Free Louisiana OMV Test Simulator 2026
This DMV Test Simulator is modeled on the Office of Motor Vehicles (OMV) written knowledge exam, which has 40 questions; to pass you need 32 of 40 correct (80%). It is a mock test: 40 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.

- A. 0.00%
- B. 0.02% (correct)
- C. 0.04%

2. Louisiana law requires an approved helmet for bicycle riders and passengers under what age?
- A. Age 8
- B. Age 10

3. Your gas pedal is stuck and you switch off the engine to slow the car. What should you expect?
- A. The brakes will stop working completely
- B. Steering and braking will take more effort (correct)
- C. The car will speed up for a few seconds
- D. The car will come to a stop almost at once
Why: With the engine off you lose power steering and power brake assist, so the wheel and pedal feel much heavier. They still work - push harder and steer to a safe stop.
4. Which of the following is NOT a legal reason to use your horn?
- A. To warn a driver drifting into your lane
- B. To express frustration at another driver (correct)
- C. To alert a child about to run into the road
- D. To warn others on a blind mountain curve
Why: Horns are safety devices used to warn others of danger. Using your horn out of frustration or anger is not a legal use and can be considered aggressive driving in many states.
5. What is the purpose of a broken white line between lanes?
- A. Lanes are one-way only
- B. Lane changes are permitted when safe (correct)
- C. You may not change lanes or pass here
- D. Traffic moves in opposite directions
Why: Broken (dashed) white lines separate lanes of traffic moving in the same direction. You may change lanes when it is safe to do so.
6. How do prescription and over-the-counter medications affect driving?
- A. Legal medicines are always safe to drive on
- B. Only prescription drugs can impair driving
- C. Many cause drowsiness - check the label first (correct)
- D. Only if you take more than the dose listed
Why: Many legal medications - including antihistamines, sleep aids, and pain relievers - can cause drowsiness, dizziness, or slowed reactions. Always read warning labels and avoid driving if a medication may impair you.
