What color are warning signs generally?

Warning signs are generally yellow because yellow is a color that conveys caution and alerts drivers to potential hazards on the road. This standardization helps ensure that drivers can quickly recognize warnings about conditions such as curves, pedestrian crossings, or road work areas. The bright color enhances visibility and draws attention, which is essential for maintaining safety on the roads. The choice of yellow specifically communicates to drivers to slow down and be aware of any dangers that may require their attention, making it an effective choice for signage related to warning messages.
