Am I Ready for the Missouri Permit Test?
12-question diagnostic · 4 easy, 4 medium, 4 hard · Updated July 12, 2026
Twelve questions, deliberately mixed: four easy, four medium, four of the hardest in our verified Missouri bank. The real test needs 80% — but a diagnostic this short needs a margin, so read your result like this: 11+ of 12, you're ready to book; 9–10, you're close — drill the 25 hardest first; below that, work the full test ladder before test day.
Answer each question to see the explanation. Your score is tallied against the real passing bar at the end.
1. It is illegal for a driver 21 or older to operate a vehicle with a blood alcohol content (BAC) of:
Show answer & explanation
Correct answer: 0.08% or more
It is illegal to drive with a BAC of 0.08% or more if you are 21 or older. The limit is 0.04% for commercial drivers and 0.02% for drivers under 21.
2. Who is required to have a Missouri driver license?
Show answer & explanation
Correct answer: A person who lives in Missouri, is 16 years of age or older, and plans to drive
You must have a Missouri driver license if you live in Missouri, are 16 or older, and plan to drive. New residents who want to drive must also get a Missouri license, even if they hold a license from another state.
3. When you park your vehicle, you are responsible for making sure it:
Show answer & explanation
Correct answer: Is far enough from any travel lane to avoid interfering with traffic and is visible to approaching vehicles
Drivers must make sure their parked vehicles do not become hazards. Park far enough from any travel lane to avoid interfering with traffic, and where vehicles approaching from either direction can see it.
4. When are points added to your Missouri driving record?
Show answer & explanation
Correct answer: When you are convicted of a traffic violation committed while your vehicle was in motion
When you are convicted of a traffic violation committed while your vehicle was in motion, the Department is notified and adds points to your driving record. Accumulating too many points can cost you your driving privilege.
5. What does Missouri law actually say about the right-of-way?
Show answer & explanation
Correct answer: The law says who must yield the right-of-way; it does not give any driver the right-of-way
The law only says who must yield — it never gives anyone the right-of-way. You must do everything you can to avoid striking a pedestrian or another vehicle, regardless of the circumstances.
6. On a highway with four or more lanes (two or more in each direction), you should:
Show answer & explanation
Correct answer: Keep to the right unless passing, letting others merge, or preparing for a legal left turn
On highways with four or more lanes, always keep to the right unless you are passing slower traffic, letting another driver enter safely, or getting ready to make a legal left turn.
7. For a driver under the age of 21, it is illegal to drive with a BAC of:
Show answer & explanation
Correct answer: 0.02% or more
Missouri has a lower limit for young drivers: it is illegal for anyone under 21 to drive with a BAC of 0.02% or more. Even one drink can put a minor over this limit.
8. A conviction for speeding under state law adds how many points to your record?
Show answer & explanation
Correct answer: 3 points
Speeding is a 3-point violation under state law (you may receive two or three points depending on whether the court was municipal, county, or state level). Careless and imprudent driving is 4 points.
9. You are turning from a two-way street onto a one-way street with two lanes. Which lane may you enter?
Show answer & explanation
Correct answer: The left lane or the right lane, whichever is free of traffic
When turning onto a one-way street with two lanes, you may turn into its left lane or right lane, whichever is free of traffic. Begin the turn with your left wheel as close as possible to the yellow dividing line.
10. If you drive for one full year without getting new points on your record, your remaining points are:
Show answer & explanation
Correct answer: Reduced by one-third
Points fade with clean driving: remaining points are reduced by one-third after one year, by one-half after two years, and to zero after three years — though certain convictions stay listed on the record permanently.
11. To reinstate your license after a non-alcohol point suspension or revocation, you must:
Show answer & explanation
Correct answer: Submit proof of insurance (SR-22) and pay a $20 reinstatement fee
For a non-alcohol-related point suspension or revocation, reinstatement requires submitting proof of insurance (SR-22) and paying a $20 reinstatement fee. When reinstated, the Department reduces your total points to four.
12. Compared with a car, a fully loaded tractor-trailer needs:
Show answer & explanation
Correct answer: A much greater distance to come to a complete stop
Tractor-trailers take longer to stop than cars traveling at the same speed. A car at 55 mph can stop in about 130–140 feet, while a fully loaded tractor-trailer may take almost 400 feet.
