What color and shape are warning signs typically?

Warning signs are typically yellow and have a diamond shape. This specific color and shape combination is used because yellow is universally associated with caution, which alerts drivers to potential hazards ahead. The diamond shape is distinctive and easily recognized, helping drivers quickly identify that they need to pay attention to the road conditions or potential dangers, such as sharp curves, pedestrian crossings, or slippery roads. The use of yellow diamond signs is part of a standardized system of traffic signage that ensures consistency and clarity for drivers.
