1. The gates at a railroad crossing are down, and you can see that the road beyond them is clear. What is the correct action?
Show answer
Answer A: Wait until the gates rise completely and the lights go out
Lowered gates mean rail traffic is expected, and driving around them removes the only protection the crossing provides.
-
2. Under Missouri's Abuse and Lose law, how long may a driver under 21 lose the license for an alcohol-related traffic offense?

The Abuse and Lose law allows the license of a driver under 21 to be taken away for 90 days for any intoxication-related traffic offense or for possessing or using alcohol or drugs while driving.
-
3. Where among these is parking specifically prohibited?
Show answer
Answer A: On a bridge, in a tunnel or on railroad tracks
Bridges and tunnels have no safe refuge and cannot be widened, and a vehicle left on railroad tracks cannot be avoided by an approaching train.
-
4. Along a highway the reference markers count upward as you travel. Where does the numbering normally begin?
Show answer
Answer C: At the southern or western edge of the state
Mileage numbering starts where the route enters the state from the south or the west, so rising numbers tell a driver which way they are heading.
-
5. You and an opposing driver reach a four-way stop at the same time and both of you are turning right. What should happen?
Show answer
Answer C: Both may turn at the same time into their own lanes
Two opposing right turns take drivers into different lanes without crossing, so both can proceed together once pedestrians are clear.
-
6. What is the correct order of steps as you finish parking an automatic on a grade?
Show answer
Answer C: Turn the wheels, set the parking brake, then select park
Setting the parking brake before shifting into park lets the brake take the load, instead of leaving the whole weight of the car on the parking pawl.
-
7. A driver reaches this sign and the intersecting roadway is completely clear. What is required?
Show answer
Answer D: Slowing to a speed that allows stopping, then going on without stopping if the way stays clear
This control asks the driver to slow down and be ready to stop, and a full stop becomes necessary only when traffic or pedestrians would otherwise be interfered with.
-
8. You are approaching a multilane roundabout. When should you choose your lane?
Show answer
Answer C: Before you enter, using the lane-choice sign on the approach
You select your lane on the approach the way you would at any multilane intersection, then stay in that lane all the way around, because changing lanes inside a roundabout creates side-impact conflicts.
-
9. Besides 12 points in 12 months, which totals revoke a Missouri driving privilege for one year?

Answer C: 18 points in 24 months or 24 points in 36 months
Missouri revokes a driving privilege for one year at 12 points in 12 months, 18 points in 24 months, or 24 points in 36 months.
-
10. How much of a traffic lane is a motorcycle entitled to use?
Show answer
Answer D: The full width of the lane
A motorcycle is entitled to the full lane, and riders move within it to stay visible and to avoid surface hazards, so drivers should never try to share a lane with one.
-
11. The steering suddenly becomes very heavy while you are driving. What has happened and what should you do?
Show answer
Answer C: The power steering has failed, so steer with more effort and pull over
Loss of power assistance leaves the steering usable but very heavy. Keep both hands on the wheel, slow gradually and pull off the road to check it.
-
12. A regulatory sign posted at the start of a road reads LENGTH LIMIT 30 FEET. What does it control?
Show answer
Answer B: The overall length of vehicle allowed on that road
Some states post a length limit where tight curves or narrow structures lie ahead; it bars vehicles or combinations longer than the figure shown from using that road.
-
13. A blue motorist service sign showing a fuel symbol and an arrow means that
Show answer
Answer D: fuel is available in the direction shown, and the sign imposes no obligation
Service signs are informational: they tell the driver what is available and in which direction, but they create no requirement.
-
14. You are about to leave a roundabout when a pedestrian steps into the crosswalk on your exit. What should you do?
Show answer
Answer B: Yield to the pedestrian and wait for the crosswalk to clear
Roundabout crosswalks sit on the entries and exits, and drivers must yield to pedestrians using them.
-
15. You are turning right from a one-way street onto a two-way street. Where should the turn end?
Show answer
Answer A: In the lane nearest the right curb of the street you are entering
A right turn starts and finishes as close to the right as practical, so you leave the one-way street from the right lane and arrive in the lane nearest the right curb.
-
16. A sign shows a lane joining from the right with no merge required. What does that mean?
Show answer
Answer B: The joining traffic gets its own new lane, so nobody has to merge
An added lane means the roadway gains a lane at that point, so entering vehicles have somewhere to go without anyone changing lanes.
-
17. How does being tired change your total stopping distance?
Show answer
Answer A: It lengthens it, because you take longer to notice and react
Fatigue stretches perception and reaction time, and every extra fraction of a second is added distance before the brakes even begin to work.
-
18. You are approaching a highway-rail grade crossing marked only with a crossbuck sign. What does that sign require?
Show answer
Answer A: Yield to any approaching train and cross only when the tracks are clear
The crossbuck is a regulatory yield sign, and a train can never stop or steer around a vehicle, so the driver must always give way.
-
19. A small yellow plaque showing a speed number below a curve warning sign gives
Show answer
Answer C: the speed recommended for the condition being warned about
The advisory speed plaque belongs to the warning series and states the speed judged safe for the condition ahead under good circumstances, not a regulatory limit.
-
20. At which location is this sign normally installed?
Show answer
Answer D: Facing traffic that could turn into a one-way roadway or ramp against the flow
It is posted where a driver could otherwise enter a ramp or a one-way roadway from the wrong end, so it faces exactly the traffic that has to be kept out.
-
21. A sign showing a walking figure carries a plaque below it with an arrow slanting down to the right. What does the plaque add?
Show answer
Answer B: The crossing is at that very spot
A downward-slanting arrow plaque marks the crossing itself, whereas an AHEAD or distance plaque would place it further along the road.
-
22. How is a Missouri speeding violation classified when the driver exceeds the posted limit by 20 mph or more?
Show answer
Answer C: A class B misdemeanor
Ordinary speeding is a class C misdemeanor in Missouri, but exceeding the posted limit by 20 mph or more raises the offense to a class B misdemeanor.
-
23. A tractor-trailer is backing slowly across the roadway to enter a loading dock. What should you do?
Show answer
Answer C: Stop and wait until the truck has finished the maneuver
A backing truck driver has a very limited view and the trailer can swing unexpectedly. Trying to squeeze past in either direction risks being crushed.
-
24. A crash happens directly in front of you and vehicles are blocking both lanes. What should you do?
Show answer
Answer B: Stop at a safe distance, put on the hazards and warn the traffic behind
The greatest danger after a crash is a second collision, so stop short of it and make sure the traffic behind you can see the problem.
-
25. What counts as a complete stop at a stop sign?
Show answer
Answer C: The wheels stop turning before the stop line
A legal stop means the vehicle is no longer moving, made at the stop line or before entering the crosswalk or intersection.
