What does a diamond-shaped sign on a vehicle indicate?

• A. The vehicle is a school bus.
• B. The load may be dangerous.
• C. The vehicle is a tractor.
• D. The load is light.

Answer: (B)

Diamond-shaped signs are hazardous materials placards. They warn that the cargo may be dangerous and could pose risks such as fire, toxicity, or chemical hazards. When you see one, give the vehicle extra space, keep a safe following distance, and be prepared for possible leaks or spills. These signs indicate the load is hazardous regardless of the vehicle type or its weight, so they aren’t indicating a school bus, a tractor, or that the load is light.
