  5. 5Pass the General Knowledge test plus any Air Brakes, Combination or endorsement tests, then pay $20 for your CLP.
  6. 6Finish federal Entry-Level Driver Training (ELDT) with a school on FMCSA's Training Provider Registry before you take the skills test.

What to bring

  • Your valid Colorado driver license
  • Proof of lawful presence, such as a U.S. passport, birth certificate or green card
  • Your Social Security number
  • Two proofs of your Colorado address

Medical card

Colorado does not let you self-certify your medical status; your medical examiner sends results to the national registry. You still declare your type of driving when you apply, and your medical card must be on file first.

Good to know in Colorado

  • Your CLP cannot be renewed, and your written test results count for only one CLP.
  • Your skills test completion form must be dated within 60 days when you trade your permit for a CDL.
  • You must be 21 for a Hazmat endorsement.
  • Colorado raised its CDL fee to $35 on June 30, 2026.

Non-domiciled applicants

Colorado paused issuing and renewing non-domiciled CDLs and CLPs on September 29, 2025. Under federal rules since March 16, 2026, asylum seekers, refugees and DACA recipients are not eligible.

Confirm with DMV before you go

We couldn't confirm these from official sources, so we left them out rather than guess:

  • How long you must wait to retest after failing.
  • The vision standard for a CDL.
  • Whether you need a REAL ID.
  • What third-party testers usually charge for the skills test.
Federal rules that apply in every state(show)
Age
You can get a CLP at 18, but until you turn 21 you can only drive a commercial vehicle inside your own state. Hauling hazmat requires you to be 21.
Knowledge tests
Everyone takes General Knowledge. Class A adds Combination Vehicles, and anyone driving a truck with air brakes takes Air Brakes. You need at least 80% on each test.
14-day wait
You must hold your CLP for at least 14 days before you can take the skills (road) test. Some states make you wait longer.
Driving on a CLP
A CDL holder with the right class and endorsements must sit in the front seat whenever you drive. Hazmat is never allowed on a CLP. With a passenger or school bus permit you can't carry passengers, and with a tank permit the tank must be empty.
Entry-Level Driver Training
You must finish ELDT with a provider on FMCSA's Training Provider Registry before your Class A or B skills test. You do not need it to get the permit itself.
Medical card
You self-certify the kind of driving you will do. Most new drivers are 'non-excepted interstate' and need a DOT physical from a certified medical examiner, who now sends the results to your state electronically.
Clearinghouse check
Before issuing a CLP, your state checks FMCSA's Drug & Alcohol Clearinghouse. A 'prohibited' status blocks the permit until return-to-duty is complete.
