What color is an evacuation route sign?

The correct color for an evacuation route sign is blue. This color is used to indicate routes that guide motorists to safety during emergencies, such as natural disasters or other situations requiring evacuation. Blue signs are typically associated with travel and information-related guidance, making them an appropriate choice for directing people toward evacuation paths. The use of blue helps to differentiate these signs from others that indicate different types of information or regulations.

In contrast, other colors have specific meanings; for example, green is often used for guide signs, red is associated with prohibitive or stop signs, and yellow indicates caution or warning signs. The distinct use of blue for evacuation routes ensures that they are easily recognizable and understood during critical situations.
