CDL knowledge requirements share a federal framework; state-specific tests and application requirements can differ. What differs by state is the issuing agency, the permit fee, the official manual, and whether you can take your skills test through a third-party examiner instead of only at a state facility. Pick your state below.
States share federal knowledge standards but can have additional requirements. Texas applicants should check the separate commercial-rules requirements and current test-language policy with Texas DPS. This tool does not submit a license application.

Your CDL checklist
The six real steps, in order, from FMCSA's own rules. What you'll pay and where you'll go for each one depends on your state — use the finder above for that.
Get a DOT medical certificate
A physical exam from an FMCSA-certified medical examiner. Required before you can get a learner's permit.
Apply for your Commercial Learner's Permit (CLP)
Pass the knowledge test(s) for your class and any endorsements you need, at your state's licensing agency.
Complete Entry-Level Driver Training (ELDT), if required
Federally required since Feb 2022 for first-time Class A/B applicants and anyone upgrading their license or adding a P, S, or H endorsement. Training must come from a provider listed on FMCSA's Training Provider Registry.
Hold your permit for at least 14 days
Federal minimum waiting period between getting your CLP and taking the skills test.
Pass the skills test
Vehicle inspection, basic control, and road test, in the vehicle class you're applying for.
Get your CDL issued
Your state issues the CDL once your skills test and any required endorsement tests are passed and on file.
