Free Missouri DOR Practice Permit Test - Practice Test 3 2026
This Practice Test 3 is modeled on the Department of Revenue (DOR) written knowledge exam, which has 25 questions; to pass you need 20 of 25 correct (80%). Besides the 25-question written test (20 correct to pass), there is a separate road sign test. These 25 questions rotate through traffic laws, road signs, and right-of-way - the core topics the DOR tests most heavily. Every question includes an explanation, so you learn the rule behind each answer - not just whether you got it right.

Sample questions from this test, with answers
Want to test yourself first? Take the test above before reading these. Every answer below is checked against the source shown.
1. When you must stop at a railroad crossing in Missouri, where should your vehicle stop?
- A. 15 to 50 feet before the tracks (correct)
- B. 5 to 10 feet before the tracks
- C. 50 to 100 feet before the tracks
- D. Right at the edge of the tracks
Why: Stop between 15 and 50 feet from the tracks when the red lights flash or the gate is down. Never drive around a lowered gate.

2. A car at 55 mph can stop in about 130-140 feet. About how much distance might a fully loaded tractor-trailer need at the same speed?
- A. About 150 feet
- B. About 200 feet
- C. Almost 400 feet (correct)
- D. Over 1,000 feet
Why: A fully loaded tractor-trailer may need almost 400 feet to stop, far more than a car. Never cut in front of a big truck and then slow down.

3. A flagger in a work zone turns the paddle so the word SLOW faces you. What should you do?
- A. Stop until the flagger waves you on
- B. Proceed slowly and watch for workers (correct)
- C. Keep your speed - you have the right of way
- D. Speed up to clear the work zone quickly
Why: Flaggers use STOP/SLOW paddles to control traffic. SLOW means you may move ahead at a reduced speed with care; STOP means stop.
4. Why should you use low beams instead of high beams when driving in fog?
- A. High beams drain the battery faster in damp air
- B. Low beams make your car look larger to others
- C. High beams are only allowed on freeways
- D. High beams reflect off the fog and cause glare (correct)
Why: Fog reflects the bright light of high beams back at you, making it harder to see. Low beams light the road with less glare. Also slow down.
5. On a freeway, a green sign with a number in a small square (such as 'EXIT 25') refers to:
- A. The posted speed limit on the exit ramp
- B. The exit number, often the mile marker (correct)
- C. The route number of the highway
- D. The distance to the next city in miles
Why: Exit number signs identify highway exits. In most states the exit number corresponds to the nearest mile marker, helping you judge distance to your exit.
6. The single most effective way to avoid an alcohol-related crash is to:
- A. Drink coffee and wait 30 minutes before driving
- B. Drive slowly and stay in the right lane
- C. Not drive at all after drinking any alcohol (correct)
- D. Stay under 0.08% by counting your drinks
Why: There is no safe way to drive after drinking. The only sure prevention is to not drive at all after consuming alcohol - arrange a designated sober driver, taxi, or rideshare instead.
