According to the Federal Motor Carrier Safety Administration (FMCSA), a Tank vehicle is defined as any commercial motor vehicle that is designed to transport any liquid or gaseous material within a tank that is either permanently or temporarily attached to the vehicle or the chassis. A Hazardous Material (HazMat) is defined as any substance or material that has been determined by the Secretary of Transportation to pose an unreasonable risk to health, safety, and property when transported in commerce.
If you are transporting a hazardous material in a tank vehicle, you will need both a CDL Tank endorsement and a HazMat endorsement. If you are transporting a non-hazardous liquid or gas material that does not require a Tank vehicle to transport, such as milk or water, you may not need a CDL Tank endorsement. However, it's important to check with your state's Department of Motor Vehicles or licensing agency to determine the specific requirements for transporting liquid or gas materials in your state.
To add the Tank endorsement, you will need to:
1. Study for the Tank endorsement knowledge test: You can study for the Tank endorsement knowledge test by reviewing the Maine Commercial Driver License Manual and taking practice tests.
