Which statement about placards and shipping papers is correct?

• A. Statement 1 is false; statements 2 and 3 are true.
• B. All three statements are true.
• C. Statements 1 and 3 are true; statement 2 is false.
• D. Statements 1 and 2 are false; statement 3 is true.

Answer: (A)

Placards and shipping papers each serve a different purpose in hazmat transport. Placards are the external warning signs on a vehicle that alert responders and the public to the presence and type of hazard. Shipping papers, on the other hand, carry the detailed information about the hazardous material—its proper shipping name, hazard class, ID number, packing group, quantity, and emergency contact—and must be carried with the shipment and be accessible to responders.

The option you chose says the first statement about placards is false, while the second and third statements are true. That fits real-world rules because placards are not always required; there are exemptions (such as for small quantities or certain excepted or limited quantities). Shipping papers are generally required to accompany hazardous materials in transport and must be available to the driver and responders. The information on the shipping papers is what responders use to identify the material and know how to handle it, while placards provide a quick, high-level warning.

So the correct choice aligns with the idea that placard requirements have legitimate exceptions, whereas shipping papers are consistently required and provide the essential, detailed hazard information. If you had the exact text of the statements, you’d likely see the first claim about placards being universally required as the inaccurate one, with the other two reflecting the standard roles of shipping papers and the conditional nature of placards.
