What is the purpose of placards in ammunition transportation?

• A. Weight limits
• B. The shipping route is shown on placards
• C. Temperature range
• D. Hazardous signs and symbols

Answer: (D)

Placards are there to communicate hazards visually during transport. For ammunition, they carry the signs that indicate explosives and the related hazard class, often with additional identifiers such as a UN number. This quick visual information lets everyone involved—drivers, inspectors, and emergency responders—immediately recognize the level of danger and follow the correct safety and emergency procedures. Weight limits come from packaging and regulatory rules, not the placards. The route is shown on routing documents and maps, not on placards. Temperature range is specified elsewhere on labels or shipping papers, but placards exist specifically to convey hazard information.
