Steps to Obtain a California Commercial Driver's License

California's Commercial Driver's License (CDL) program is designed to ensure drivers of large or hazardous vehicles are well-qualified. Whether you're aiming to drive a truck, bus, or transport hazardous materials, the process to obtain a CDL in California is thorough and regulated.

Determine the Type of CDL You Need

California issues three classes of CDLs:

  • Class A: Required for operating a combination of vehicles with a total weight of 26,001 pounds or more, provided the towed vehicle is over 10,000 pounds.
  • Class B: Required for single vehicles over 26,001 pounds, or any such vehicle towing a vehicle not over 10,000 pounds.
  • Class C: For vehicles designed to transport 16 or more passengers (including the driver) or hazardous materials.

Additional endorsements may be required depending on the vehicle and cargo type, such as:

  • Passenger (P)
  • School Bus (S)
  • Tank (N)
  • Hazardous Materials (H)
  • Doubles/Triples (T)

Meet the Eligibility Requirements

To qualify for a CDL in California, you must:

  • Be at least 18 years old for intrastate driving; 21 for interstate or hazardous materials
  • Hold a valid non-commercial California driver’s license
  • Have a clean driving record
  • Provide proof of lawful presence in the U.S.

Complete a CDL Medical Examination

You must pass a medical examination and submit a Medical Examiner’s Certificate (Form MCSA-5876) from a certified medical professional. This ensures you're physically fit to operate a commercial vehicle.

Prepare for and Pass the Written Knowledge Tests

Schedule an appointment at a California DMV office to take the written knowledge tests. These tests cover:

  • General knowledge
  • Air brakes (if applicable)
  • Combination vehicles (Class A only)
  • Any applicable endorsements

Study thoroughly using the California Commercial Driver Handbook. Passing these tests qualifies you for a Commercial Learner's Permit (CLP).

Hold a Commercial Learner's Permit (CLP)

Once issued, the CLP must be held for at least 14 days before taking the skills test. During this time, you can practice driving a commercial vehicle under the supervision of a licensed CDL holder.

The CLP is valid for 180 days and can be renewed once.

Schedule and Pass the CDL Skills Test

The skills test consists of three parts:

  1. Pre-trip inspection
  2. Basic vehicle control
  3. On-road driving test

These tests must be taken in a vehicle that matches the type and class of CDL you are applying for. Schedule your skills test at a DMV office that offers CDL testing.

Submit Fingerprints and Background Check (for Hazmat Endorsement)

If applying for a Hazmat endorsement, you must undergo a TSA background check and fingerprinting process. Start this process online at the TSA Hazmat Endorsement site.

Pay Required Fees

CDL application and testing fees vary by class and endorsements. Visit the California DMV fee page for current information.
