If FORBIDDEN appears in the hazard class field, which entity is prohibited from transporting the material?

• A. A common carrier
• B. A private carrier
• C. An airline
• D. A rail carrier

Answer: (A)

FORBIDDEN in the hazard class field means this material cannot be offered for transport by a common carrier. A common carrier is a service that moves goods for the public for hire, so the prohibition stops any public transport option from moving the material. A private carrier, owned or controlled by the shipper, may still transport it under the shipper’s control. The idea is to prevent use of public transport services, while private transport remains the option if allowed.
