Which party is primarily responsible for ensuring placards match the ammunition hazard class during transport?

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

Answer: (A)

Placards are a communication tool that must accurately reflect the hazard class of what's being shipped. The shipper is the party responsible for classifying the material and applying the correct placards before transport, ensuring the vehicle shows the proper hazard indication. The driver’s role is to keep those placards in place and visible during transit and to follow safe-transport procedures, but the initial determination and labeling come from the shipper. This distinction helps ensure consistency and regulatory compliance across shipments, especially with ammunition, where the hazard class drives the specific placard used.
