1. You see brake lights several vehicles ahead of you in your lane. What is the best first step?
Show answer
Answer C: Ease off the gas and cover the brake pedal
Reacting to the trouble several vehicles ahead, rather than waiting for the car in front, cuts your reaction time and warns the driver behind you.
-
2. You have a steady green ball to turn left, and the oncoming traffic gets a green left arrow. What does that mean for you?
Show answer
Answer C: Oncoming vehicles will turn across your path, so you must wait
A green ball is permissive, so when the oncoming side receives a protected arrow those vehicles have priority and you must yield until they clear.
-
3. Your light turns green, but a vehicle is still in the middle of the intersection. What should you do?
Show answer
Answer D: Wait until the intersection is clear before you move ahead
A green light means go only when the way is clear. Drivers already inside the intersection must be allowed to finish crossing.
-
4. Rain is heavy enough that you have your windshield wipers running. What else should you switch on?
Show answer
Answer A: Your headlights, so you can see and others can see you
Rain heavy enough to need wipers also cuts how far away you can be seen, so the headlights belong on. Many states write this into law as a wipers on, lights on rule.
-
5. You make eye contact with a driver waiting to pull out of a side street. What should you assume?
Show answer
Answer D: The driver may still not have seen you, so stay ready to slow or stop
Drivers can look directly at you and still not register your vehicle, especially a small one. Eye contact helps, but never rely on it.
-
6. On a long drive you notice repeated yawning, missed exits and drifting toward the lane line. What should you do?
Show answer
Answer C: Pull off at a safe place and sleep, or change drivers
Those are warning signs that sleepiness is already interfering with driving, and only rest restores alertness. Fresh air, music and caffeine do not reverse it.
-
7. How may a two-way left-turn lane never be used?
Show answer
Answer B: As a through travel lane or a passing lane
The lane exists only for turning movements, so traveling or passing along it puts you head-on with vehicles turning from the opposite direction.
-
8. May you stop in the striped triangle that separates an exit ramp from the freeway lanes?
Show answer
Answer A: No, it is not a lane and stopping there is dangerous
The striped gore area is not a travel lane or a shoulder, and a vehicle stopped there sits directly in the path of drivers correcting a late exit.
-
9. A yellow lamp flashes above a warning sign at a sharp curve. What does it ask of a driver?
Show answer
Answer D: Slow down and pass the point with extra care
A warning beacon draws attention to the sign it is mounted with, and the message of the sign is what the driver must act on.
-
10. You have just passed a vehicle on a two-lane road. When may you return to your lane?
Show answer
Answer B: When you can see the whole vehicle in your inside mirror
Seeing the entire vehicle you passed in your rearview mirror shows there is room to pull back in without cutting it off.
-
11. How does Missouri law treat the number shown on a speed limit sign when a speeding charge is enforced?
Show answer
Answer A: It is presumed to be the legal limit unless rebutted
Missouri law creates a rebuttable presumption that the posted speed limit is the legal speed limit for enforcement purposes.
-
12. Why are pedestrians and cyclists a special risk on unlit streets at night?
Show answer
Answer A: Dark clothing can make them invisible until they are very close
A person in dark clothing reflects almost no light and may not appear until they are inside your stopping distance, so cut your speed where people may be about.
-
13. You are first in the queue at a red light with a marked crosswalk. Where should your vehicle stop?
Show answer
Answer A: Behind the stop line, so that the crosswalk stays clear
Stopping short of the line keeps the crosswalk usable for people on foot and keeps your vehicle out of the path of turning traffic.
-
14. At a stop sign with a painted stop line and a crosswalk, where must you stop?
Show answer
Answer D: At the stop line, before it and before the crosswalk
You stop at the stop line first, and only if there is no stop line do you stop before the crosswalk, and only if there is neither do you stop before entering the intersection.
-
15. What is the maximum fine for a second Missouri hands-free violation within 24 months of the first?
Show answer
Answer D: $250
A second violation within 24 months carries a fine of up to $250 under Missouri's hands-free law.
-
16. 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.
-
17. A rectangular red sign with the white words WRONG WAY means that
Show answer
Answer C: the driver is already traveling against the legal flow and must not continue
The wrong way sign uses a white legend and border on red and addresses a driver who has entered a ramp or one-way roadway in the wrong direction, who should stop and turn around safely.
-
18. A funeral procession with headlights on is crossing an intersection when your light turns green. What should you do?
Show answer
Answer A: Wait and let the whole procession go through
Most states let a funeral procession stay together once the lead vehicle has lawfully entered an intersection, and in every state you must yield to vehicles already in the intersection, so wait until the line has passed.
-
19. Cannabis is legal for adults in some states. What does that mean for driving?
Show answer
Answer C: Driving while impaired by it is still an offense
Legal possession has nothing to do with driving law, and every state treats driving while impaired by cannabis as an offense.
-
20. A driver stopped at a red signal wants to turn right and this sign is posted at the corner. What is permitted?
Show answer
Answer A: Nothing: the turn is barred whether the signal is red or green
The restriction works independently of the signal, so the usual permission to turn right after stopping at a red light does not exist where this sign is posted.
-
21. You are turning left from a one-way street onto a two-way street. How should the turn be made?
Show answer
Answer B: Start in the far left lane and finish just to the right of the center line
Left turns begin from the lane nearest the left edge of the street you are leaving and must finish on the right-hand side of the center line of a two-way street.
-
22. Why should your thumbs rest along the rim rather than hook inside the spokes?
Show answer
Answer D: A jolt can spin the wheel and injure hooked thumbs
A pothole or a dropped wheel can snap the wheel round violently, and thumbs hooked through the spokes are trapped when it happens.
-
23. Travelling at about 55 mph on dry pavement, roughly how much room does an average car need to perceive, react and stop?
Show answer
Answer D: About 300 feet, close to the length of a football field
Reaction distance plus braking distance at 55 mph comes to roughly 300 feet on good dry pavement, and considerably more on a wet or loose surface.
-
24. You hold steady pressure on the brake pedal for the whole of a long descent. What is likely to happen?
Show answer
Answer B: The brakes overheat and fade, so they slow you less and less
Continuous braking heats the brakes until they fade and lose effectiveness; use a lower gear and short, firm applications instead.
-
25. May you park at the curb immediately next to a railroad crossing?
Show answer
Answer A: No, you must leave the crossing and its approach clear
Parking beside a crossing hides the tracks and the signals from approaching drivers and leaves no room for a vehicle that has to clear the rails.
