1. Which of the four blind spots around a tractor-trailer is the largest?
Show answer
Answer A: The one on the right side of the truck
A truck has no-zones on all four sides, and the right-side blind spot is the largest because it runs back along the trailer and reaches across more than one lane.
-
2. What should you check on the hitch before towing a trailer?
Show answer
Answer B: That the coupler is locked and the safety chains are crossed underneath
The coupler must be latched and pinned, and the chains crossed under the tongue so they cradle it if the coupling lets go.
-
3. Why does a long downhill grade lengthen the distance you need to stop?
Show answer
Answer C: Because gravity keeps pulling the vehicle forward as you brake
On a downgrade gravity works with the vehicle and against the brakes, so the same speed needs noticeably more distance than it would on level ground.
-
4. What is the eligible age for a Missouri instruction permit, the first step of the Graduated Driver License program?

Answer B: 15 years old
Step One of Missouri's Graduated Driver License program is the instruction permit, for which the eligible age is 15.
-
5. You are waiting to pull out of a driveway when a bicyclist comes along the bike lane in front of you. What must you do?
Show answer
Answer D: Wait until the bicyclist has gone past
A driver leaving a driveway yields to everything already on the road, and a bike lane is part of the roadway.
-
6. Some crosswalks are marked with two transverse lines and others with a row of wide bars laid along the direction of travel. Why is the second pattern used?
Show answer
Answer B: It is far easier for an approaching driver to see
Longitudinal bar patterns are used where extra visibility is wanted, such as an uncontrolled crossing or one near a school, because they show up much better from a car.
-
7. How does Missouri grade a hands-free violation that causes serious physical injury?
Show answer
Answer D: A class B misdemeanor
Causing serious physical injury while violating Missouri's hands-free law is a class B misdemeanor.
-
8. You have loaded the trunk heavily. Why might oncoming drivers flash their lights at you at night?
Show answer
Answer D: The rear sits lower, so your headlights point higher and dazzle them
Weight in the back tips the vehicle nose up and lifts the beam pattern, so low beams shine into the eyes of drivers coming the other way.
-
9. A sign showing a walking figure inside a red circle with a diagonal slash stands at the start of a bridge. What does it mean?
Show answer
Answer C: People on foot may not use that roadway
The no pedestrians sign excludes people on foot from that roadway altogether, which is common on high-speed bridges and freeways.
-
10. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
-
11. What is a marked loading zone for?
Show answer
Answer A: Loading and unloading only, not for general parking
A loading zone is reserved for actively loading or unloading goods or passengers; leaving a vehicle there for other reasons is a parking violation.
-
12. An angry driver is following you closely and gesturing at you. What is the safe response?
Show answer
Answer B: Drive to a police station or to a busy public place and call for help
Never stop to confront an aggressive driver and never lead one home; go somewhere public and get the police involved.
-
13. You are pulling out of a farm entrance onto a rural highway. What is your obligation?
Show answer
Answer C: Yield to every vehicle already on the highway before you enter the roadway
A driver entering a highway from a private road or driveway yields to every vehicle already on the highway.
-
14. You are approaching a refuse collection truck working along your street. What should you expect?
Show answer
Answer D: Workers stepping into the road around the truck
Collection crews move constantly between the truck and the curb, often from where you cannot see them, so slow right down and pass only when the whole area is clear.
-
15. The cars in front of and behind your parallel parked car have left you very little room. How do you get out?
Show answer
Answer D: Ease back and forth, turning the wheels each way, until you clear
Short movements with the wheels turned first one way and then the other walk the car out of a tight space without touching anything.
-
16. Can a driver be charged with impaired driving after taking a legal over the counter medicine?
Show answer
Answer C: Yes, if the medicine impairs the ability to drive safely
Impaired driving laws cover any substance that affects driving, including cold remedies, allergy pills and sleep aids sold without a prescription.
-
17. Why should you make sure your turn signal has stopped flashing after a lane change?
Show answer
Answer A: A signal left flashing tells other drivers that you intend to move again
Other drivers act on your signals, so one that is left on gives them false information about what you are about to do.
-
18. The vehicle you have borrowed is larger and heavier than your own. How should you drive it?
Show answer
Answer B: Allow more room for stopping and for turns until you are used to it
Extra weight and length mean longer stopping distances and wider turns, so give yourself more room until you are used to it.
-
19. Which of these does NOT affect how fast alcohol reaches the bloodstream?
Show answer
Answer A: How confident the drinker feels
Food, the strength of the drinks and the speed of drinking all change how fast alcohol is absorbed, but a drinker's confidence changes nothing at all.
-
20. A warning sign showing two children on a see-saw is posted beside a residential street. What does it mean?
Show answer
Answer D: A play area lies beside the road and children may run out
The playground sign warns that children are present next to the roadway and may enter it without looking, so drivers should cover the brake and slow down.
-
21. Beyond this sign, cones and temporary signs lead traffic along a path that does not agree with the lines painted on the pavement. Which one must the driver follow?
Show answer
Answer C: The temporary arrangement, because it replaces the permanent layout while the work lasts
Temporary traffic control set up for the work takes precedence over the permanent signs and markings, which no longer describe how the road is being used.
-
22. You are turning left out of a driveway onto a busy two-way street. What must you do?
Show answer
Answer D: Wait for a gap in both directions before you start to move
The turn crosses one direction of traffic and joins the other, so you need a gap in both before leaving the driveway rather than stopping across a lane.
-
23. You are traveling beside another vehicle on a multilane highway at nearly the same speed. Why is this a poor position?
Show answer
Answer B: You may be sitting in that driver's blind spot with nowhere to go if they move over
Driving alongside removes your side escape route and often puts you where the other driver cannot see you. Speed up or drop back to open space beside you.
-
24. A driver behind you on a two-lane road clearly wants to pass. Why should you not wave that driver past?
Show answer
Answer B: You cannot see the whole road ahead for them and they may rely on your signal
Waving another driver out invites them to trust your judgment of a road you cannot see well enough, and the decision to pass belongs to the driver making it.
-
25. You reach an intersection showing a steady red light, and a stop line is painted across your lane. Where must you bring the vehicle to a complete stop?
Show answer
Answer C: Before the stop line
A steady red requires a complete stop before the marked stop line. Where there is no stop line you stop before the crosswalk, and where there is neither, before entering the intersection.
