In Missouri, supervised behind-the-wheel practice with a permit can begin once a teen reaches which age?
Show answer & explanation
Correct answer: C. Supervised practice starts at 15 in Missouri, once the teen holds a learner's permit. Every practice hour with a licensed adult builds judgment that classroom study alone cannot teach, which is why the permit stage exists.
18. When should you avoid a U-turn in Missouri?
Show answer & explanation
Correct answer: A. Missouri says you should only make a U-turn when it is safe. U-turns should not be made on any curve or near the crest of a hill, where you cannot see oncoming traffic soon enough. A sign that forbids the U-turn ends the discussion.
19. If it becomes hard to control the car, what does Ready.gov tell you to do?
Show answer & explanation
Correct answer: A. Official Ready.gov car-safety guidance says If it becomes hard to control the car, pull over, stop the car and set the parking brake. The leftover pump-the-failed-brake list is not on that page; this nearby official loss-of-control sentence is.
20. You are parking near railroad tracks. What distance do most state manuals require from the nearest rail?
Show answer & explanation
Correct answer: C. Fifty feet from the nearest rail is the usual keep-clear distance so trains and crossing gates have room and drivers can see. Do not park on or immediately beside the tracks. Fifty for rails, thirty for signs, twenty for walks, fifteen for hydrants.
21. If a state legalizes marijuana possession, may you drive under the influence of the drug?
Show answer & explanation
Correct answer: A. Official NHTSA drug-impaired-driving guidance says Even in states where marijuana laws have changed, it is still illegal to drive under the influence of the drug. Driving impaired by any substance is against the law in all 50 states and the District of Columbia.
22. Two cars arrive at a four-way stop at the same time, facing each other, and the car across from you is going straight. You want to turn left. Who should go first?
Show answer & explanation
Correct answer: B. At a four-way stop, through traffic goes before a facing left turn when you arrive together. The left-turner would otherwise cut across the straight path. Straight first, then the left — same idea as an unprotected green.
23. A friend says every US interstate is 80 mph. In Missouri, the highest posted highway limit is actually:
Show answer & explanation
Correct answer: A. Interstate limits vary. Missouri tops out at 70 mph where posted. Learn the number for your state, then obey the sign in front of you, which is often lower.
24. Your younger sibling asks when they can get a learner's permit in Missouri. What age do you tell them?
Show answer & explanation
Correct answer: A. Tell them 15; that is when Missouri allows a learner's permit application. Until then, driving on public roads is off the table. Graduated licensing phases in privileges so new drivers gain experience under lower-risk conditions.
25. Which fee listing matches what the DOR currently publishes for a Missouri permit or license application?
Show answer & explanation
Correct answer: A. The DOR lists this Missouri amount: Class F instruction permit (minimum age 15): $10, duplicate $10. Intermediate license (Class F): $14. Written and road test fees are not included in the DOR fee chart, and card payments add a 2.0% + $0.25 vendor charge.. Fees change, and extras like photos or late replacements can stack. Confirm the number on the official fee page the day you go, and bring an accepted payment type.
26. Missouri traffic signals are dark or not working. How should you treat the intersection?
Show answer & explanation
Correct answer: A. Missouri says dark signals, or traffic signals that are not working, operate as a four-way stop. Every approach stops, then goes in turn when it is safe. Do not assume the main street still has a free green.
27. A Missouri traffic officer is giving directions that conflict with a green light. What must you do?
Show answer & explanation
Correct answer: A. Missouri says you must obey traffic officers at all times. If an officer signals you to stop at a green light, you stop. Resume the signal only after the officer releases the intersection.
28. You are 25 and had wine at a dinner party in Missouri. Before driving home, you check the law. At what BAC does driving become illegal for you?
Show answer & explanation
Correct answer: D. For adult drivers in Missouri, driving is illegal at a BAC of 0.08% or above. Because impairment starts before the limit, the safest plan after drinking is a ride share, taxi, or sober designated driver.
29. It is late at night and the unposted residential streets in your Missouri neighborhood are empty. The legal maximum for these streets remains which speed?
Show answer & explanation
Correct answer: C. Empty or busy, day or night, the default limit on unposted residential streets in Missouri stays 25 mph. Darkness actually cuts how far you can see and react, so conditions may call for less, not more, than the limit.
30. You are parking facing uphill on a street with a curb. Which way should you turn your front wheels?
Show answer & explanation
Correct answer: B. When parking uphill with a curb, turn the wheels away from the curb and let the car roll back until a tire rests against it. The curb then works as a block. Up and away is the memory cue.
