How to get a CDL in California?
The process of getting a CDL in California consists of 2 main parts, which are written tests and skills tests. We splitted these parts into pieces as follow:
Take the CDL written knowledge test
Before you go out on the road and take your skills tests, you will have to pass a number of different written tests, depending on the variety of CDL you are seeking to obtain.
General knowledge test
The General Knowledge test is the most crucial step toward getting a CDL in California, regarding vehicle control, traffic laws, safety protocols, and cargo management. You will be answering 50 multiple-choice questions based on your understanding of how to safely operate a commercial vehicle. Preparing with practice tests can also boost your confidence. When you pass, you will be issued your CDL permit and advance to take the skills test.
Endorsement test (if applicable)
Some of the other tests you could be required to take depending on the type of commercial vehicle you will operate, include the Endorsement tests. These tests will determine your working knowledge of specific vehicle types and cargo to include:
- Hazardous Materials
- Passenger Transport
- Doubles/Triples
- School Bus
- Tank Vehicle
Passing these tests will grant you permission to carry special cargo or operate certain vehicles, which may expand your options for working as a commercial driver. Each endorsement has its written test to pass:
Endorsement test | Total questions | Passing score |
Hazardous Materials | 30 | 24 |
Passenger Transport | 20 | 16 |
Doubles/Triples | 20 | 16 |
School Bus | 20 | 16 |
Tank Vehicle | 20 | 16 |
Air brakes test (if applicable)
It is a vital test required by any vehicle operator whose vehicle has air brakes. The test generally consists of 25 multiple choice questions, concerning general knowledge of air brake systems: how they work, and other critical safety elements. Key areas discussed in this section will include the following:
- Air compressor: How it compresses air to give supply to the braking system.
- Air tanks: How to check air pressure in the tanks for appropriate levels and presence of leaks.
- Draining air tanks: Why condensation must be released to avoid damage.
- Brake lag: The driver should realize that air brakes have more delay than hydraulic brakes and drive accordingly.
- Low air pressure warning: Be able to identify warnings-lights and buzzers-that come on when the pressure falls into the danger zone.
- Brake adjustments: Know that periodic brake adjustments are part of regular vehicle maintenance to avert brake failure.
- Emergency brakes: Knowing how the emergency system automatically engages in case the air pressure falls below a certain level.
Combination vehicles test (if applicable)
The combination vehicle test is required to drive vehicles that have trailers attached, such as tractor-trailers. This is the manual to know for safe operation of combination vehicles. A driver needs to pass the combination vehicles test to operate a combination vehicle for more flexibility in commercial driving. The key topics include:
- Coupling and uncoupling: The securing of trailers safely and unsecuring them safely.
- Rollovers: How rollovers can be prevented; primarily on turns.
- Trailer sway: How to effect swaying and off-tracking on curves.
- Brake differences: Understanding how to brake in combination vehicles.

Take the CDL skill test
After you’ve passed your written exams, you’ll need to complete a three-part skills test:
Pre-trip inspection
The Pre-trip inspection is the first part of the CDL skills test, and it is very important to make sure that your vehicle is safe to operate. In this test, you are:
- Show that you can inspect major components of the vehicle for safety; including engine, brakes, tires, lights, mirrors, and safety equipment.
- Describe what you are looking at and what you are checking for, such as wear, leaks, or other damage that would make the vehicle unsafe to operate.
Besides that, it is a very crucial skill for all commercial drivers to acquire, not only to pass the test but also while on the road to avoid accidents.
Basic vehicle control
The basic vehicle control test will:
- Measure your ability to handle a commercial vehicle in controlled, low-speed situations.
- Requires you to drive the vehicle backward, forward through a straight line, and through a defined course, such as cones or lanes.
- You will be scored on the vehicle’s control, accuracy of turns, and ability to not touch obstacles. These basic controls are mastered for safety in complex situations involving parking, loading, or operating in confined spaces.
On-road driving
On-road driving is the final section of the CDL skills test, where you will be required to drive a commercial vehicle on the road amidst traffic. During the test, there will be an examiner present in the vehicle while you drive on public roads who will check whether you observe all the traffic laws, make safe lane changes, and go through intersections. You will be expected to make skills in proper speed, effective use of mirrors, and signaling intent. You cannot get your CDL without successful completion of the on-road driving test.
Receive the actual license
First of all, you will be issued a CDL permit if you succeed in both the written and skills tests. Then comes the last step in acquiring your real CDL license after some driving experience. Make sure that all your paperwork is submitted to the DMV, settle any outstanding fees, and pass any additional screenings.
