Besides the ordinary vehicle documents, what paperwork does the international ADR standard require to travel with a dangerous-goods consignment?

1. A dangerous goods transport document giving the UN numbers, proper shipping names, hazard classes and packing groups, together with written safety instructions for the crew
2. The consignor's commercial invoice on its own, since it already names the goods
3. Only the carte grise and the driver's licence, as for any other load
4. A copy of the vehicle's technical inspection certificate, which doubles as the hazard declaration
