A few traffic rules that are particular to Colorado and frequently show up on the test.
DWAI — a lower impairment threshold than DUI
Colorado uniquely charges Driving While Ability Impaired (DWAI) when a driver is impaired to the slightest degree, generally at a BAC of 0.05%. A driver may be convicted of DUI per se at a BAC greater than 0.08%.
Open-container law covers marijuana
It is unlawful to possess an open container of alcohol OR an open container of marijuana in the passenger area of a motor vehicle on a public road — a reflection of Colorado's legalized-cannabis laws.
Mountain-road yielding rule
When two vehicles meet on a steep, narrow mountain road that is not wide enough for both, the vehicle going downhill must yield by backing up to a wider spot, leaving room for the vehicle traveling uphill.
Move Over for stopped vehicles
When you approach any stationary vehicle on a highway with its hazard lights flashing, you must move over one lane when safe. If you cannot move over, or the road is one lane each way, you must slow down.
GDL permit hold and 50-hour log
A minor must hold an instruction permit for 12 months and complete a 50-hour driving log (10 hours at night) before applying for a license. For the first six months of licensure, drivers under 18 may carry no passengers under 21 unless a parent or licensed adult is present.
How to get your Colorado driver's license
The knowledge test is one step in Colorado's licensing process. Here's how the path typically works for a new driver.
Check the age and eligibility requirements
Eligibility in Colorado: 15 with a 30-hour driver education course, 15 years 6 months with a 4-hour driver awareness program, or 16 with no course required for an instruction permit; a minor driver license is available at 16. Have your proof of identity, residency, and any required parental consent ready.
Study the official handbook
Read the Official Colorado Driver Handbook (dmv.colorado.gov) and practice with DMV Ace until you're consistently scoring above 80%.
Pass the knowledge test
The Colorado written test has 25 questions, and you need 20 correct (80%) to pass. Permit/licensing fee: $11.15 state fee for an instruction permit (the first knowledge-test attempt is free at a state driver license office).
Build supervised driving experience
Hold your permit for the period Colorado requires and log supervised driving hours with a licensed adult before you schedule the road test.
Pass the road test and get licensed
After you pass the behind-the-wheel road test, Colorado issues your driver's license — often an intermediate/provisional license first for younger drivers.
Steps are a general guide — always confirm the current process with your local Colorado DMV office.

FAQ
Colorado DMV permit test — common questions
How many questions are on the Colorado DMV Driving Knowledge Test?
- The Colorado knowledge test has 25 multiple-choice questions. You must answer at least 20 correctly (80%) to pass. Colorado does not publish an official time limit, so most testers finish at their own pace.
What's the passing score for the Colorado DMV test?
- 80% — meaning you can miss no more than 5 of the 25 questions. The threshold is the same for first-time testers and retakes.
What's the minimum age to get an instruction permit in Colorado?
- You can get an instruction permit at 15 if you complete a 30-hour driver education course, at 15 years 6 months with a 4-hour driver awareness program, or at 16 with no course required. A minor must hold the permit for 12 months and log 50 hours of driving (10 at night) before getting a license at 16.
Can I take the Colorado knowledge test online?
- Yes. Colorado offers an @Home Driving Knowledge Test you can take online, in addition to testing at a state driver license office or an approved driving school. The first attempt is free at a state office; online and retest attempts carry a fee. Check dmv.colorado.gov for current rules.
How many times can I retake the Colorado test if I fail?
- There is no overall limit on retakes, but if you miss more than 50% of the questions on a first attempt you must wait until the next day to test again. Retest fees apply, and you can schedule another attempt online or at a driver license office.
How much does a Colorado permit cost?
- The state collects about $11.15 to issue an instruction permit. The first knowledge-test attempt is free at a state driver license office; the online @Home test and any retests carry small additional fees. Always confirm current amounts at dmv.colorado.gov.
What is the difference between DUI and DWAI in Colorado?
- DWAI (Driving While Ability Impaired) applies when a driver is impaired to the slightest degree, generally at a BAC of 0.05%, and carries lesser penalties. DUI per se applies at a BAC greater than 0.08%. Colorado's DWAI offense gives the state a lower impairment threshold than many other states.
Does Colorado's open-container law apply to marijuana?
- Yes. It is unlawful to possess an open container of alcohol or an open container of marijuana in the passenger area of a motor vehicle on a public road. This reflects Colorado's legalized-cannabis laws and is tested on the knowledge exam.
