Colorado 50-Hour Driving Log Sheet: Form DR 2324 and Submission

Colorado’s 50 hour driving log is Form DR 2324, and a teen under 18 can’t get a license without turning one in. The log has to show at least 50 hours of supervised practice behind the wheel, with no fewer than 10 of those hours driven at night, and it has to be signed by a parent, guardian, or other responsible adult who is at least 21.¹ The requirement comes from C.R.S. 42-2-104, which also requires the teen to have held an instruction permit for a full 12 months before the license is issued.²

What the Log Has to Prove

Two numbers matter at the DMV counter: total hours and night hours. The totals on the back of your log must come to at least 50 and at least 10, respectively. If either falls short, the application is rejected. The statute frames the rule as a minimum of 50 total with at least 10 at night, so the other 40 are expected to be daytime practice but aren’t called out as a separate quota.²

Use Form DR 2324, downloadable from the Colorado DMV website. The state will also accept a log from an approved commercial driving school, a driver education program, or a third-party testing organization. Logs kept in the RoadReady app count too, but they still have to be printed and signed before you submit them.³

Whose Hours Count

Only hours driven with the right supervisor count on the log. The default supervisor is whoever signed the Affidavit of Liability (Form DR 2460) for the permit, typically a parent, stepparent, grandparent with power of attorney, guardian, or foster parent. That person has to hold a valid Colorado driver’s license and ride in the front passenger seat during every session.⁴

If the affidavit signer doesn’t hold a valid Colorado license, they can name an alternate permit supervisor, who must be at least 21 and licensed in Colorado.⁴ There’s a distinction here that catches families off guard. The affidavit signer can also authorize other licensed adults 21 or older to ride along so the teen can drive legally, but time behind the wheel with those extra adults doesn’t count toward the 50-hour total. Only hours driven with the affidavit signer or the designated alternate supervisor count.

Filling Out Form DR 2324

Put the student’s name and permit number at the top. Each row below records a single practice session with these columns:

Date the session took place.
Verifier’s initials, written in by the supervising driver to confirm the session happened.
Total driving time for the session.
Night driving time for the session.
Comments (optional) for routes, conditions, or skills.

Fill in each row the day you drive. Reconstructing weeks of practice from memory is where logs start looking suspicious to the clerk reviewing them, and sloppy math or blank entries that make totals look inflated are the most common reason a log gets questioned at submission.

Totals and Signature on the Back

Once practice sessions reach the 50-hour minimum, write the grand total driving time and the grand total night driving time on the back of the final log sheet. A parent, guardian, or responsible adult then signs and dates the back to certify the hours are accurate.¹ Without both grand totals and a signature, the form won’t be accepted. Add up the night column and the total column one more time before you sign; if night hours come in under 10 or the total under 50, the application is rejected on the spot.

The Log Doesn’t Need to Be Notarized

Families sometimes mix up Form DR 2324 with Form DR 2460, the Affidavit of Liability and Guardianship. The affidavit has to be signed in front of a DMV employee or a notary public.⁵ The driving log does not. The parent or responsible adult just signs the back. If anyone tells you the log itself needs notarization, they’re thinking of the other form.

Submitting the Log

Colorado accepts the completed log two ways when the teen is ready to upgrade from permit to license.

Online

If nothing about the teen’s name or address has changed and you’re not asking for a behind-the-wheel training exemption, you can upload a scanned copy of the signed log through the DMV’s online upgrade. Make sure the student’s name is legible, both grand totals are filled in, and the signature is on the back.³

In Person

At a DMV appointment, bring the printed log signed by a parent, guardian, or responsible adult 21 or older, with the grand totals of driving time and night driving time filled in. If the teen’s name has changed, bring supporting documents. If the address has changed, bring two different documents showing a current Colorado address, both dated within the past year.³

When 50 Hours Isn’t Enough

The 50-hour log by itself only covers teens who are at least 16 years and 6 months old. Younger permit holders have additional requirements, and families in rural areas may have to log more hours instead of attending a school.

Under 16 years and 6 months: six hours of in-car training with an approved third-party driving school, on top of the 50-hour log.³
16 years and 6 months or older: the six-hour behind-the-wheel training requirement is waived.
More than 30 miles from an approved full-time driving school: 12 hours of in-car driving with a supervising driver substitutes for the six-hour school requirement, bringing the total logged hours to 62.²

If you’re claiming the 30-mile exemption at an in-person appointment, bring a printed map showing the route from home to the nearest full-time driving school.

If the Teen Turns 18 Before the Year Is Up

If the 18th birthday arrives before the permit has been held for a full year, the driving log doesn’t need to be submitted at all.³ Applicants 18 and older have no minimum permit-holding period, don’t need the Affidavit of Liability, and can go straight to the driving test. For a teen close to 18 whose log is incomplete, waiting a few weeks can bypass the paperwork entirely, even though the supervised practice is still worth doing.
