For a tractor-trailer carrying 975 lbs. of organic peroxides, what placarding is required?

• A. Hazardous materials placard
• B. No placard
• C. Explosive placard
• D. Flammable placard

Answer: (B)

Organic peroxides are classified as hazardous materials but not all quantities require placarding. In this case, the key factor is the quantity being transported, which is 975 lbs. According to the regulations for hazardous materials transportation, specific weight thresholds determine whether a vehicle must display placards.

For organic peroxides, placarding is typically required when the load exceeds 1,000 lbs. Since the amount being transported is 975 lbs, it falls below this threshold, meaning placarding is not required. This regulation helps to balance safety with the practical aspects of transporting hazardous materials. Therefore, since the quantity of organic peroxides being transported does not meet the necessary threshold to mandate placarding, no placard is required for this load.
