A commercial driver’s license (CDL) is required for certain commercial motor vehicles under federal and state rules. The appropriate class depends on the vehicle and operation, while endorsements can authorize additional activities or vehicle configurations. Start with the vehicle you expect to drive, not just the job title.

Class and endorsement are different

Class A, B, and C describe broad vehicle categories under applicable rules; they are not beginner, intermediate, and advanced levels. An endorsement may be required for a particular operation, such as transporting hazardous materials, carrying certain passengers, or operating a tank vehicle. Some credentials also carry restrictions based on qualifications or the vehicle used for testing.

Check the sequence before enrolling

Depending on the path, an applicant may need a commercial learner’s permit, knowledge tests, training, and a skills test. Federal Entry-Level Driver Training requirements apply to certain first-time CDL applicants and some upgrades or endorsements, subject to the rules and exceptions. Confirm whether they apply to your situation with the state agency and FMCSA’s official ELDT guidance before paying a provider.

Plan for all costs

Costs may include permit and testing fees, training, a medical examination where required, endorsements, and the final license. Ask providers for an itemized estimate and check the state’s current fee schedule. An advertised course price may not include government fees or retest charges.

Before you start

  1. Identify the vehicle and the work you will do.
  2. Confirm the correct CDL class and any endorsements.
  3. Check eligibility, permit, test, and training requirements.
  4. Verify whether ELDT and medical qualification rules apply.
  5. Compare total costs, schedules, and retest policies.

Use the CDL license guide as a starting point, then confirm the current process with your state’s commercial driver licensing authority and FMCSA.
