Colorado CDL License FAQs in 2024

What are the requirements for a CDL license?

To get a CDL license in Colorado, you need to obtain a commercial learner's permit (CLP) by passing knowledge tests. Hold the CLP for at least 14 days before taking the skills test. You also need to meet age, medical, and residency requirements. CDL training, while not mandatory, is highly recommended.

What is the cost of getting a CDL?

The cost for a CDL in Colorado includes a $16.80 fee for the CLP and varying fees for the skills test, typically around $275. The CDL license fee is $35. Additional costs for medical exams and training programs vary.

What disqualifies you from getting a CDL?

In Colorado, disqualifications include major traffic offenses like DUIs or reckless driving, criminal convictions involving motor vehicles, and failing the medical examination required for CDL holders.

How long does it take to get a CDL?

The time to get a CDL in Colorado varies. After holding a CLP for 14 days, the duration depends on your readiness and the length of any CDL training program you choose to enroll in.

How many times can you fail the CDL test?

In Colorado, you can retake the CDL test if you fail, but after two failed attempts, additional fees will be required for subsequent tests. There is no set limit on the number of retakes.
