The steps
- Get a DOT medical card. A commercial driver must pass a physical with a medical examiner listed on FMCSA’s National Registry (49 CFR 391.41, 391.43); the certificate lasts up to 24 months.
- Pass the knowledge test and get a commercial learner’s permit (CLP). The CLP lets you practise with a qualified CDL holder beside you and is valid for no more than a year (49 CFR 383.25).
- Hold the CLP for at least 14 days before taking the skills test (383.25(e)).
- Complete entry-level driver training with a provider on FMCSA’s Training Provider Registry, if this is your first Class A or B CDL, an upgrade, or a first passenger, school bus or HazMat endorsement (49 CFR 380.609). 64 registered providers have a training location in Colorado, 62 of them offering behind-the-wheel training.
- Take the skills test: vehicle inspection, basic control skills and an on-road test, in a vehicle of the class you want (49 CFR 383.113). Colorado names 60 places as CDL skills test sites.
- Age. Driving across state lines requires being at least 21 (49 CFR 391.11(b)(1)); a state may license drivers from 18 for driving inside the state only.
