How many questions are on the Missouri DOR knowledge test?
The test has 25 multiple-choice questions with one overall score — no separate sections. Missouri also administers a separate road signs test at the same MSHP exam station visit.
What is the passing score?
You need 80% overall — that's 20 out of 25 correct. One combined score. No separate section thresholds.
What happens if I fail?
You must wait until the next business day to retake the written knowledge test. Missouri does not charge an additional fee to retake it. If you fail the driving skills test, you may take one driving test per day.
Is the test timed?
No, the real Missouri DOR test has no time limit. Take your time and read carefully. Our practice exam uses a 25-minute timer to simulate slight pressure, but the real test lets you go at your own pace.
How old do I need to be for a learner's permit?
Age 15 — no driver's education required in Missouri. You must hold the permit for at least 182 days (6 months) before applying for an intermediate license.
What documents do I need to bring?
For a first-time permit or license, bring:
- Proof of identity — birth certificate, passport, or other government-issued ID
- Social Security card or document showing your SSN
- Two proofs of Missouri residency — utility bill, bank statement, lease, etc.
- Parent/guardian must be present if you're under 18
Does Missouri use "DUI" or "DWI"?
Missouri uses DWI — Driving While Intoxicated. The test will use DWI terminology, not DUI. Key numbers: 0.08% BAC limit (21+), 0.02% BAC (under 21), 0.15%+ triggers enhanced penalties. Refusing a chemical test = automatic 1-year license revocation.
Is cannabis legal in Missouri?
Yes — but driving impaired is still illegal. Missouri legalized medical marijuana in 2018 and recreational marijuana in November 2022 (Amendment 3). However, driving under the influence of marijuana is an DWI offense. There is no legal THC limit like the 0.08% BAC for alcohol — prosecutors must prove impairment. Medical marijuana cardholders cannot be charged simply for having THC in their system, but can still be charged if actually impaired.
How many hours of practice driving do I need?
40 hours of supervised behind-the-wheel driving, including at least 10 hours at night. If you are under 16, your accompanying supervisor must be a parent, grandparent, or legal guardian — or a person at least 25 years old who has been licensed for a minimum of three years and has written permission from your parent/guardian. Once you turn 16, any licensed driver 21 or older may supervise.
What's the intermediate license curfew?
Intermediate License curfew: 1:00 a.m. to 5:00 a.m. (until you can apply for a full license at age 18). Missouri GDL: Instruction Permit (learner) → Intermediate License (intermediate with curfew & passenger limits) → Full License (full license at age 18).
