How to Get Your CDL: A Step-by-Step Beginner's Guide

You generally need to be at least 18 for intrastate driving (21 for interstate/crossing state lines), hold a valid regular driver's license, and pass a DOT physical exam confirming you're medically fit to drive commercially.

Before training, you'll need a Commercial Learner's Permit — this involves passing a written knowledge test covering general trucking knowledge, air brakes, and whichever vehicle class/endorsements you're pursuing. Most states require holding the permit for a minimum period (often 14 days) before you can take the final skills test.

This is where you'll choose between a company-sponsored program (free, with a work commitment) or an independent school (paid tuition, no commitment) — see our comparison of both for the full trade-offs. Training covers both classroom instruction and behind-the-wheel practice, typically over a few weeks.

The skills test has three parts: a pre-trip vehicle inspection (proving you can identify safety issues before driving), basic vehicle control maneuvers, and an on-road driving test. Passing all three gets you your CDL.

Once licensed, pay varies enormously by company — the gap between the lowest and highest fresh-start pay among carriers we track is tens of thousands of dollars a year. This is exactly the decision worth spending real time on before signing anywhere.
