Which color of warning sign is used to indicate general warning?

The use of yellow as the color for warning signs is a fundamental aspect of road signage that conveys important information to drivers. Yellow is universally recognized as a signal of caution, alerting motorists to potential hazards or changes in road conditions ahead. This color is associated with warnings about conditions that require increased attention, such as curves, intersections, or temporary roadwork.

By establishing a standard where yellow represents general warnings, it ensures consistency and helps drivers quickly recognize the need to be vigilant while navigating the road. The significance of the other colors in road signage varies; for instance, red often indicates stop or prohibition, while fluorescent yellow-green is used for pedestrian crossings and school zones, and blue provides information about services and amenities. Therefore, understanding the primary function of yellow in warning signage enhances safety on the roads, making it essential knowledge for anyone involved in traffic control and safety.
