Which of the following signs would indicate a no-passing zone?

A pennant-shaped sign with a yellow background is used to indicate a no-passing zone. This type of sign is typically placed on the left side of the roadway and serves as a warning to drivers that passing other vehicles in that specific area is prohibited, usually due to limited visibility or potential hazards such as curves or intersections. The bright yellow color alerts drivers to exercise caution and adhere to the no-passing rule to ensure their safety as well as the safety of others on the road.

The structure and design of this sign effectively communicate critical information quickly, as it is easily recognizable and distinct from other traffic signs. Understanding the significance of a no-passing zone is essential for maintaining road safety, as disregarding this warning can lead to dangerous situations, particularly in areas where visibility is impaired.
