Here are more resources related to getting your CDL in Colorado:
The CDL Instruction Permit allows you to operate the class of vehicle shown on the permit only when you are accompanied by a person who is at least 21 years of age and holds a valid CDL of the same class of license or higher, with the required endorsements for the vehicle being operated. The person must be in the seat closest to the driver.
This exam indicates an individual is physically qualified to operate a commercial motor vehicle in accordance with 49 CFR 391.41, Subpart E. All commercial motor vehicle drivers must have a physical performed by a medical examiner listed on National Registry of Certified Medical Examiners

You can schedule an appointment online to take the Colorado Commercial Permit test. Go to the Colorado Department of Revenue website and select your county.
Commercial Learner's Permits (CLP) are valid for 180 days, and are eligible for one renewal, which is also valid for 180 days. Please note: The results of the written CDL test are only valid for one year. If the results of your written test are over one year old, you will need to retake the written test, even if your CLP is valid.
The Vets-2-Trucks program helps Colorado residents who are currently serving in the military, close to being discharged or have been recently discharged (within one year) qualify for a Colorado CDL. The Vets-2-Trucks program waives the drive skills testing requirement, but requires individuals to successfully pass the written exams.
