Missouri Permit Test Passing Score: 80% Required and Fail-Fast Scoring (2026)

You must answer 20 out of 25 questions correctly on each section of the Missouri permit test, a passing score of 80%. This allows a margin of error of 5 incorrect answers per section. A 6th incorrect answer causes an immediate fail.

What Is Missouri's Permit Test Passing Score and Structure?

The Missouri permit exam has two separate 25-question tests. Achieve the 80% passing score on both, failing either section requires a retake of that specific part only.

• Written Test (Traffic Laws): 25 questions covering Missouri traffic laws, safe driving practices, and right-of-way rules. Passing requires 20 correct answers.
• Road Sign Test: 25 questions testing recognition of traffic signs, shapes, and colors. Passing also requires 20 correct answers.

The computer uses 'fail-fast' scoring. It stops the test if you reach 20 correct answers (pass) or 6 incorrect answers (fail).

Review the Missouri Driver Guide sample questions before your exam to familiarize yourself with question formats and common topics.

What Are the Most Common Missouri Permit Test Failure Points?

Applicants often fail by one or two questions. Right-of-way questions and sign recognition cause most failures, don't rush.

• A student in Springfield missed her 20th correct answer on the road sign test by confusing the 'Divided Highway Ends' and 'Divided Highway Begins' signs. She scored 19/25, failing by one question.
• An applicant at the St. Joseph exam station missed 6 questions on the written test because he rushed through right-of-way scenarios at intersections. The test ended after his 6th error.
• In Kansas City, a teen passed the written test with 22/25 but failed the road sign section with 19/25. He had to retake only the sign test the next day.

Missouri's Permit Test Fees, Retakes, and Next Steps

The knowledge test is free at Missouri State Highway Patrol exam stations. You only pay for the permit at the license office after passing.

Retake Policy: You can take the written test up to two times per day. There is no limit on total attempts.

After passing both tests and a vision exam, you receive a Driver Examination Record (Form 100). Take this form, your identification documents, and payment to a Missouri DOR license office to receive your instruction permit.

How Do You Avoid Missouri Permit Test Delays and Failures?

Score 23 or higher on practice tests before attempting the real exam. Arrive before 3 PM. Bring exact change or a card for the $12.50 permit fee so you can proceed to the DOR office immediately after passing.

1. Arrive early to avoid long waits. The Jefferson City exam station often has a 90-minute line by 10 AM. Arriving at 8 AM can cut your visit time in half.
2. Memorize sign shapes and colors to avoid the most common failure. The road sign test causes more failures than the written section. Focus on yellow diamond warning signs and red octagon stops.
3. Bring a certified birth certificate, not a hospital copy. The license office in Columbia frequently rejects applicants with unofficial birth documents, causing rescheduling and delaying your permit issuance for weeks.
