In the DGR Table, an alphanumeric indicator (a letter followed by digits) relates to which set of special provisions described in Subsection 4.4?

• A. Column G - Passenger and Cargo Aircraft Limited Quantity
• B. Column N - ERG Code
• C. Column M - Special Provisions
• D. Column K - Cargo Aircraft Only

Answer: (C)

An alphanumeric indicator in the DGR Table is a code that points you to Special Provisions. These provisions are listed and defined in Subsection 4.4, and they tailor or modify the standard rules for specific dangerous goods. When you see such a code, you consult Subsection 4.4 to understand the exact packing, labeling, quantity, or handling exceptions that apply to that substance. That’s why this indicator corresponds to the set described as Special Provisions. The other items in the table refer to different concepts—ERG Code is for emergency response guidance, while the others describe aircraft-related restrictions—not the special provisions that modify the general requirements.
