Yellow signs are typically used for what purpose?

Yellow signs are predominantly used to warn drivers of potential hazards or changes in road conditions ahead. This color is chosen because it grabs attention and is easily visible, allowing drivers to prepare for upcoming situations that may require caution. Common examples of yellow warning signs include those indicating curves, pedestrian crossings, or road work zones, all aimed at enhancing safety by alerting drivers to possible dangers.

The other options involve different signage colors and purposes. For instance, stop signs are typically red, speed limit signs are often white with black text, and signs indicating favorable road conditions usually employ green. Each color serves its distinct function within traffic management, with yellow specifically reserved for warnings to enhance driver awareness and safety.
