Which category of hazardous goods requires paperwork to be kept in the vehicle with the owner's signature and the name of the authorized driver?

• A. Gases
• B. Explosives
• C. Flammable liquids
• D. Radioactive materials

Answer: (B)

Explosives have the strictest controls among hazardous goods, so the documentation for them is kept with the shipment and carries clear accountability. The dangerous goods transport document for explosives must stay in the vehicle and include the owner’s signature and the name of the authorized driver. This setup provides an immediate, verifiable record of who declared the goods, who authorized the transport, and who is actually operating the vehicle. It helps inspectors quickly confirm compliance and trace responsibility if anything goes wrong. Other classes require shipping documents too, but the explicit requirement to keep the paperwork in the vehicle with the owner’s signature and the driver’s name is a specific, heightened precaution tied to transporting explosives.
