The driving knowledge test
The test covers the Colorado Driver Handbook.
Questions include road signs, driving under the influence, driving rules, safety rules, and legal items.
The under-21 page says this test is required at every age.
Read the
handbook
and the
under-21 page.
The DMV does not print how many questions are on the test.
The current written-exam rule requires a correct score of 80% or higher to pass.
An older wording of that rule allowed 0 to 5 wrong at the same 80%.
Read that way, 0 to 5 wrong is a 25-question test.
No later DMV page states a different size.
The current rule is
1 CCR 204-30.
The older wording is in
the earlier driving-school rule.
The handbook describes one test on those topics.
It does not print a separate pass mark for any part.
That reading is from the
handbook.
Where you can take it
- At home. Any Colorado resident can use @Home Driving Knowledge Tests. You need a desktop or laptop with a webcam. You have 60 minutes. The office and school pages do not print a time limit.
- In an office. Book an appointment. A written test will not start in the last 30 minutes before closing.
- At a driving school. You can also test with a third party. That business may charge its own fee.
Home testing is described on the
@Home testing page.
The 30-minute cutoff is in the
handbook.
You may take the written test twice in one day.
You may try again on a later day as many times as you need.
The
under-21 page
states that limit.
The test is offered in English and Spanish, at home and in the office.
The DMV does not offer other languages.
At home, the app can read it aloud in English or Spanish if you have speakers.
In the office, you can bring plug-in headphones so it is read to you.
You may bring a translator for another spoken language.
The DMV can provide a sign-language interpreter.
Language help is on the
@Home page
and the
under-21 page.
If you are younger than 19 and test at home, an adult older than 19 must be your proxy.
The result is emailed to that adult.
The home test takes photos, including at random times, to show who is testing.
Those checks are on the
@Home testing page.
The first home try is free, plus a $5 testing fee and a $1.50 card fee.
That total is $6.50.
A later try is a $5 fee plus a $1.50 card fee, so $6.50 again.
A state DMV fee of $11.50 is charged as well.
The home-test page says you can pay the $11.50 in the office or online, as of April 1, 2026.
Each written retake also has a state fee of $11.50.
The adult permit page says that written retest fee cannot be paid online.
Ask the office which payment rule applies to you.
Fees are on the
@Home page,
the
under-21 page,
and the
adult permit page.
After you pass at home, book a driver license office to get the permit.
You may book any time after you pass.
Bring the pass confirmation on paper or on your phone.
Practice quizzes are online and in the myColorado app.
Details are on the
@Home testing page
and in the
handbook.
Our practice test is shaped like the real one: 25 questions, with 5 misses allowed.
That size is the older rule's 0 to 5 wrong at 80%, not a count the DMV prints.
Practice that test here, free.
A right answer passes without comment. A miss is explained where it happens, because that is the moment it teaches.
