It takes special skills, training, and aptitude to safely operate large vehicles. We issue commercial driver’s licenses (CDLs) to ensure that drivers meet our high standards for operating commercial motor vehicles.
In California, you may be hired to drive a commercial motor vehicle (CMV) carrying cargo that originates and terminates within state lines if you are at least 18 years old, and to drive for interstate commerce or transport hazardous materials/waste if you’re 21 or older. In either scenario, you need to hold a CDL in order to drive a CMV. What classifies as a CMV?
If you have never had a commercial driver’s license (CDL), or you want to make a classification, endorsement, or restriction change that requires a skills test, you first need to get a CLP and hold it for at least 14 days. Here’s how you apply for a CLP:
- Get a standard California noncommercial Class C driver’s license (DL) (a temporary/interim DL is acceptable).
- Complete an online CDL Application.
- Visit a DMV office, where you will:
- Submit a completed 10 Year History Record Check (DL 939) (if you have been issued a DL of any kind in another state or jurisdiction in the last 10 years).
- Submit a completed Medical Examination Report (MER) Form (MCSA 5875) and Medical Examiner’s Certificate (MEC) (MCSA 5876) (see the “Medical examination report” section below for more information).
- Provide proof of your social security number (SSN). It will be verified with the Social Security Administration while you are in the office.
- Verify your identity with an acceptable identity document. Your current name needs to match the name on the identity document (see the FAQs for more information).
- Present acceptable residency documents (if you have never had a California driver license or identification (DL/ID) card).
- Pay the nonrefundable application fee (application and fee valid for 12 months).
- Have your thumbprint scanned.
- Pass a vision exam.
- Have your photo taken.
- Pass the knowledge test(s). You have three attempts to pass each of the required knowledge tests. If you fail the same test three times, your application is no longer valid and you need to reapply. To allow for sufficient testing time, we do not administer knowledge tests within 30 minutes of closing.
- If you want to apply for a REAL ID, you must also provide proof of your identity, social security number (SSN), and two proofs of residency from the list of acceptable REAL ID documents.
We will issue you a CLP after you pass the knowledge test(s).
If you do not meet all the requirements to get a CDL within 12 months of applying (including passing the knowledge test and skills test), the application will no longer be valid and you must reapply.
Rules and Restrictions
Here are the rules and restrictions for operating a CMV with a CLP:
- You must also obtain and carry a valid California DL.
- The CLP is valid for a maximum of 180 days from the date issued. It can be renewed for an additional 180 days if the expiration date is not more than one year from the initial application date.
- If you present limited term legal presence documents, your CLP may expire on the same date as your legal presence documents.
- A CLP is limited to these endorsements:
- Tank (N)
- Passenger (P)
- School Bus (S)
- You must be accompanied by a California CDL holder while operating a CMV. The license holder must possess the appropriate class of CDL and endorsements to operate the CMV.
- If you have an “N” endorsement, the tanks must be empty when you are driving the CMV. The tank must be purged if it previously contained a hazardous material.
- If you have a “P” or “S” endorsement, you cannot operate a CMV with passengers (other than federal/state auditors and inspectors, test examiners, other trainees, and the accompanying CDL holder).
After you hold a commercial learner’s permit (CLP) for 14 days, you can apply to take the skills test to earn your CDL. This 14 day waiting period also applies to classification upgrades and endorsement/restriction changes that require a skills test.
To apply for a CDL:
- Schedule a skills test appointment (skills tests are not given without an appointment). You may also call 1-800-777-0133 during the regular business hours (8 a.m.-5 p.m. Mon., Tues., Thurs., and Fri., and between 9 a.m.-5 p.m. Wed., excluding holidays) to make an appointment.
- Bring the type of vehicle(s) for the class you want to drive.
- Pass the skills test, which includes a vehicle inspection, basic control skills test, and road test. If you fail any part of the skills test, all other testing will be postponed. You have three tries to pass the skills test. You must pay a retest fee each time you retake the skills test.
Certain applicants may qualify to have the skills test requirement waived:
- If you have a valid CDL from another state that is current or has been expired for less than two years, you can surrender that license (or proof thereof). The license must have equivalent classification, endorsements, and restrictions to the one you are applying for in California.
- You can submit a Certificate of Driving Skill (DL 170 ETP) if your employer is authorized to issue them. Both you and your employer must sign the form.
- If you have military driving experience, you can submit a completed Commercial Military Waiver (DL 965). Learn more about the Troops to Trucks military waiver program.
- If you have a California CLP, and completed CDL training and passed the skills test in another state, you are not required to take the skills test in California. The skills test results will be sent to California DMV from the state where you were tested. You will need to go to a DMV Commercial Driving Test Office to finalize your application. Failing to return to a commercial DMV office may result in your application expiring.
After you pass your skills test, surrender your out-of-state CDL, or submit your certificate, we will issue an interim CDL that’s valid for 60 days. If you have not received your official CDL after 45 days, call us at 1-800-777-0133 to check the status.
