To add the Tank endorsement to your CDL license, you will need to pass a written knowledge test that covers topics such as proper loading and unloading procedures, tank vehicle inspection, and safe driving techniques.

If you pass both tests, your CDL license will be updated to include the Tank endorsement. You will not need to apply for a new license, but you may need to pay a fee for the endorsement and provide proof of insurance or other documentation as required by your state's DMV.
