How to Become a CDL Truck Driver

What the Job Involves Day to Day

Most of a shift is spent driving long distances, sitting in the cab for hours at a stretch (U.S. Bureau of Labor Statistics, 2025). Before you roll, you inspect the trailer — tires, brakes, lights, coupling — and check mechanical, safety and emergency equipment such as the fire extinguisher and reflective triangles (O*NET OnLine, undated). You secure cargo with ropes, blocks, chains or covers, then check load documentation such as the bill of lading for completeness and accuracy.

On the road you follow traffic laws, record working hours in an electronic logging device as federal and state regulations require, and report delays, breakdowns or incidents to a dispatcher. At the end of the run you inspect the trailer again and log any service or repair needed.

The work is outdoor and physical at both ends of the trip: you climb in and out of the cab, crank landing gear, and open doors in rain, heat and snow. Long-haul drivers sleep in a sleeper berth and may be away for days at a time; local and regional routes return home more often.

Path to Becoming a CDL Truck Driver

1. Check age rules (same day). FMCSA requires drivers to be 21 or older to operate a commercial vehicle in interstate commerce or to haul placarded hazardous materials; states may issue a CDL to drivers under 21 for intrastate commerce only (FMCSA, Commercial Motor Vehicle Safety Act of 1986).
2. Pass a DOT physical and get a Medical Examiner's Certificate (1 day, $100 and up). Drivers of interstate vehicles rated over 10,000 pounds must obtain and maintain this certificate and give a copy to the State Driver Licensing Agency (FMCSA, undated; cost example from Guilford Technical Community College, undated).
3. Clear the pre-screening paperwork (1–2 weeks). Budget about $45 for a DOT drug screen, around $20 for a non-certified driving record copy, and $1.25 for an FMCSA Drug & Alcohol Clearinghouse query (Guilford Technical Community College, undated).
4. Pass the written knowledge tests and get your commercial learner's permit (1–2 weeks of study; permit fee $64 in one college's example). Getting a first CDL requires passing a written test, practicing driving, then passing a road test (New York State DMV, undated).
5. Complete ELDT with a registered provider (3–8 weeks). Since February 7, 2022, first-time CDL applicants must complete Entry-Level Driver Training (DC DMV, undated), demonstrating proficiency in both theory and behind-the-wheel instruction under 49 CFR 380, from a provider listed on FMCSA's Training Provider Registry (FMCSA, undated).
6. Pass the CDL skills test (1 day). This covers the pre-trip inspection, basic vehicle control and the on-road drive.
7. Add endorsements if you want them (1–3 weeks). A hazmat (H), passenger (P) or school bus (S) endorsement earned for the first time also triggers the ELDT requirement (DC DMV, undated).
8. Apply to carriers and finish on-the-job training (2–8 weeks). Typical entry-level preparation includes short-term on-the-job training (U.S. Bureau of Labor Statistics, 2025), often riding with a trainer before you are assigned a truck.

Timeline at a Glance

• Weeks 1–2: Book and pass the DOT physical, complete the drug screen, order your driving record and Clearinghouse query, and start studying the state CDL manual.
• Week 2–3: Sit the written knowledge tests and collect your commercial learner's permit (New York State DMV, undated).
• Weeks 3–8: Complete ELDT theory and behind-the-wheel hours with an FMCSA Training Provider Registry provider. Program length commonly runs 4–6 weeks (CostHelper, undated); some run three weeks (DriveBigTrucks citing Truck Driver Institute, 2026) and public certificate programs run 2 months at 222 clock hours (Tennessee College of Applied Technology Northwest via CareerOneStop data, undated).
• Week 4–8: Pass the CDL skills and road test; overall CDL timeline is 3 to 8 weeks (Roehl Transport, undated).
• Months 2–4: Start with a carrier and complete short-term on-the-job training with a trainer (U.S. Bureau of Labor Statistics, 2025).
• Months 4–12: Run solo; add endorsements such as hazmat, which requires being 21 or older (FMCSA, undated).

Requirements Checklist

• Meet the age rule for the work you want: 21+ for interstate driving or placarded hazmat; under 21 is intrastate only where the state allows it (FMCSA, undated).
• Hold a valid Medical Examiner's Certificate and file a copy with your State Driver Licensing Agency (FMCSA, undated).
• Pass a DOT drug screen and have a completed FMCSA Drug & Alcohol Clearinghouse query on file (Guilford Technical Community College, undated).
• Obtain a current copy of your motor vehicle driving record.
• Pass the written knowledge tests and hold a valid commercial learner's permit (New York State DMV, undated).
• Complete ELDT theory and behind-the-wheel instruction with a provider on FMCSA's Training Provider Registry, before the skills test (FMCSA, undated).
• Pass the CDL skills test: pre-trip inspection, basic controls and road drive.
• Have a high school diploma or GED if an employer asks for one; the occupation's education rating is 1 of 4, meaning a diploma/GED or no diploma is usually needed (O*NET OnLine / My Next Move, undated).
