What color is used for warning signs on the road?

Warning signs on the road are designated in yellow to alert drivers to potential hazards or changes in road conditions ahead. The use of yellow is highly visible and helps to quickly catch the attention of drivers, signaling caution as they approach areas that may require slower speeds or increased awareness, such as curves, pedestrian crossings, or construction zones. The brightness of yellow enhances safety, especially in various weather conditions or during nighttime driving. Each color used for road signs serves a specific purpose; for example, red typically indicates stop or prohibitive actions, while green is used for informational signs, and blue often denotes services. By using yellow for warnings, the road safety system provides clear and consistent guidance to drivers.
