California CDL Test Questions 2026
Question counts, passing scores, the 3-attempt limit, what each test covers, and why the CA handbook differs from generic study materials.
California CDL Exam Guide 2026 — Everything You Need to Know
The California CDL is issued by the California Department of Motor Vehicles (CA DMV). The official study resource is the California Commercial Driver Handbook, available free at dmv.ca.gov. All CDL knowledge exam questions come from this handbook. Tests are taken on a computer at a California DMV field office and are multiple-choice.
May 2026 Update: On May 18, 2026, California DMV launched programming to implement the federal NRII (National Registry II) electronic medical certification requirements. Shortly after launch, DMV identified technical issues and made the decision to roll back the change. As a result, some Medical Examination Reports and Certificates expected to transmit electronically around that date may not have reached DMV. If you had a physical around May 18, 2026 and expected electronic submission, bring a paper copy of your certificate to your appointment. Contact your local DMV field office to confirm the current procedure, since DMV continues working to resolve the issue.
What Makes California CDL Testing Unique
California has several requirements that differ from other states. Understanding these before your DMV appointment prevents costly surprises:
- 15-hour behind-the-wheel minimum (California law) — California Vehicle Code §15250.1(b) requires Class A and B applicants to complete at least 15 hours of behind-the-wheel training. Your certified provider must complete Form DL 1236 and submit it to a DMV field office before your CDL can be issued. This is in addition to federal ELDT requirements.
- Full retesting required for out-of-state CDL transfers — Unlike most other states, California requires applicants transferring a CDL from another state to pass all required California knowledge tests and the CDL skills test from scratch. Your out-of-state test results do not transfer.
- 3-attempt maximum on every knowledge test — Fail any knowledge test 3 times and your application is voided. You must reapply from the beginning and pay all fees again. Study thoroughly before your first attempt.
- ETP-only third-party testing — California’s Employer Testing Program (ETP) allows qualifying employers to test their own employees. Unlike Texas (TPST), CDL schools generally cannot administer the skills test. Most applicants test at a DMV-designated skills testing location — which may not be the same office as your knowledge test.
- 35 languages available for testing — California offers CDL knowledge tests in up to 35 languages including Spanish, Chinese, Korean, Vietnamese, and Tagalog. Contact your local DMV field office to confirm language availability.
- Skills test offices are not always the same as knowledge test offices — In California, CDL skills tests are conducted at select DMV field offices designated for skills testing. Always confirm which services a specific DMV office provides before booking.
California CDL Application Process — Step by Step
- Hold a valid California Class C driver license — Transfer any out-of-state license to California before applying for a CDL.
- Study the California Commercial Driver Handbook — Download it free at dmv.ca.gov. Read it before starting practice tests — understanding concepts beats memorizing answers.
- Complete a DOT physical examination — Get a DOT physical from a certified FMCSA medical examiner. Confirm the current submission procedure with your DMV office, since a technical issue caused California DMV to roll back its NRII electronic submission system on May 18, 2026.
- Visit a California DMV office and apply — Complete the application, pay the $100 fee (covers CLP, up to 3 knowledge test attempts, and first skills test), pass the vision exam, and take all required knowledge tests.
- Hold your CLP for at least 14 days — Federal law requires a minimum 14-calendar-day hold before the skills test. Use this time to complete your ELDT and BTW training.
- Complete ELDT and 15-hour BTW training — First-time Class A and B applicants must complete ELDT at an FMCSA-registered provider AND meet California’s 15-hour BTW minimum. Your provider completes Form DL 1236 and submits it to the DMV.
- Schedule and pass the CDL skills test — Three parts: pre-trip vehicle inspection, basic vehicle control, and on-road driving. You must provide your own commercial vehicle.
