Free Colorado DMV Test Simulator 2026
This DMV Test Simulator is modeled on the Division of Motor Vehicles (DMV) written knowledge exam, whose length the agency does not publish; to pass you need 80% correct. It is a mock test: 25 questions (the DMV does not publish the real test length) 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.
Colorado DMV mock test
Answer all 25 questions first. Nothing is marked until you submit the whole test, so the score shows how ready you are, and then you review every answer with its explanation.
- 25 questions (our test length; the official count is not published)
- To pass: 80% correct
- Skip, go back and change answers until you submit
- Unanswered questions count as wrong
Time: We found no published time limit for the Colorado knowledge test.
What's on the Colorado DMV Test Simulator
You need at least 80% correct. The DMV does not publish the number of questions on the test, so the number you can miss depends on the test you get - on our 25-question simulator that is 5.

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. Colorado prohibits adult drivers from:
- A. Holding or manually using a phone while driving (correct)
- B. Talking through a hands-free accessory
- C. Using a GPS mounted on the dash with voice guidance
- D. Talking with passengers in the vehicle
Why: Since January 1, 2025, Colorado law prohibits drivers from using a mobile device while driving unless they use a hands-free accessory, are contacting law enforcement or the fire department, or are in an emergency.

2. A Colorado minor applying for a driver license must turn in a signed driving log showing:
- A. 40 hours, including 10 at night
- B. 50 hours, including 10 at night (correct)
- C. 50 hours, including 15 at night
- D. 30 hours, including 5 at night
Why: Minors must hold an instruction permit for 12 months and submit a signed log of 50 hours of driving, 10 of them at night.

3. What must you do when you see this sign?
- A. Slow down and go if no one is coming
- B. Stop fully, then go when it is safe (correct)
- C. Stop only if cross traffic is coming
- D. Stop, then go ahead of cross traffic
Why: This is a STOP sign (red octagon). You must come to a complete stop at the stop line, crosswalk, or before the intersection, then proceed only when it is safe.

4. What does 'implied consent' mean for drivers?
- A. You agree to obey all traffic laws when you drive
- B. You agree to chemical tests if arrested for DUI (correct)
- C. You let police search your car at any stop
- D. You may refuse testing with no penalty
Why: Implied consent laws mean that by driving on public roads, you have already consented to chemical tests (breath, blood, urine) if you are lawfully arrested for suspected DUI. Refusing has serious consequences including license suspension.
5. If your vehicle's accelerator sticks while driving, you should:
- A. Shift into park and pull the parking brake
- B. Shift to neutral, brake, and steer to safety (correct)
- C. Switch off the engine and remove the key
- D. Keep driving and call for help on your phone
Why: Shift to neutral (to disconnect engine power), then apply brakes steadily to slow the vehicle. Steer to a safe location. Only turn off the ignition if other methods fail - as this can lock the steering column in older cars.
6. In most states, which left turn may you make on a steady red light after a full stop, if no sign forbids it?
- A. From a two-way street onto another two-way street
- B. From any street when no oncoming car is in sight
- C. From a two-way street into a store's driveway
- D. From a one-way street onto another one-way street (correct)
Why: Most states allow a left turn on red from a one-way street onto another one-way street that carries traffic to the left. You must stop fully and yield to pedestrians and traffic first.
