Which term describes a principle and procedure of DGR involving restrictions where certain goods require approvals before shipping or can only be transported on certain aircraft?

• A. Classifications
• B. Prohibitions
• C. Declarations
• D. Hidden Hazards

Answer: (B)

Prohibitions describe items that cannot be transported under the DGR, or can only be moved under strict conditions such as requiring approvals before shipping or being limited to certain aircraft. This concept captures the idea of restrictions that demand extra oversight and specific aircraft limitations to manage safety risks. It’s the best fit because it directly addresses the authorization and aircraft limitations mentioned. By contrast, classifications are about hazard groups, declarations cover required documentation, and “hidden hazards” isn’t a formal term used in the DGR.
