What color are warning signs typically?

Warning signs are typically yellow or orange because these colors are highly visible and draw attention, which is crucial for alerting drivers to potential hazards or changes in road conditions. The use of yellow indicates caution and is common for signs that indicate general warnings, such as curves, intersections, and pedestrian crossings. Orange is specifically used for construction and maintenance-related warnings, signaling drivers to slow down and remain alert in areas where work is being conducted.

Using these colors for warning signs helps ensure that they stand out in various environments and conditions, maximizing the safety of all road users by conveying important information effectively. Other colors like blue and green typically represent informative guidance or regulatory signs, while red is primarily reserved for stop signs, yield signs, and other critical notices, making them unsuitable for warnings.
