Points of interest can be found by reading ________ signs.

Points of interest are indicated by brown signs, which are specifically designed to provide information about recreational areas, historical sites, and cultural landmarks. These signs help drivers locate parks, museums, and other attractions that may not be directly related to travel needs, but are of interest to those looking to explore the area. The use of brown signage is standardized to ensure that travelers can easily recognize and locate these types of points of interest while navigating.

In contrast, green signs typically indicate directional information related to roadways and distances, blue signs denote services such as fuel, food, and lodging, while white signs mainly convey regulatory information, such as speed limits or legal restrictions, rather than points of interest.
