CA CDL Tanker Vehicles Endorsement Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 CA commercial driver's license manual
- Triple-checked for accuracy
- Updated for July 2025
It’s hard to imagine experiencing the freedom of the open road in a better way than with the opportunities permitted by your California Commercial Driver’s License (CDL). However, if you want to increase your earning potential in the Golden State, you should get a CDL tanker endorsement, which will allow you to carry additional types of cargo. CDL tanker drivers provide essential transportation services to a range of industries, including agriculture and water treatment facilities. These opportunities are just the beginning, and they’re waiting for you to get the training to claim them.
Before obtaining your CDL tanker endorsement, you must demonstrate your knowledge of the road rules and safe driving practices needed to operate these vehicles. Successful applicants must answer 80% of the 20 knowledge test questions correctly to receive a passing score. Passing the knowledge test is your springboard to better job opportunities. You can expand those opportunities even further by getting a Hazardous Materials (HazMat) endorsement ({https://driving-tests.org/california/ca-cdl-hazmat-practice-test/}) that allows you to carry cargo requiring more stringent transportation standards, such as petroleum products and explosives.
Our free California DMV CDL tanker endorsement practice test is expertly designed to help you pass the official knowledge test soon. You’ll find it contains reliable information to rapidly advance your advance your knowledge. The practice test is based on the most recent California DMV CDL manual (California CDL Handbook 2025) and is up to date as of July 2025. The practice test provides more comprehensive instruction than other on-line resources, including study guides. It uses 20 multiple-choice questions, similar to those on the official knowledge test, to assess your current proficiency level. Unlike study guides, the practice test provides you with the information necessary to correct any wrong answers you submit. It allows you to learn at your own pace without worrying about a testing time limit and experience a stress-free learning environment. This approach will equip you with the skills needed to pass the official knowledge test on your first attempt.
