For a shipment described as organic peroxides, other than Type B, a tractor-trailer carrying 975 pounds requires which placard?

• A. Flammable placard
• B. No placard
• C. Explosive placard
• D. Corrosive placard

Answer: (B)

Placard requirements on highways depend on both the hazard class and the total quantity on the vehicle. Organic peroxides are Class 5.2 materials, and for shipments that are not Type B, a placard is required only if the total amount on the vehicle reaches or exceeds 1,001 pounds. Since the tractor-trailer is carrying 975 pounds, it does not meet that threshold, so no placard is required. If the quantity were 1,001 pounds or more, a placard indicating the organic peroxide hazard would be needed.
