You need to pass a written test, a driving test, and a vision screening, then pay the fee at the DMV

A Class A license in California lets you drive a single vehicle with a gross vehicle weight rating (GVWR) of more than 26,001 pounds, or any combination of vehicles totaling more than 26,001 pounds. You cannot get one without first holding a valid California driver's license for at least one year. The process involves three separate tests — written knowledge, behind-the-wheel driving, and vision — plus medical certification if you drive certain truck types. The whole sequence typically takes several weeks from start to finish, depending on how quickly you schedule your tests and how many attempts you need.

The written test covers California commercial driving rules, vehicle inspection, and safe operation of large trucks. The driving test must be conducted in an actual Class A vehicle, not a regular car. You must pass a vision screening and, for certain endorsements, provide a medical certificate from a licensed physician or optometrist. The total fee for a Class A license is currently $35, plus any costs for testing at a third-party examiner if you choose that route instead of the DMV.

Prerequisites you must meet before testing

California requires you to hold a valid Class C driver's license for a minimum of one year before you can test for a Class A. This means you cannot jump directly from no license to a commercial license. If you have a suspended, revoked, or expired license, you must first restore it to valid status.

You must also be at least 18 years old. If you are under 21, you face additional restrictions on when and where you can drive a Class A vehicle, and you may need a parent or guardian's signature on your process. If you plan to drive a vehicle that requires air brake certification, you must pass an additional air brake knowledge test. If you want to haul hazardous materials, you need a hazmat endorsement, which requires a separate written test and a Transportation Security Administration (TSA) background check.

The written knowledge test and what it covers

The Class A written test has 50 questions, and you must answer at least 40 correctly to pass. You take it at a California Department of Motor Vehicles (DMV) office or at a third-party testing facility. The test covers California Vehicle Code rules specific to commercial driving, pre-trip vehicle inspection procedures, safe operation of large trucks, and hazard recognition.

The test manual, called the California Commercial Driver's License Handbook, is free and available on the DMV website. You can study it online or request a printed copy at any DMV office. Many people study for two to four weeks before testing. You can retake the written test when ready if you fail, but you must wait one day between attempts if you fail twice in a row. You can take the written test in English, Spanish, Mandarin, Cantonese, Vietnamese, or Korean. If you need the test in another language or need an interpreter, contact your local DMV office at least two weeks before your planned test date.

Scheduling and passing the behind-the-wheel driving test

After you pass the written test, you schedule a separate appointment for the behind-the-wheel test. This test must be conducted in a Class A vehicle — you cannot use a regular passenger car. The vehicle must be registered, insured, and in safe operating condition. Many people borrow a truck from an employer or rent one from a commercial vehicle rental company.

The driving test lasts about 45 minutes and includes pre-trip inspection, basic vehicle control (backing, turning, parking), and on-road driving in various traffic conditions. You must demonstrate smooth acceleration, proper braking, safe lane changes, and correct use of mirrors and signals. The examiner is looking for safe judgment and control, not perfection. You can schedule the driving test online through the DMV website, by phone at 1-800-777-0133, or in person at a DMV office. Wait times for driving tests vary by location but often range from two to eight weeks. If you fail, you can retake it, but you must wait two weeks before your next attempt.

Vision screening and medical certification requirements

You must pass a vision screening as part of the Class A licensing process. The DMV will test your vision during your behind-the-wheel appointment. You need corrected or uncorrected vision of at least 20/40 in each eye and a field of vision of at least 70 degrees in each eye. If you wear glasses or contacts, you must wear them during the test.

If you will be driving a vehicle that requires a medical certificate — such as a truck with air brakes or a vehicle carrying hazardous materials — you must obtain a Department of Transportation (DOT) medical certificate from a licensed physician, optometrist, or physician assistant. This certificate confirms you are physically fit to operate a commercial vehicle. The exam covers hearing, blood pressure, diabetes screening, and other health factors. You can find a certified medical examiner through the National Registry of Certified Medical Examiners on the FMCSA website.

Paying the fee and receiving your license

The fee for a Class A driver's license is $35. You pay this at the DMV when you submit your process and pass all required tests. If you use a third-party testing facility instead of the DMV for your written or driving test, that facility may charge an additional fee, typically between $10 and $50 depending on the location and service.

Once you pass all tests and pay the fee, the DMV issues your Class A license on the spot or mails it to you within two weeks, depending on your local office's procedures. Your license is valid for five years from the date of issue. You can renew it by mail, online, or in person before it expires.

Endorsements and restrictions you should know about

A Class A license can carry endorsements that allow you to haul specific cargo or operate specific vehicle types. Common endorsements include H (hazardous materials), N (tank vehicles), P (passenger vehicles), S (school bus), T (double/triple trailers), and X (hazmat and tank combined). Each endorsement requires a separate written test and, in some cases, additional medical certification.

If you are under 21, your Class A license carries restrictions on the hours you can drive and the routes you can take. You cannot drive between 10 p.m. and 5 a.m., and you cannot drive outside California without written permission from your employer. These restrictions lift when you turn 21.

Frequently Asked Questions

Can I take the written test and driving test on the same day?

No. You must pass the written test first, then schedule the driving test as a separate appointment. Most DMV offices require at least a few days between the two tests, though some locations may allow you to schedule them closer together if appointments are available.

What happens if I fail the driving test?

You can retake it after waiting two weeks. There is no limit to how many times you can attempt the test, but you must pay the $35 fee each time you retest. Many people pass on their second or third attempt after additional practice.

Do I need a Class A license to drive a pickup truck or large SUV?

No. A Class A license is only for vehicles with a GVWR over 26,001 pounds. Most pickup trucks and SUVs fall under Class C (regular driver's license). Check your vehicle's registration or door placard to find its GVWR.

Can I get a Class A license if I have a DUI or suspended license?

A current suspension or revocation disqualifies you from testing. You must first restore your driving privileges through the DMV. A past DUI does not automatically disqualify you, but the DMV may deny your process depending on the circumstances and how long ago it occurred.

How long is a Class A license valid?

A Class A license is valid for five years from the date of issue. You can renew it online, by mail, or in person before it expires. Renewal is simpler than the initial test — you typically only need to pass a vision screening and pay the renewal fee.
