Which items are part of the information needed to determine the correct placards?

• A. The material's hazards class, the amount of hazardous materials, and the type of shipment
• B. The shipping route, driver license, and vehicle color
• C. The packaging material, temperature, and age
• D. The destination city's population

Answer: (A)

Placards are determined by three things: the material's hazards class, the amount being shipped, and the type of shipment. The hazards class tells you what kind of danger the cargo presents and which placard symbol to display. The amount matters because there are thresholds that determine whether a placard is required at all and which type of placard applies. The type of shipment helps clarify regulatory nuances—for example, whether the cargo is a standard hazardous material or a special category like hazardous waste, which can affect which placards or exemptions apply. Other factors such as the shipping route, driver's license, vehicle color, packaging material, temperature, age, or destination population do not determine placard requirements.
