What does a warning sign with a yellow background typically indicate?

A warning sign with a yellow background typically indicates hazards or changes in road conditions. Yellow is used to alert drivers about situations that may require caution, such as sharp curves, pedestrian crossings, or areas where there may be road work. The bright color grabs attention and communicates that the driver should be prepared for potential dangers ahead or changes in the roadway environment. This helps ensure safer driving practices by encouraging drivers to anticipate and react to conditions that could pose risks. It is important for drivers to understand these signs to navigate roads effectively and maintain safety for themselves and others.
