What must be done if hazardous materials are transported without proper hazmat training?

Transporting hazardous materials without proper hazmat training is deemed illegal and poses significant safety risks. Proper training is essential for individuals involved in the transportation of these materials to ensure they understand the regulations, handling procedures, and safety measures necessary to mitigate potential environmental and health hazards. Lack of training can lead to mishandling, spills, accidents, or exposure to harmful substances, which not only endanger the transporters but also the public and the environment. The requirement for proper training is a critical aspect of hazardous materials regulations designed to protect everyone involved.

In this context, the other options do not accurately reflect the seriousness of transporting hazardous materials without proper training. It's vital to acknowledge that compliance with legal training requirements is essential for safe and responsible handling.
