What the Course Entails and Exam Details

This guide covers the critical information required by the California DMV for all commercial drivers. The core topics include basic vehicle control, safe driving procedures, transporting cargo safely, and performing essential vehicle inspections.

What to Expect in the Final Exam

The official California DMV CDL General Knowledge exam is a written test consisting of 50 multiple-choice questions. It is not currently offered online and must be taken at a DMV field office.

You must achieve a score of at least 80% (40 correct answers) to pass. While there isn't a strict time limit in the conventional sense, you should allot at least an hour to complete it without rushing. This exam is a closed-book test.

How to Study and Exam Centers

The definitive study resource is the official California Commercial Driver Handbook, which is available at all DMV field offices and online. Read the manual thoroughly, paying close attention to the sections relevant to general knowledge.

Complement your reading by taking this practice test multiple times until you can achieve a passing score consistently. Practice tests are an excellent way to familiarize yourself with the question format and identify areas where you need further review.

Once you are confident in your knowledge, you can schedule your appointment at a nearby DMV field office that handles commercial licensing. You can schedule these appointments online through the official DMV portal.
