If the hazard classification of a transport load changes, who is responsible for ensuring the placards reflect the new classification?

If the hazard classification of a transport load changes, who is responsible for ensuring the placards reflect the new classification?

• A. The driver
• B. The onsite supervisor or NCO
• C. Everyone Involved
• D. The shipper

Answer: (A)

The main idea is that the person in charge of the vehicle during transport must keep the hazard indicators current. Placards are the visible signals that communicate the danger to anyone nearby, including emergency responders, so they must match the actual contents at all times during transit. While the shipper determines the initial classification and the onsite supervisor or NCO can oversee safety, updating the placards as soon as the classification changes is the driver’s responsibility because they control the transport and the vehicle. Saying everyone involved would be too broad, and the driver is the one who must physically reflect the new classification on the vehicle to maintain compliance and safety.
