The Cost of the Learner's Permit Knowledge Test in St. Louis

The written knowledge test for a Missouri learner's permit costs $10.50 in St. Louis. This fee covers the test itself only — not the permit document, which is issued separately and included in your overall permit cost. You pay the $10.50 at the time you take the test at a Missouri Department of Revenue office.

The total cost to obtain a learner's permit in Missouri is higher than the test fee alone. When you pass the knowledge test, you also pay a permit issuance fee. The combined cost for a learner's permit (test plus permit document) runs approximately $10.50 to $13, depending on the specific office and whether you are renewing or obtaining your first permit.

Payment is cash or card at the point of service — you cannot pay online or by mail for the test itself. Bring enough money to cover the $10.50 test fee plus any additional permit fees on the day you test.

  • The knowledge test for a learner's permit in St. Louis costs $10.50 and must be paid in cash or card at the Department of Revenue office on test day.
  • The $10.50 covers only the test; the permit document itself carries an additional issuance fee, bringing your total cost to roughly $10.50 to $13.

  • St. Louis has multiple Department of Revenue locations; the test fee is the same at all of them, but hours and wait times vary.

Where to Take the Test and What to Bring

In St. Louis, you take the learner's permit knowledge test at a Missouri Department of Revenue office. The main St. Louis location is at 301 West High Street, Jefferson City is the state capital office, but St. Louis city and St. Louis County each have their own Department of Revenue locations. You can also test at satellite offices in some suburban areas.

Before you go, bring your Social Security number, proof of identity (a passport, birth certificate, or state ID), and proof of residency (a utility bill, lease, or bank statement with your current address). You also need to bring payment for the $10.50 test fee in cash or a debit/credit card. Do not assume a specific office takes only one payment method — call ahead to confirm.

No appointment is required for the knowledge test in Missouri. You walk in during business hours, complete the written exam, and pay the fee. However, wait times can be long during peak hours (typically mid-morning and early afternoon on weekdays). Arriving early in the morning or on a weekday afternoon often means a shorter wait.

What the Test Covers and How It Works

The Missouri learner's permit knowledge test has 25 questions. You must answer at least 19 questions correctly (76 percent) to pass. The test covers road signs, right-of-way rules, speed limits, parking, safe driving practices, and Missouri-specific traffic laws.

The test is administered on a computer at the Department of Revenue office. You sit at a terminal, read each question, and select your answer. The system scores your test when ready. If you pass, you proceed to pay the permit issuance fee and receive your permit. If you fail, you can retake the test the same day or return another day — there is no waiting period between attempts in Missouri, though you pay the $10.50 fee each time you test.

The test is offered in English only. If you need the test in another language, contact the St. Louis Department of Revenue office directly to ask about accommodations or interpreter services.

Permit Issuance Fee After You Pass

Once you pass the knowledge test, you pay a second fee for the permit document itself. This issuance fee varies slightly depending on the permit type and your age. For a standard learner's permit, the fee is typically $3 to $5. Combined with the $10.50 test fee, your total out-of-pocket cost is roughly $13.50 to $15.50.

The permit is valid for one year from the date of issue. If you do not obtain your full driver's license within that year, you can renew the learner's permit, though you will need to retake the knowledge test and pay both fees again.

Retaking the Test if You Fail

If you do not pass on your first attempt, you can retake the test when ready at the same office. You pay the $10.50 fee again for each attempt. There is no mandatory waiting period between retakes in Missouri, so you can test multiple times in one day if you choose, though most people study and return another day.

Many people fail because they did not study the Missouri Driver Guide beforehand. The guide is free and available online at the Missouri Department of Revenue website or in print at any Department of Revenue office. Spending 30 minutes to an hour reviewing the guide before your test significantly improves your chances of passing on the first attempt and saves you the cost of a retake.

St. Louis Department of Revenue Office Locations and Hours

St. Louis city and St. Louis County each have Department of Revenue offices. The St. Louis city office is located downtown; the St. Louis County office serves the suburbs. Both offices administer the learner's permit knowledge test and charge the same $10.50 fee.

Hours vary by location. Most offices are open Monday through Friday, 8 a.m. to 5 p.m., with some closing for lunch. A few satellite locations have limited hours or are open only certain days of the week. Before you go, call the specific office or check the Missouri Department of Revenue website to confirm current hours, as they can change seasonally or due to staffing.

If you cannot reach an office by phone, you can visit the Department of Revenue website and use their office locator tool to find the nearest location, hours, and contact information.

Payment Methods and What Happens After You Pay

The $10.50 test fee is paid at the time you take the test. Most St. Louis Department of Revenue offices accept both cash and card (debit or credit). A few older or smaller satellite offices may accept cash only, so calling ahead to confirm payment methods is wise if you plan to use a card.

After you pass the test and pay both the test fee and the permit issuance fee, you receive your learner's permit when ready. The permit is a physical document you can use right away. You do not need to wait for it to arrive by mail — you walk out with it the same day.

Keep your permit in a safe place. If you lose it, you will need to pay a replacement fee (typically $3 to $5) and return to a Department of Revenue office to request a duplicate.
