Free Colorado DMV Practice Test 2026
These sample questions come from the same bank we use for full practice tests, and each one is drawn from the official Colorado driver handbook. Every answer explains why it is right — and why the tempting wrong answer is wrong, which is usually where the score is actually lost. For the current length and passing score of the Colorado Division of Motor Vehicles test, check the agency directly.

5 sample questions with answers
Signs & Signals
1. How can you identify an HOV lane on the roadway?
- A white diamond painted on the roadway
- A yellow diamond painted on the roadway
- Double-broken yellow lines
Correct answer: A white diamond painted on the roadway
Why: HOV lanes are specifically identified by a white diamond painted on the roadway, along with signs that specify vehicle types and occupant requirements.
Right-of-Way Rules
2. You need to merge into or cross a designated bike lane to make a turn. What must you do?
- Yield the right-of-way to bicyclists in the bike lane
- Proceed if you can complete the turn before any bicycle reaches you
- Signal your intention and merge slowly to give bicyclists time to stop
Correct answer: Yield the right-of-way to bicyclists in the bike lane
Why: The handbook specifically states that drivers must yield the right-of-way to bicyclists in a designated bike lane when merging with or crossing a bike lane to turn. This is a specific right-of-way rule that protects bicyclists.
Alcohol & Drugs
3. What happens to your Blood Alcohol Concentration (BAC) once alcohol is in your bloodstream?
- Only the passage of time will lower it, dropping about 0.015% per hour on average
- Coffee, cold showers, and exercise will help lower it faster
- Eating food and drinking water will significantly reduce it within 30 minutes
Correct answer: Only the passage of time will lower it, dropping about 0.015% per hour on average
Why: The handbook clearly states that only the passage of time will make a person sober, and on average, BAC drops by 0.015% per hour through normal bodily processes.
Speed & Following Distance
4. Why are reduced speed limits used in construction work zones?
- To give drivers more time to understand and react to changing conditions and safely navigate through equipment and workers
- To reduce vehicle emissions and noise levels that could disturb construction workers
- To prevent damage to construction equipment from debris kicked up by fast-moving vehicles
Correct answer: To give drivers more time to understand and react to changing conditions and safely navigate through equipment and workers
Why: The handbook explains that reduced speed limits give drivers more time to understand and react to information and safely navigate through the complex assortment of devices, workers, and equipment.
Parking Rules
5. How close to a fire hydrant can you legally park?
- Within 15 feet
- At least 15 feet away
- Within 30 feet
Correct answer: At least 15 feet away
