In Missouri you can get an instruction permit at age 15. The written test has 25 questions, and you need 20 correct, which is 80 percent. Rules and fees change, so as of 2026 treat this guide as a starting point and confirm everything on the official site. The official source is the Missouri Department of Revenue and the Missouri Driver Guide.
Age and test format
The minimum age is 15. The driver exam has four parts: a written test, a vision test, a road sign test, and a driving test. The written test has 25 multiple-choice questions, and you must answer 20 correctly.
Practice hours and time with the permit
- Teens need 40 hours of supervised driving, with at least 10 at night.
- Teens hold the permit at least 6 months (182 days) before moving to the intermediate license.
Keep a log. It is much easier to write down each drive than to remember months later.
Rules you should know
- School buses: when the red lights and stop arm are out, stop on two-lane roads from both directions. Amber lights flash 500 feet before a stop.
- Blood alcohol limits: 0.08 for adult drivers and 0.02 for drivers under 21.
- Signal at least 100 feet before you turn or change lanes.
- Speed limits: 25 mph in towns unless posted, 70 mph on rural interstates, and at least 40 mph on interstates.
- Move over or slow down for stopped emergency vehicles with flashing lights.
- Stop 15 to 50 feet before railroad tracks when lights flash or a gate is down.
The Missouri Driver Guide uses the three-second rule for following distance. Always label your notes with the state if you study for more than one.
Why details matter
Test writers like numbers: distances, ages, hours, and limits. When you read the manual, highlight every number and make a one-page summary. Review it before each practice test.
A simple study plan
- Read the Missouri Driver Guide in short sessions, one chapter at a time.
- Learn road signs by shape and color, then by meaning.
- Take practice tests and explain every wrong answer out loud.
- Repeat your weak topics, such as right of way or the point system.
- Sleep well the night before and bring your documents.

Tips for parents and guardians
Parents can make a big difference without taking over. Sit down with your teen once a week and ask them to explain a rule in their own words. If they can teach it back to you, they probably know it.
Look at the practice driving log together, plan a mix of daytime, night and bad weather drives, and keep the first drives in quiet places such as empty parking lots or calm neighborhood streets. Stay patient. Everyone is nervous at the start.
Common mistakes to avoid
- Studying only signs and skipping the numbers and rules.
- Using a manual from a different state.
- Waiting until the night before to study.
- Rushing through questions without reading every answer.
- Forgetting to check the document list for your MO visit.
On test day
Arrive early, bring everything on the official list, and take a few slow breaths before you begin. Read each question twice. If a question is confusing, move on to the next one if the test allows it and come back later. Staying calm is part of passing.
DMVZone practice questions are for study only. They are not the real test questions, but they help you practice the kinds of topics the test covers.
