If the word FORBIDDEN appears in the hazard class column of an entry in the hazardous materials table, what must a common carrier do?

• A. Transport the material with caution
• B. Never transport the material
• C. Transport with private carrier
• D. Request a special permit

Answer: (B)

When a hazard materials table entry shows FORBIDDEN in the hazard class column, it means the material cannot be transported at all by any carrier. This designation signals a regulatory or safety prohibition, so the proper action is to refuse transport and not offer the material to a common carrier. Instead, you should return it to the shipper or arrange for proper disposal or handling through the appropriate authorities.

This isn’t a situation where you transport with caution, or use a private carrier, or seek a special permit. The FORBIDDEN label overrides those options, indicating that no transport is allowed.
