Getting licensed in Missouri — the practical details

The questions people actually ask about the Missouri process, answered from official state sources.

How much is a Missouri driver license?

The Department of Revenue's fee table lists the full Class F license at $16.50 for a card valid up to three years and $33 for one valid up to six, with the price set by your age on the day of the transaction rather than by preference. The Class F instruction permit is $10 and the intermediate license is $14. A footnote on the same table notes that applicable fees for written and road tests are not included. Confirm the amounts on that fee page before you go.

What are the age minimums on Missouri's three licensing steps?

Fifteen for the Class F instruction permit, sixteen for the intermediate license, and eighteen for the full Class F driver license — the three steps the Driver Guide labels Step One, Step Two and Step Three of the Graduated Driver License program. The Department's web fee table repeats the same minimum ages next to each price. The Driver Guide's own Chapter 1 chart adds a separate student permit row, also at a minimum age of 15.

How long is the Missouri knowledge test and what score passes it?

The Driver Guide's introduction sets it at 25 multiple-choice questions and says you must correctly answer 20 to pass. The Department of Revenue's licensing FAQ states the same standard as 80%, written out as 20 questions out of 25. The guide adds that every question comes directly from information found in the guide, that there are no trick questions, and that the test is not an open book test.

Does Missouri publish how many wrong answers are allowed?

Not as its own figure. The documents fetched for this guide publish a total and a pass line — 25 questions, 20 correct — and leave the miss allowance to be worked out from those two numbers rather than printing it. That matters when you are checking a claim you read elsewhere: any specific number of permitted misses for Missouri is arithmetic on the published pair, not a separately published rule.

Is the Missouri written exam timed?

No duration appears in any document fetched for this guide. A case-insensitive search of the full Driver Guide for "time limit", "minutes to complete" and "allotted" returns nothing tied to the written test, and the Department of Revenue and Highway Patrol pages read here name no minute count either. The untimed label records that silence, not an official allowance.

Do I need an appointment to be tested in Missouri?

The Highway Patrol's Driver Examination Division says appointments are not necessary for the driving skills portion of the full driver (operator) license, but are necessary for a commercial driver license skills test, for which it publishes phone numbers by location. The same page warns in capital letters that arriving before closing time does not guarantee that a written or driving skills test will be given, because tests are given based on personnel availability and the volume of applicants.

What vision standard does Missouri apply?

An acuity test and a peripheral (side) vision test are given whenever you apply for any new or renewal driver license or permit. The standard minimum acuity is at least 20/40 with either or both eyes and the standard minimum peripheral reading is at least 55 degrees in each eye or 85 degrees in one eye. Below those, an examiner issues a vision exam form for your eye specialist or physician. If both natural and corrected acuity are worse than 20/160, or peripheral combined is worse than 70 degrees, you cannot take the driving test and cannot have a driver license.

How is the Missouri driving test scored?

The examiner subtracts points for driving errors and Chapter 2 fails you if you lose more than 30 points. Separately, the Department's FAQ says an applicant who already holds a valid instruction permit needs a score of 70% or better; no fetched document states the point total that score starts from, so the two figures are published separately rather than as one converted into the other. Five errors fail you outright regardless of the total: causing a crash with another vehicle, hitting a pedestrian, driving so dangerously you might have caused a crash, violating a traffic law, or refusing to drive as the examiner asks. The graded tasks include a parallel park in a space 25 feet long and seven feet wide, within 18 inches of the curb and within two minutes.

Where does the Missouri license card itself come from?

From central issuance, not from the window. The Department of Revenue implemented a central issuance system for driver licenses and nondriver IDs in December 2012, replacing the over-the-counter system in place since the 1990s, and the finished card is mailed to the address on your application. The counter itself is run by a contractor: the Department oversees more than 170 license offices, each operated by independent contractors under competitive bid.

How long can an out-of-state license be expired and still waive Missouri's tests?

184 days. The Department of Revenue lets you surrender a valid out-of-state license, or one expired 184 days or less, to waive the Missouri skills and written tests — but its FAQ states that all applicants are required to pass the Missouri road sign recognition and vision tests, so the waiver never covers those two. Commercial driver license holders must transfer within 30 days of transferring residency, and the other state's license, permit or nondriver ID is invalidated on transfer.

How long is a Missouri driver license valid?

It depends on your age at the transaction: a driver 18 to 20 gets a three-year license, 21 to 69 a six-year license, and 70 or over a three-year license again, each expiring on the applicant's date of birth in the relevant year. An applicant who is not a U.S. citizen may receive a shorter term based on the expiration of the documents submitted. You may renew up to six months early, and every renewal requires the vision and road sign recognition tests.
