If you are under 18 when you apply for a Colorado driver license, you must submit a signed log of at least 50 hours of supervised driving, 10 of them at night. Someone must also have signed the Affidavit of Liability and Guardianship when you got your permit. This checklist covers both forms, who can supervise, and the mistakes that get a log rejected.
Colorado driving log checklist
- At least 50 hours total, with at least 10 at night.
- 62 hours total if you are using the 30-mile exemption instead of 6 hours of driving school training.
- Logged on the Drive Time Log Sheet (DR 2324) or in the RoadReady app. Either way, print it.
- Your name clearly legible at the top.
- Totals entered for day driving time, night driving time and grand total.
- Signed and dated by a parent, guardian or other responsible adult.
- Uploaded for an online upgrade, or brought to an in-person license appointment.
The DMV says it will not accept a license application without the totals and the signature.
How to fill in the Drive Time Log Sheet (DR 2324)
- After each drive, record the date, the verifier’s initials, the day driving time, the night driving time and the running grand total.
- The comments column is optional, but useful for noting skills you practiced.
- Photocopy blank pages if you need more rows.
- Once you reach the totals, check your math. Then enter total day time, total night time (at least 10) and grand total (at least 50) in the boxes on page 1.
- Have your parent, guardian or responsible adult sign and date the certification.
The 50 hours may include your 6 hours of behind-the-wheel training with a driver education provider, if you took it. The 12 exemption hours are in addition to the 50.
Who can supervise your Colorado practice driving?
- Every supervisor must be 21 or older, sit in the front passenger seat, and hold a valid Colorado license (or military ID with a valid out-of-state license).
- CDOT says logged hours are supervised by the Colorado-licensed parent or legal guardian who signed the Affidavit of Liability, or by a Colorado-licensed alternate permit supervisor they appoint.
- A permit holder under 18 driving without an approved supervisor faces a minimum $70 fine and 3 points (CDOT).
Alternate permit supervisor
If the parent or guardian signing the affidavit does not hold a valid Colorado license, they can appoint an alternate permit supervisor on the DR 2460. The alternate signs to confirm they hold a valid Colorado license and are at least 21, and gives their Colorado customer identification (license) number.
The Affidavit of Liability and Guardianship (DR 2460)
Every permit applicant under 18 needs one. By signing, the adult:
- accepts liability for the minor’s driving, including financial responsibility for any crash the minor causes
- agrees to go with the minor to any hearing about their permit or license
- confirms they are 21 or older and hold a valid Colorado license, or a valid out-of-state license with military ID, or are appointing an alternate supervisor
Who can sign
The handbook lists a parent, stepparent, grandparent with power of attorney, legal guardian, spouse older than 18, or any other responsible adult willing to accept legal liability. The DMV adds that the signer must be over 21.
How it is signed
- In front of a driver license office employee at your appointment, with the signer showing their license, or
- In advance in front of a notary public. Forms signed at home without a notary are not accepted.
Withdrawing a signature
The signer can withdraw at any time using form DR 2464 at a driver license office. The minor’s permit or license is then canceled. A new signer must complete a new DR 2460 in person, and a new permit is issued for a fee. Minors in foster care can be exempt if certain conditions are met.
When you do not need a log
- You are 18 or older when you apply for the license.
- You will turn 18 before you have held the permit for a year.
Moving to Colorado mid-log
Hours logged in your previous state count toward the 50. Time held on an out-of-state permit also counts toward the 12-month holding period. If you are under 21, apply for a Colorado permit within 30 days of moving.
Common questions
Can my grandparent supervise my Colorado practice hours?
Your hours must be supervised by the person who signed the affidavit or by an appointed alternate permit supervisor (CDOT). A grandparent can be either, if they are 21 or older with a valid Colorado license.
Does driving school time count toward the 50 hours?
Yes. The 6 hours of behind-the-wheel training with a driver education provider may be included.
What counts as night driving?
The DR 2324 does not define it. Colorado requires headlights from sunset to sunrise, so log night hours after sunset.
Can I use an app instead of the paper log?
Yes, the RoadReady app is accepted, but you must print its log sheet for the license appointment.
My parent cannot come to my permit appointment. What now?
Bring a DR 2460 signed in front of a notary.
What happens if the person who signed withdraws?
Your permit or license is canceled until a new adult signs a new affidavit in person.
