What types of cargo require special handling?

Special handling is necessary for hazardous materials, oversized loads, and livestock due to the inherent risks and specific regulations surrounding these types of cargo. Hazardous materials can pose significant health risks and environmental dangers if not handled, transported, or stored correctly. Therefore, there are strict regulations and training requirements specific to transporting these types of materials to ensure safety.

Oversized loads can exceed road regulations regarding dimensions and weight, requiring special permits and sometimes specific routes, escorts, or signage to ensure safe transport. This is crucial for the safety of the driver, other road users, and property.

Lastly, livestock transportation involves additional considerations such as the welfare of the animals, securing them properly during transit, and ensuring they have enough ventilation, food, and water. There are also regulations regarding the duration of travel without rest for the animals to minimize stress and prevent injury.

The other options involve various cargo types, but they do not carry the same level of risk or legal requirement for special handling as the materials mentioned in the correct choice.
