What color are the letters on direction signs?

Direction signs are designed to provide clear and easily recognizable information to drivers. In North Dakota and across the United States, direction signs use white letters on a green background. This color combination helps ensure high visibility and contrasts effectively against the green, which is often associated with guidance and direction.

The use of white letters on a green background is standardized to convey directional information such as the names of streets and highways, points of interest, and other navigational aids. This consistency in signage helps promote safety by allowing drivers to quickly identify essential information while on the road.

Other color combinations, such as yellow on black, are typically used for warning signs, while signs with blue backgrounds often indicate services or amenities. Thus, the clear identification of white on green for direction signs is crucial for effective navigation.
