What color are warning signs typically?

Warning signs are typically yellow because this color is easily visible and captures a driver's attention. Yellow is used to indicate caution and to alert drivers to potential hazards or changes in road conditions ahead. The bright color stands out against most backgrounds, ensuring that drivers can quickly recognize that they need to reduce speed or be prepared for unexpected situations, such as road work, sharp curves, or pedestrian crossings.

Other colors, like white and blue, serve different purposes on the road. White is generally used for regulatory signs, providing information like speed limits or no parking zones. Red denotes stop signs and other prohibitive directives. Blue signs are used for information related to services such as gas stations or hospitals. Each color serves a distinct function, making it important for drivers to understand their meanings for safety and navigation.
