What the Missouri driving test covers and how it's scored

Missouri's driving test has two parts: a written exam on traffic laws and road signs, and a behind-the-wheel driving test. You take the written test first at a Missouri Department of Revenue office. If you pass, you schedule the driving test at the same location, usually within a few days or weeks depending on how busy your local office is.

The written test has 25 questions about Missouri traffic laws, right-of-way rules, and what road signs mean. You need 18 correct answers to pass. The driving test lasts about 20 to 30 minutes. An examiner sits in the passenger seat while you drive on public roads near the testing location. They score you on steering control, braking, turning, lane changes, parking, and how you respond to traffic and pedestrians.

You fail the driving test if you commit a critical error — running a red light, hitting a curb, or causing an unsafe situation — or if you accumulate too many minor mistakes. The examiner will tell you whether you passed or failed before you leave. If you fail, you can retake the test, but you must wait at least one day before scheduling another attempt.

Key Takeaways

  • Missouri's written test covers 25 questions on traffic laws and signs, and you need 18 correct to pass.
  • The driving test lasts 20 to 30 minutes on public roads with an examiner in the passenger seat scoring your vehicle control and decision-making.
  • You must pass the written test before you can schedule the driving test at the same Department of Revenue office.
  • One critical error during the driving test — such as running a red light or hitting a curb — results in an automatic fail.
  • You can retake either test, but you must wait at least one day between attempts and pay the test fee again.

How to prepare for the written test

The Missouri Department of Revenue publishes a free study guide called the Missouri Driver Guide, available as a PDF on their website or in print at any office. It covers every topic on the written test: speed limits, right-of-way, parking rules, what each road sign means, and how to handle different driving situations. Read through it once, then focus on the sections where you feel weakest.

Practice tests are the most effective way to prepare. The Missouri Department of Revenue website offers free practice tests that mirror the real exam's format and difficulty. Take the practice test multiple times until you score 20 or higher consistently. Many people find that taking it three or four times catches the questions they missed the first time.

On test day, bring your current ID, proof of your Social Security number, and proof of your Missouri address (a utility bill or lease works). Arrive 15 minutes early. The test is offered in English and Spanish. You have 30 minutes to complete it. If you fail, you can retake it the same day at most offices, though you'll pay the fee again.

What to expect during the behind-the-wheel driving test

Before the test starts, the examiner will ask you to show your license or permit, then walk around the vehicle with you to check that the lights, wipers, horn, and mirrors work. They'll ask you to demonstrate that you can operate the parking brake and adjust the seat and mirrors. This takes about five minutes. If something doesn't work, you fail when ready, so check your vehicle the day before.

Once you're on the road, the examiner will direct you where to go using straightforward instructions: "Turn left at the next light" or "Pull into that parking lot." You control the route by following their directions. They're watching how smoothly you accelerate and brake, whether you check your mirrors and blind spots, how you handle turns, and whether you obey traffic signs and signals. They also watch how you react when something unexpected happens — a pedestrian stepping into the street, another car cutting you off, or a sudden stop.

The test includes at least one parking maneuver, usually parallel parking or backing into a space. You'll also make several turns and drive on roads with different speed limits. The examiner is not trying to trick you; they're checking whether you drive safely and follow the rules. Speak clearly if you have questions, and don't be afraid to ask the examiner to repeat an instruction.

Common reasons people fail the driving test

The most common critical errors are running a red light or stop sign, failing to yield the right of way, and hitting a curb or object. These are automatic failures because they create when ready danger. Hitting another vehicle or causing an accident also results in an automatic fail.

Minor errors that add up include rolling through a stop sign instead of coming to a complete stop, not signaling before turning or changing lanes, drifting between lanes, and not checking mirrors frequently enough. You can make a few minor mistakes and still pass, but if you accumulate too many — usually more than five or six — you fail. Parallel parking is also a common sticking point; if you can't position the car within the lines after three attempts, you fail that portion.

Nervousness causes some people to forget basic skills they use every day. If you feel panicked during the test, take a breath and remember that the examiner expects some nervousness. They're not looking for perfection; they're looking for safe, legal driving. If you make a small mistake, don't dwell on it — focus on the next task.

How to practice before your test appointment

Practice driving in the area where you'll be tested if possible. Many Missouri offices test on the same roads repeatedly, so familiarity helps. Drive those roads at different times of day to see how traffic changes. Practice parallel parking in an empty parking lot using cones or chalk to mark the space.

Practice with someone who can give you honest feedback — a parent, friend, or professional instructor. Tell them to point out when you forget to signal, drift between lanes, or brake too hard. Many people have habits they don't notice until someone else mentions them. A professional driving instructor can identify problems faster and teach you how to fix them. Lessons typically cost $50 to $100 per hour in Missouri, and even two or three lessons can make a real difference if you're nervous or unsure about specific maneuvers.

The week before your test, drive in different conditions: heavy traffic, residential streets, roads with hills, and parking lots. The more situations you've practiced, the fewer surprises you'll face on test day. Get a good night's sleep the night before, eat breakfast, and leave early so you're not rushed.

What happens if you fail and need to retake the test

If you fail the written test, you can retake it the same day at most offices. You pay the test fee again — currently $10 for the written test and $10 for the driving test in Missouri, though fees can change. You have 30 minutes to complete the written test again.

If you fail the driving test, you must wait at least one day before scheduling another attempt. You can schedule your next test at the same office or a different one. You'll pay the driving test fee again. There's no limit to how many times you can retake the test, but each attempt costs money and takes time. Most people pass on the second or third attempt if they practice between tests and address the specific mistakes the examiner noted.

When you retake the driving test, ask the examiner what you did wrong the first time. They'll tell you which maneuvers or decisions caused problems. Focus your practice on those specific areas. If you failed because of parallel parking, spend extra time on that. If you failed because you didn't check your mirrors, make mirror checks a habit before every turn and lane change.

Frequently Asked Questions

Can I use my phone or GPS during the driving test?

No. You cannot use your phone, GPS, or any navigation device during the test. The examiner will give you all directions verbally. If you're worried about getting lost, practice the route beforehand or ask the examiner to repeat instructions if you don't understand where to turn.

What if my car breaks down or has a mechanical problem during the test?

If your vehicle has a mechanical failure during the test — the engine stalls, brakes fail, or lights stop working — the test is stopped and rescheduled. You won't be marked as a failure. However, you're responsible for providing a safe, working vehicle, so check everything before you arrive.

Do I need to take a driver's education course before the driving test?

No. Missouri does not require a driver's education course to take the driving test. However, if you're under 18, you must hold a learner's permit for a certain period and log supervised driving hours. Check the Missouri Department of Revenue website for the current requirements for your age group.

How long does it take to get my license after I pass both tests?

You receive your license the same day you pass the driving test. The examiner will take your photo and issue your license before you leave the office. You can start driving alone when ready after passing.

What if I'm nervous and fail because of anxiety?

Many people feel nervous during the test, and examiners understand this. If anxiety is severe, consider taking a few professional driving lessons to build confidence. Some people also find it helpful to practice deep breathing or visualization before the test. Remember that you've practiced these skills many times; the test is just doing them in front of someone else.
