Placards must be placed on how many sides of the vehicle?

• A. Two sides
• B. All four sides
• C. Only front and rear
• D. One side

Answer: (B)

Hazard warnings need to be clearly visible from every angle to alert others and emergency responders quickly. Placards identify the hazardous materials being carried and should be readable whether the vehicle is viewed from the front, rear, or the sides. If a placard were only on two sides, one side could go unnoticed, delaying warning and response in an accident or spill. Displaying placards on all four sides ensures the warning is visible from any direction, which is why four-sided visibility is required.
