Dangerous goods are divided into four categories. Only one of these categories may be acceptable for a non-DG carrier.

Understand the Problem

The question is asking about the categorization of dangerous goods and which category might be acceptable for a non-dangerous goods carrier. It requires understanding the classifications used for dangerous goods.

More Information

Class 9 includes substances that present a danger during transport but do not fit into the definitions of the other classes. It is often considered more flexible for non-specialized carriers.

Tips

A common mistake is assuming all classes are equally restricted for non-DG carriers, but Class 9 allows transportation by some non-specialized carriers.
