Free Tennessee TDOSHS Test Simulator 2026
This DMV Test Simulator is modeled on the Department of Safety and Homeland Security (Driver Services Division) (TDOSHS) written knowledge exam, which has 30 questions; to pass you need 24 of 30 correct (80%). It is a mock test: 30 questions, the length of the real test, scored to the 80% pass mark. Answers are marked only when you submit the whole test, then you review every question with its explanation. Every question includes an explanation, so you learn the rule behind each answer - not just whether you got it right.

1. A train is coming as you reach a railroad crossing. Where does Tennessee require you to stop?
- A. 5 to 10 feet from the tracks
- B. Right at the nearest rail
- C. 15 to 50 feet from the tracks (correct)
- D. 100 to 150 feet from the tracks

- A. 3 points
- B. 12 points
- C. 6 points (correct)
- D. 15 points

3. What color are warning signs?
- A. Red
- B. White with black letters
- C. Yellow or orange (correct)
- D. Blue or green
Why: Warning signs are yellow (standard warnings) or orange (construction/work zones). They alert drivers to potential hazards ahead such as curves, intersections, or pedestrians.
4. A warning sign showing an arrow splitting into two directions around a vertical line indicates:
- A. A divided highway begins ahead (correct)
- B. A fork where you must choose a route
- C. A passing lane opens ahead
- D. Two-way traffic begins ahead
Why: This sign warns that a divided highway begins ahead - a median or barrier will separate the opposing lanes. Keep right of the divider.
5. When you reach an intersection with a flashing red light in your direction and a flashing yellow in the cross direction, you must:
- A. Slow down and go - the cross traffic has to stop
- B. Stop, then go when safe - cross traffic won't stop (correct)
- C. Stop and wait until your light turns solid green
- D. Stop, then go first - cross traffic must yield
Why: A flashing red light works like a stop sign: stop completely, then go when safe. The cross traffic with a flashing yellow only needs to slow and proceed with caution - they do not stop, so you must yield to them.
6. For adult drivers (21+), what Blood Alcohol Concentration (BAC) is the legal limit in most states?
- A. 0.05%
- B. 0.08% (correct)
- C. 0.04%
- D. 0.02%
Why: In most US states, a BAC of 0.08% or higher is legally considered driving under the influence (DUI) for drivers 21 and older. Always check your state's specific laws.
