The correct answer is identified as HAZMAT and Tanker because these two endorsements are essential for commercial drivers who wish to transport certain types of cargo.

A HAZMAT endorsement is required for drivers transporting hazardous materials, ensuring that they understand the special handling, safety protocols, and regulatory requirements for these dangerous goods. This endorsement is crucial for maintaining safety on the roads, as hazardous materials can pose significant risks to public safety and the environment.

A Tanker endorsement, on the other hand, is necessary for drivers who operate vehicles designed to transport liquid cargo in tank-like compartments. Tanker vehicles require specific driving skills due to the unique handling characteristics of liquid cargo, especially when it comes to controlling the vehicle's balance during acceleration, braking, and turning.

Both endorsements help ensure that drivers are adequately trained for the responsibilities involved in hauling specific types of cargo, promoting safety for both the driver and the public.
