How Long Does It Take to Get a CDL in Colorado

CDL schools advertise timelines like "get your CDL in 3 weeks." That is technically possible under perfect conditions — but it is not the realistic experience for most people. This guide breaks down every step of the Colorado CDL process, how long each step actually takes, what causes delays, and how your choice of training path changes the total timeline.

Step-by-Step Colorado CDL Timeline

Here is every step in the Colorado CDL process with realistic time estimates for each. The total timeline depends heavily on how quickly you move through each step and whether you encounter any of the common delays described below.

FMCSA does not generally require ELDT theory before obtaining a CLP. Applicable training must instead be completed before a CDL skills test, while the hazardous materials endorsement has its own theory-before-knowledge-test rule. Online ELDT courses from FMCSA-registered providers take most students 1 to 4 days at a reasonable pace. After completion, your provider submits your record to the Training Provider Registry — allow 24 to 72 hours for it to appear. The Colorado DMV verifies your ELDT completion electronically before issuing your CLP. Cost: $50–$150 for online ELDT theory only. Many CDL schools include ELDT theory in their overall program at no additional cost.

You need a current DOT Medical Examiner's Certificate before your DMV appointment. The exam itself takes 30 to 45 minutes. Your certified medical examiner submits results to the FMCSA National Registry by midnight of the next calendar day. Wait 24 to 48 business hours before booking your DMV CLP appointment — the Colorado DMV receives your medical data electronically and cannot process your CLP without it. Find a certified examiner at nationalregistry.fmcsa.dot.gov .

Book your CDL knowledge test appointment at dmv.colorado.gov . DMV wait times in Colorado vary significantly by location and season — from same-week at rural offices to 2 to 3 weeks at busy Denver metro locations. The knowledge tests themselves take 1 to 3 hours depending on how many you are taking. You must pass all required tests in one appointment to receive your CLP that day. If you fail any test, Colorado requires a 1-day waiting period before retaking.

If you pass all required knowledge tests, you receive your CLP the same day at the DMV. Your CLP is valid for one year in Colorado — you have 12 months to complete training and pass the skills test before it expires. As of April 18, 2024, CLPs are not eligible for renewal in Colorado. The CLP must be held for a mandatory minimum of 14 calendar days before you can take the CDL skills test. This waiting period cannot be waived.

Your ELDT behind-the-wheel training must be completed at an FMCSA-registered school. Full-time programs in Colorado run 3 to 5 weeks. You can begin school immediately after receiving your CLP — in fact the 14-day mandatory holding period overlaps with your first two weeks of training, so time is not wasted. Community college programs at Aims and Trinidad State run approximately 3 weeks full-time. Private schools like SAGE run 4 to 5 weeks with 150 hours of total instruction. Weekend programs take 5 to 8 weekends.

The CDL skills test is taken at a Colorado-licensed third-party testing facility — not at the DMV. The test has three parts: vehicle inspection, basic vehicle controls (backing maneuvers), and on-road driving. The entire test takes approximately 90 minutes to 2.5 hours. Scheduling typically requires 1 to 2 weeks advance notice. Schools that are authorized testing sites — such as SAGE and CDL Certifiers — allow students to test on-campus, eliminating separate scheduling delays. If you fail any portion, you must reschedule and pay the test fee again.

After passing the skills test, return to the Colorado DMV with your skills test completion form. Your CDL is issued the same day. The CDL is valid for 5 years. You are now licensed to drive commercial vehicles in Colorado.

The Three Training Paths Compared

Your choice of training path is the single biggest factor in how long it takes to get your Colorado CDL. Here are the three main options with realistic timelines for each.

Quit your current job or take leave and attend school Monday to Friday full-time. Most Colorado private schools run 4 to 5 weeks. Community college programs run 3 weeks but may have a waitlist of 1 to 2 months before you can start. Best for: people who can afford to stop working temporarily and want the fastest realistic timeline.

Attend CDL school on weekends while keeping your current job. Programs run 5 to 8 weekends. Add 1 to 2 weeks for DMV appointments and skills test scheduling. Best for: people who cannot leave their current income but are committed to making the career change.

A major carrier pays for your CDL training and hires you immediately after. The school phase runs 3 to 4 weeks. However you then spend 2 to 3 months as a trainee with a driver trainer before driving solo. Total time to independent employment: 3 to 4 months. Best for: people who want $0 upfront cost and can commit to a 9 to 15 month carrier contract.

