Which placard is required for hazmat mixed loads exceeding 1,001 pounds?

• A. Limited Quantity Placard
• B. Dangerous Placard
• C. Special Placard
• D. Non-Flammable Placard

Answer: (B)

When transporting hazardous materials, a warning placard is required to alert others that hazardous substances are on board. If the total quantity of hazmat on the vehicle exceeds 1,001 pounds, the standard requirement is to display the dangerous placard. This general placard covers mixed loads that may involve multiple hazard classes, signaling that special handling and precautions are needed. The limited quantity placard is only used when the entire shipment qualifies as Limited Quantities under the regulations (a stricter, smaller-quantity exception), which isn’t the default for heavier mixed loads. The special placard is reserved for specific, narrow cases, and the non-flammable placard applies only to materials explicitly designated as non-flammable, not to a broad hazmat mix. So for hazmat mixed loads over 1,001 pounds, the dangerous placard is the correct choice.
