CDL Tanker Test 2023 Questions and Answers

CDL Tanker Test 2023 Questions and Answers: Try our free CDL Tank Endorsement Practice Test Online. You must pass the CDL Tanker knowledge test for driving a tank vehicle. A “tank vehicle” is used to carry any liquid or liquid gas in a tank of 1,000 gallons or more. (This endorsement is also needed for dry bulk tankers.)

Before loading, unloading, or driving a tanker, inspect the vehicle. This ensures that the vehicle is safe to carry the liquid or gas and is safe to drive. A tank endorsement is also required for Class C vehicles when the vehicle is used to transport hazardous materials in liquid or gas form in the rated tanks.
