Which color on a traffic sign is used to convey information?

The use of blue on traffic signs is specifically designed to convey information regarding facilities and services. Blue signs typically indicate points of interest such as hospitals, gas stations, and rest areas, providing vital information to drivers about available services along the roadway. This color is universally recognized and helps guide motorists to essential amenities, enhancing their travel experience.

Other colors on traffic signs serve different purposes. For instance, brown is used for recreational and cultural interest signs, black is often employed for regulatory signs such as speed limits, and red is used primarily for stop and yield signs due to its association with alertness and caution. Each color has its significance, yet blue stands out as the color designated for informational purposes, helping to differentiate it from those that focus on regulatory or cautionary messages.
