2. When is a child ready to use a vehicle seat belt without a booster seat?
Show answer
Answer A: When the lap belt lies across the upper thighs and the shoulder belt crosses the chest
Belt fit, not age, decides readiness. Until the child is tall enough for the lap belt to sit on the thighs and the shoulder belt on the chest, a booster is needed.

3. A truck passes you in heavy rain and its spray blanks out your windshield. What should you do?
Show answer
Answer B: Hold the wheel steady, ease off slightly and let the wipers clear it
The blackout lasts a second or two. Keeping your line and easing off is far safer than braking hard or steering blind toward the shoulder.
-
4. Why should you not rest your foot on the brake pedal as you drive?
Show answer
Answer D: The brake lights stay on and the drivers behind cannot read you
Resting on the pedal keeps the brake lights lit and wears the brakes, so following drivers stop believing your brake lights.
-
5. The lights at a highway-rail grade crossing begin to flash red as you approach. What must you do?
Show answer
Answer B: Stop short of the tracks and wait until the lights stop and no train is near
Flashing red lights at a crossing require a stop clear of the tracks, and you may proceed only once the lights have stopped, any gates are fully raised and no train is approaching.
-
6. You park facing downhill on a one-way street where the curb is on your left. Which way do the front wheels go?
Show answer
Answer A: Left, toward the curb on that side
Standard practice follows the curb rather than the side of the road: facing downhill the wheels point into the curb so a rolling vehicle is stopped by it. States differ on whether this is legally required.
-
7. A sign at the signal reads LEFT TURN ON GREEN ARROW ONLY. The ball turns green but no arrow appears. What may you do?
Show answer
Answer C: Wait, because your turn is allowed only while the arrow is showing
The sign removes the permissive turn, so the left is legal only during the green arrow and you must wait behind the line until it appears.
-
8. You are waiting to turn left and an oncoming vehicle stopped in the near lane to turn left blocks your view of the far lane. What should you do?
Show answer
Answer A: Wait where you are until you can see that the far lane is completely clear
The lane you cannot see is where the crash comes from, so you hold your position until the view opens up.
-
9. Your light turns green while a pedestrian who started on the walk signal is still crossing in front of you. What must you do?
Show answer
Answer D: Let them finish crossing the road before you move off on your green light
A pedestrian who entered the crosswalk lawfully keeps the right of way until they reach the other side, whatever the signal now shows.
-
10. Why is a U-turn on a one-way street a problem?
Show answer
Answer A: You would end up facing the wrong way against all the traffic
Every lane of a one-way street runs the same way, so turning around leaves you driving head-on against all of the traffic.
-
11. A notification appears on your smart watch while you are driving. What should you do?
Show answer
Answer B: Treat it as you would a phone and leave it
A watch screen demands the same eyes and the same attention as a phone, and a wrist is no safer a place to read a message than a dashboard.
-
12. You stop at a rest area because you are sleepy. How long a nap is usually recommended?
Show answer
Answer D: About fifteen to twenty minutes
A short nap of fifteen to twenty minutes restores useful alertness without leaving the grogginess a longer sleep can bring, and you should wait a few minutes before driving on.
-
13. A driver moves into the space you were keeping ahead of you. What should you do?
Show answer
Answer D: Ease off and rebuild the gap in front of you
Losing a following gap is common in traffic; the answer is simply to drop back and recreate it rather than drive too close.
-
14. Two vehicles meet on a steep, narrow mountain road with no room to pass. Which driver should back up?
Show answer
Answer C: The driver heading downhill, who has more control while reversing
On a narrow mountain road the vehicle facing downhill yields, because backing uphill gives better control than reversing down a grade.
-
15. What is the function of a regulatory sign?
Show answer
Answer A: To inform road users of traffic laws or regulations that apply at that location
Regulatory signs state requirements that carry the force of law where they are posted, so disregarding one is a violation rather than a lapse of judgment.
-
16. Why is passing another vehicle a bad idea in dense fog?
Show answer
Answer C: You cannot see far enough ahead to know the passing lane is clear
A pass needs a clear view of the road well beyond the vehicle you are overtaking, and fog takes exactly that away.
-
17. A driver reaching a stop sign is required to do what?
Show answer
Answer D: Come to a complete stop and then proceed only when it is safe
A stop sign requires a full stop before the stop line, crosswalk or intersection, after which the driver may go on once the way is clear.
-
18. You are waiting to turn left at a solid green light with no green arrow. Oncoming traffic is approaching. What should you do?
Show answer
Answer A: Yield to the oncoming traffic and turn only when there is a safe gap
A solid green light permits the left turn but does not protect it, so you must yield to oncoming vehicles and to pedestrians before turning.
-
19. A center lane is marked with a broken yellow line on each side and is controlled by overhead lane signals. How is that lane used?
Show answer
Answer A: It carries traffic one way or the other according to the signals
A reversible lane is marked with broken yellow lines on both sides and its direction of travel is set by the lane control signals above it.
-
20. You have passed a large truck and want to move back into its lane. What should you see first?
Show answer
Answer B: Both of its headlights in your rear-view mirror
Seeing both headlights in your mirror means you are far enough ahead to be out of the truck's front no-zone before you move over.
-
21. You are turning left across tracks that run along the center of the street. What should you do before crossing them?
Show answer
Answer B: Look along the tracks in both directions and cross only when clear
Rail vehicles running in the street can arrive from either direction and cannot stop quickly, so look along the tracks before you turn across them.
-
22. A rectangular marker with alternating black and retroreflective yellow stripes set at a slant is used to
Show answer
Answer C: mark an obstruction, with the stripes sloping down toward the side on which traffic should pass
This striped panel is an object marker, and the direction in which the stripes slope shows the driver which side of the obstruction to pass on.
-
23. Who may set a Missouri state highway speed limit above or below the uniform maximum, and what ceiling applies?
Show answer
Answer C: The highways and transportation commission, up to 75 mph
The state highways and transportation commission may raise or lower a limit on the recommendation of the Department of Transportation, but no Missouri speed limit may be set above 75 mph.
-
24. Which of these would appear as a symbol on a blue general service sign?
Show answer
Answer A: A hospital
General service signs cover facilities such as hospitals, fuel, food, lodging, camping, telephones and rest areas, all shown in white on blue.
-
25. You are turning right onto a one-way street. Which lane of that street should you enter?
Show answer
Answer C: The lane closest to the right curb
Even though every lane on a one-way street runs your way, a right turn must end in the lane nearest the right curb; you may change lanes afterwards when it is safe.
