What do yellow road signs typically signify?

1. A warning or caution

2. A speed limit

3. A pedestrian crossing

4. An upcoming stop sign

The correct answer is: A warning or caution

Yellow road signs are primarily used to provide warnings or caution to drivers. This signaling helps alert them to potential hazards or changes in roadway conditions ahead. For example, a yellow sign might indicate a curve in the road, a merging lane, or reduced visibility due to fog or other environmental factors. The color yellow is universally recognized as a sign of caution, ensuring that drivers remain vigilant and prepared to respond to any potential dangers they may encounter on their journey. In contrast, speed limit signs are typically in a white rectangular shape with black lettering, and pedestrian crossing signs usually feature a distinctive symbol or image depicting a pedestrian, often accompanied by the color fluorescent yellow-green. Signs indicating upcoming stop signs can vary in color but do not adhere specifically to the yellow warning standard. Thus, the association of yellow signs with warning and caution is critical for driving safety.
