Road signs that indicate a potential hazard are yellow because this color is universally recognized for warning and caution. Yellow signs alert drivers to proceed with care and to be aware of possible dangers. For example, they may signal curves ahead, pedestrian crossings, or reduced speed limits in certain areas. This color effectively captures attention, helping to ensure that motorcyclists and other road users can recognize potentially dangerous situations in advance, allowing for safer navigation.

Other colors, such as red, generally indicate prohibitions or stop signs; green is primarily used for directional signs; and blue typically indicates motorist services or informational purposes. By understanding the significance of these colors, motorcyclists can enhance their awareness and reaction to roadway conditions, ultimately contributing to safer riding experiences.
