Placards must appear on which sides of the packaging?

• A. All four sides
• B. Two sides
• C. Three sides
• D. Only the front side

Answer: (A)

Placing placards to warn about hazardous materials must be visible from every approach to the vehicle or package. This is because quick, universal recognition of the hazard from any direction helps responders and other handlers assess risk and take appropriate actions during transport. By posting placards on all four sides, the warning isn’t blocked or hidden if one side isn’t visible—front, back, and both sides are covered, ensuring the hazard information is always accessible. Putting placards on only two sides, three sides, or just the front could leave a view from another direction without warning, which defeats the purpose of clear hazard communication.
