Which documents must the transport unit carry, and produce to IAAA inspectors, on a fully regulated ADR journey (Ordinance No. 40 Art. 43)?

1. Only the vehicle registration card, because ADR is self-declared
2. Only a fuel receipt and a tachograph printout
3. The ADR transport document, written instructions, and photo identification for each crew member, plus the driver certificate and vehicle approval when ADR requires them
4. A municipal parking permit instead of written instructions
