The acronym DGR in air transport safety refers to which of the following?

• A. Dangerous Goods Regulation
• B. Dangerous Goods Regulation (DGR)
• C. Dangerous Goods Registry
• D. Dangerous Goods Resource

Answer: (B)

The key idea here is understanding what the DGR acronym stands for in air transport safety. DGR is short for Dangerous Goods Regulation, the set of rules that govern how dangerous goods must be classified, packaged, labeled, documented, handled, and trained for when being transported by air. In practice, you’ll often see the IATA Dangerous Goods Regulations cited as the international standard used by airlines, shippers, and regulators, and the acronym DGR is derived directly from that formal title. That exact phrasing with the acronym in parentheses matches what the term represents, making it the best choice.

The other options drift away from the established regulatory title. Registry and Resource imply different kinds of references or tools, not the binding rules that dictate how dangerous goods are safely carried by air. So the correct interpretation is the regulation that sets the required procedures and standards for safe air transportation of dangerous goods.
