How to Become a Truck Driver in the US in 2026: A Step-by-Step Guide

You can hold a commercial license at 18, but only for driving inside your own state. Driving across state lines requires you to be 21 or older.

You also need a valid regular driver's license and must be able to read and speak English well enough for road signs and roadside inspections. Since June 2025, failing that check can put a driver out of service on the spot.

Most employers also expect a high school diploma or equivalent, and many set their own standards above the federal minimum.

A Class A CDL covers tractor-trailers, the classic 18-wheeler. Class B covers heavy single vehicles like dump trucks and box trucks, and Class C covers smaller vehicles carrying passengers or placarded hazardous materials. Most long-haul and regional jobs require Class A.

If you are unsure, Class A keeps the most doors open, because it also lets you drive Class B and C vehicles.

Before you can get a learner's permit, you need a DOT medical exam from an examiner listed on FMCSA's National Registry. A regular doctor's checkup does not count unless that doctor is on the registry.

The exam checks vision, hearing, blood pressure and general health. A passing result gives you a medical certificate valid for up to 24 months, or less if a condition needs monitoring.

The CLP comes after you pass the written knowledge tests at your state licensing office. It lets you practice in a truck on public roads with a qualified CDL holder beside you.

You must hold the permit for at least 14 days before taking the skills test. A CLP can be valid for up to one year from the date it is first issued.

Check your state's testing language rules early. Texas, for example, has given CDL and CLP knowledge tests in English only, with no interpreters, since June 1, 2026.

Since February 7, 2022, first-time Class A and Class B applicants must complete federal ELDT from a provider listed on FMCSA's Training Provider Registry before taking the skills test.

ELDT has a theory part, where you must score at least 80 percent, and a behind-the-wheel part on a range and public roads. Your instructor decides when you are proficient; there is no federal minimum number of hours.

The skills test has three parts: a pre-trip vehicle inspection, basic control skills such as backing, and an on-road driving test. You can schedule it only after your training provider has reported your ELDT completion.

Most new drivers spend several weeks driving with an experienced mentor after they are hired. This period teaches the specific truck, freight and company procedures.

Your first job matters more than its first paycheck. A clean first year builds the safety record that opens better-paying and more home-time-friendly jobs later.

Private truck driving schools and community college programs typically run from a few weeks to several months. BLS describes programs lasting up to 3 to 6 months, while many private schools finish in 3 to 6 weeks.

• You need to be 21 to drive across state lines; 18-year-olds can drive only within their state.

• Get the DOT physical first, then the learner's permit, then federally registered training.

• Choose a school from FMCSA's Training Provider Registry, or your training will not count.

• English proficiency is now enforced at roadside inspections, and some states test in English only.

• Treat your first year as the foundation of your safety record.

Requirements vary by state. Confirm details with your state licensing agency and FMCSA before you enroll.
