What is the purpose of warning signs?

Answer: C — Tell you there are special conditions or hazards ahead

Warning signs alert you to special conditions or hazards ahead so you can slow down and be prepared to react. They cover things like sharp curves, intersections, merging traffic, construction, or other unusual conditions that require extra caution. They aren’t about parking rules, road type, or the end of a road—that information is conveyed by other sign types. In Nevada, these signs are typically diamond-shaped and yellow with black symbols. When you encounter one, reduce speed as needed and scan ahead for what’s ahead so you can adjust your driving safely.
