California CDL requirements & eligibility

A complete guide to commercial driver licensing in California — what you need to apply, the fees the California DMV charges, the age and medical rules, and how the testing process actually works.

Who issues CDLs in California?

Commercial Driver’s Licenses in California are issued by the California DMV. California publishes the Commercial Driver Handbook in English, Spanish, and several other languages. The California DMV requires a DL 51 medical examination report and DL 546 medical examination certificate from a certified examiner before issuance. The agency operates under federal Commercial Motor Vehicle Safety Act standards, which means every requirement you read about in the FMCSA CDL Manual applies in California exactly as it does in the other 49 states — with the small set of state-specific procedural details documented on this page.

Age and eligibility

To apply for a CDL in California, you must be at least 18 for intrastate driving (operating only within the state) and 21 for interstate driving (crossing state lines or carrying interstate commerce). You must hold a valid California non-commercial driver’s license at the time of application, present proof of identity and California residency, and supply your Social Security number for verification with the federal Commercial Driver License Information System (CDLIS).

Federal regulations also require that you self-certify your operating category — non-excepted interstate, excepted interstate, non-excepted intrastate, or excepted intrastate — on the application. Non-excepted interstate applicants must additionally provide a current Medical Examiner’s Certificate (MEC, sometimes called a DOT physical card) issued by an examiner listed on the National Registry of Certified Medical Examiners. The MEC must remain current throughout the life of the CDL, and the California DMV will downgrade your CDL to a non-CDL license if it lapses.

Fees

The base CDL issuance fee in California is approximately $92, with additional charges for endorsements, knowledge tests, and skills tests. Hazmat-endorsement applicants additionally pay the federal Transportation Security Administration (TSA) threat-assessment fee — approximately $87 plus state surcharges — before the H endorsement can be added to the license. All fees are subject to change; verify current amounts on the California DMV website at the official California CDL page.

Steps to your California CDL

  1. Read the California CDL handbook from cover to cover. The handbook is free as a PDF on the California DMV website and is the definitive source for every question on the knowledge exam.
  2. Pass the Commercial Learner’s Permit (CLP) knowledge tests. At minimum you take General Knowledge; add Air Brakes, Combination Vehicles, and any endorsement exams you intend to qualify for. Drill our state-specific practice tests until you score consistently above 90%.
  3. Hold the CLP for at least 14 days as required by federal rule before taking any skills test.
  4. Complete Entry-Level Driver Training (ELDT) from a provider listed on the federal Training Provider Registry. ELDT is required for first-time Class A and Class B applicants and for upgrades or new endorsements (Hazmat, Passenger, School Bus).
  5. Pass the skills test (pre-trip inspection, basic vehicle control, on-road driving) administered by the California DMV or a certified third-party tester.
  6. Pay fees and receive your CDL. The California DMV issues the CDL with the appropriate class (A, B, or C) and any endorsements you have qualified for.

Practice tests for California

LicenseReady covers every federal CDL knowledge test in a California-specific framing. Drill the General Knowledge exam first, then move to the endorsement exams that match the work you intend to do. Each test draws from a stable seeded subset of the question bank so you can return and pick up where you left off.
