What does a yellow traffic sign indicate?

A yellow traffic sign indicates a special situation or hazard, alerting drivers to potential dangers or changes in conditions ahead. These signs are an important part of road safety as they help to prepare drivers for unexpected situations, such as curves in the road, pedestrian crossings, or areas where the road may be slippery. For instance, a curve sign warns that the road will soon change direction, which is crucial information for safe navigation.

While there are specific colors for certain types of signs, such as orange for construction warnings and white for speed limits, yellow is universally used to communicate caution. This is fundamental for ensuring that drivers remain vigilant and can make informed decisions to follow safe driving practices.
