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 that allows you to carry cargo requiring more stringent transportation standards, such as petroleum products and explosives.