The honest comparison: Full-time school is fastest to your CDL but costs $3,500–$7,000 upfront. Company-sponsored training is free but takes longer to reach independent employment due to the trainer phase. Part-time is the slowest but lets you maintain income during training.

What Causes Delays — And How to Avoid Them

These are the most common reasons Colorado CDL applicants take longer than expected. Knowing them in advance lets you plan around them.

The Fastest Possible Colorado CDL Timeline

Under best-case conditions — no delays, first-attempt passes, school with on-site testing — here is the minimum realistic timeline:

The "3 weeks" schools advertise is only possible if you already have your ELDT theory done, your DOT physical complete, your DMV appointment booked, and your CLP in hand before you walk through the school door. The 14-day CLP hold runs concurrently with school — but you need the CLP first. Most students need 1 to 2 weeks of preparation before school even starts.

Tips to Speed Up Your Colorado CDL Timeline

• Start studying now — before doing anything else. Use our free Colorado CDL practice tests to prepare for the knowledge exam before you have even booked a DMV appointment. Passing on the first attempt saves 1 to 2 weeks.
• Book your DMV appointment as early as possible. The DMV calendar fills up. Book your appointment the day you decide to get your CDL — you can always cancel or reschedule if your ELDT or DOT physical is not ready yet.
• Complete ELDT theory online before your DMV appointment. Some CDL schools include ELDT theory as part of their program — but if you can do it independently first, you can walk into the DMV the same week and skip that delay entirely.
• Get your DOT physical done before your DMV appointment. Wait 24 to 48 business hours for results to appear in the FMCSA system. Confirm your record at nationalregistry.fmcsa.dot.gov before your appointment date.
• Choose a school that is also an authorized skills testing site. SAGE and CDL Certifiers can test you on their property. This eliminates 1 to 2 weeks of separate scheduling at a third-party testing facility.
• Start school the day after you get your CLP. The mandatory 14-day CLP hold runs while you are in training — not before it. Every day you wait to enroll after getting your CLP is a day added to your total timeline.
• Apply to community college programs early. Aims Community College has waitlists of 1 to 2 months. Apply the moment you decide to pursue a CDL and use the wait time to get your DOT physical, ELDT theory, and DMV appointment completed.

Frequently Asked Questions

How long does it take to get a CDL in Colorado?

Most Colorado CDL applicants complete the full process in 4 to 12 weeks from start to finish. Full-time CDL school students following a standard program typically finish in 4 to 6 weeks. Students using part-time or weekend programs take 2 to 4 months. The minimum possible timeline is approximately 5 to 6 weeks due to the mandatory 14-day CLP holding period, preparation time, and DMV appointment scheduling.

How long do you have to hold a CLP before the CDL skills test in Colorado?

Colorado requires a minimum 14 calendar day waiting period between receiving your Commercial Learner's Permit and taking the CDL skills test. This is a federal FMCSA requirement and cannot be waived. Use this time in CDL school — the training period and the 14-day hold run simultaneously.

How long is a Colorado CLP valid?

As of April 18, 2024, a Colorado Commercial Learner's Permit is valid for one year and is not eligible for renewal. You must complete your CDL training and pass the skills test within 12 months of receiving your CLP or you will need to restart the process from the knowledge test stage.

Can I get my CDL faster in Colorado than other states?

Colorado has a relatively straightforward CDL process compared to states like California, Texas, and Florida where DMV appointment backlogs routinely run 4 to 8 weeks. Colorado's DMV appointment availability is generally better, especially at suburban and rural offices. Additionally several Colorado schools are authorized third-party testing sites, allowing students to test on campus rather than waiting for a separate state testing appointment.

Does CDL school count toward the 14-day CLP hold?

Yes. The 14-day mandatory CLP holding period runs concurrently with any activity — including CDL school. If you enroll in school the day you get your CLP, by the time you have completed two weeks of training your CLP hold requirement is already satisfied. Do not waste the 14-day window by waiting to start school.

How long after CDL school before I can drive commercially in Colorado?

After passing your skills test, you return to the Colorado DMV the same day or within a few days to have your CDL issued. Once the CDL is in hand you are legally licensed to drive commercial vehicles. For company-sponsored training graduates, most carriers require an additional 2 to 3 months of supervised on-road training with a driver trainer before you drive solo — even with a valid CDL. This is a carrier requirement, not a legal one.
