Missouri's permit knowledge test is 25 questions, and you need 20 correct (about 80%) to pass.
Pick an answer on each question to see whether you got it right, with an explanation.
This is a short sample — DriveDrill has 200+ Missouri questions
and full-length mock exams in the app.
Q1. Two lanes merge into one because of road work. The most efficient approach is to:
A Merge a mile early and leave the closing lane empty
B Speed up to get ahead of the merge
C Block the closing lane so nobody uses it
D Use both lanes to the merge point and take turns
The zipper merge keeps queues shorter and speeds more even. Take turns at the merge point rather than fighting over it.
Q2. In Missouri, the law requires a car seat or booster seat until:
A The child turns 8, weighs 80 pounds, or is taller than 4 feet 9 inches
B The child turns 12
C The child turns 16
D The child turns 4
State law is a minimum. Safety experts recommend a booster until the adult belt fits properly: lap belt low across the hips and shoulder belt across the chest, not the neck.
Q3. Your vehicle stalls on railroad tracks and a train is coming. You should:
A Get everyone out and walk away from the tracks at an angle toward the train
B Stay in the vehicle and brace
C Push the vehicle off the tracks
D Try to restart the engine until the last moment
Leave the vehicle immediately and move toward the train at an angle, so flying debris from the impact travels away from you.
Q4. In Missouri, how far before making a turn or lane change should you signal?
A At least 20 feet
B At least 500 feet
C At least 100 feet
D There is no recommended distance
Missouri's guide advises signaling at least 100 feet before you make your move so other drivers can react.
Q5. Counting seconds after the vehicle ahead passes a fixed point is a way to:
A Time how long to signal before turning
B Time how long to wait at a stop sign
C Judge when to switch on headlights
D Judge a safe following distance behind the vehicle ahead
Pick a sign or pole; when the vehicle ahead passes it, start counting. If you reach it before your count is up, drop back. States set the minimum anywhere from two to four seconds in good conditions, and every state says to add time for rain, night and large vehicles.
Q6. After a crash with injury or significant damage you must usually:
A Report it only if you were at fault
B Report it only if a vehicle was towed
C Report it to law enforcement or the state as your state requires
D Report it to your insurer only
Every state sets a damage threshold and a deadline for reporting. Exchange information at the scene and file the report on time.
Q7. In Missouri, a driver under 16 with an instruction permit may be accompanied by someone other than a parent or guardian only if that person is:
A A driving instructor only, with no age requirement
B At least 25 years old, licensed at least three years, with written parental permission
C Any licensed driver over 21
D At least 18 years old with no other requirements
Missouri allows an instruction permit holder under 16 to be accompanied by a person who is at least 25 years old, has been licensed for a minimum of three years, and has received written permission from the parent or legal guardian.
Q8. The only thing that reduces blood alcohol concentration is:
A Coffee
B Exercise
C A cold shower
D Time
The liver processes alcohol at a fixed rate. Nothing speeds it up, so the only plan that works is not driving.
Q9. Under Missouri law, which vehicle occupants are required to wear a seat belt?
A Only rear seat passengers
B Only the driver
C No one; seat belts are optional for adults
D The driver and front seat occupants (all passengers if the driver holds an intermediate license)
Missouri law requires the operator and front seat occupants to wear a seat belt, and all passengers must be restrained when the driver holds an intermediate license.
Q10. A motorcycle is entitled to:
A The shoulder only
B The left lane only
C Half a lane so a car can share it
D The full width of a traffic lane
Never share a lane with a motorcycle. Riders move within the lane to avoid road hazards and to stay visible.
