When state variations to DGR are most restrictive they:

• A. apply globally
• B. apply in the territory of the state and to operators of that state
• C. apply to importers only
• D. apply to passenger carriers

Answer: (B)

State variations to the Dangerous Goods Regulations are national tweaks to the IATA DGR. The most restrictive form is when these variations apply in the state’s territory and to operators of that state, because that scope covers both the geographic area and the entities under the state's jurisdiction. In practice, this means any air transport activities within that state and carriers registered or based there must comply, making it the tightest level of safety regulation. They aren’t global, and they aren’t limited to importers or only passenger carriers—the variations can affect many parties involved in operations within that state.
