Why this is the answer

The SHIPPER'S CERTIFICATION on hazmat shipping papers is a signed statement by the shipper certifying that the hazardous materials have been properly CLASSIFIED, DESCRIBED, PACKAGED, MARKED, and LABELED, and are in proper CONDITION for transport according to all applicable regulations. CDL hazmat. This places responsibility on the SHIPPER for correctly preparing the shipment. The DRIVER/carrier, however, still has responsibilities: to refuse leaking or improperly prepared shipments, ensure correct placarding, keep papers accessible, and transport safely. The certification creates a documented chain of responsibility. Knowing the shipper's certification (certifies proper preparation per regulations) is commonly tested hazmat documentation knowledge.
