Answer: (C)

A vehicle transporting over 1001 pounds of corrosive materials must carry a placard that is white over black. The white background indicates the nature of the hazard, in this case, corrosives, which can include substances that may harm the skin or damage exam equipment or materials through chemical action. The black designation provides a clear and recognizable visual cue for drivers and emergency responders, highlighting the potential danger associated with these materials. Proper use of this color combination facilitates quick identification and appropriate responses in the event of an incident involving these hazardous materials. Understanding placarding is vital for ensuring safety regulations are followed during the transport of hazardous substances.
