Which sign color is commonly associated with rest areas and lodging?

The color blue is commonly associated with rest areas and lodging. In the context of road signage, blue signs provide information about services available to drivers, such as hotels, restaurants, and rest stops. This color is standardized across many states, making it easy for travelers to identify essential amenities and services during their journey.

Other colors like red typically indicate warnings or prohibitive signs, while brown signs usually direct travelers to recreational areas or points of interest, and orange is primarily used for construction zones and road work notifications. Therefore, recognizing blue signs as indicative of rest and lodging options is crucial for planning necessary stops while traveling.
