What is a placard?

• A. Diamond shaped sign indicating hazardous materials being transported and information for first responders
• B. A printed notice on the dashboard
• C. A sticker on the truck door showing weight
• D. A warning label on the container only

Answer: (A)

A placard is the diamond-shaped hazard sign placed on a vehicle carrying hazardous materials. It’s designed to tell first responders what kind of hazard is being transported and to provide quick identification information, such as the hazard class and identification numbers, so they can respond safely in an incident. This is why it’s the best description: it’s specifically a transport sign used to communicate hazards to anyone handling or responding to a spill or accident. Other options aren’t the same thing. A printed notice on the dashboard isn’t a standardized hazard sign for emergencies. A sticker on the truck door showing weight is about weight, not hazard information. A warning label on the container may exist, but it’s not the placard used on the vehicle to indicate hazards to responders during transport.
