California CDL: Steps, Tests and Training Rules

October 7, 2026 · 4 min read

The California DMV issues commercial licenses. California has a few rules that differ from other states, so read this before you book. Rules and fees change, so treat this guide as a starting point and confirm everything on the official site before you go.

Before you apply

Getting the permit

Complete the online CDL application, then visit a DMV office to verify your identity, pay the fee and pass the knowledge tests. You get three attempts per test. Fail the same test three times and your application expires, so you start over.

Training

First-time Class A and B applicants, and anyone adding the passenger, school bus or hazardous materials endorsement, need entry-level driver training. California also requires an extra 15 hours of behind-the-wheel training for an original Class A or B license. Your training provider completes a certification form that you submit before the CDL is issued.

The skills test

Skills tests are by appointment only, and you bring a vehicle for the class you are testing for. The test has three parts: vehicle inspection, basic control skills and a road test. You get three tries, with a retest fee each time.

Plan your timeline. The 14-day wait, the training hours and the appointment all have to fit inside the permit's 180 days.

Rules and fees change. Always confirm the details with the official California DMV or motor vehicle agency before you act. DMVZone practice questions are written to teach the rules and are not copies of the real test.
