*The ADR primarily states that- with the exception of certain exceptionally dangerous materials-- hazardous materials may in general be transported internationally in wheeled vehicles, provided that conditions are met for regulating:
- Packaging and labels.
- The construction, equipment, and use of transport vehicles. Each hazardous material entry has a unique 4-digit UN Number.
