A yellow diamond-shaped sign indicates a warning of potential hazards ahead. These signs are universally recognized as cautionary signals to alert drivers to various road conditions or situations that may require increased attention or reduced speed. Examples of such warnings include signs for curves, intersections, pedestrian crossings, or animal crossings.

In contrast, the other options do not accurately represent the purpose of yellow diamond signs. Speed limit signs are typically rectangular and display specific speed regulations. Directional signs, which guide drivers to nearby towns or points of interest, are often blue or green and do not have the same warning connotation. Information about lane usage, such as lane control or restrictions, is usually indicated through different shapes and colors, often in a square or rectangular format. Therefore, understanding the function of the yellow diamond sign is crucial for safe driving, as it signifies that drivers should remain vigilant for potential dangers on the road ahead.
