Brown signs are used to indicate what?

Answer: D — Recreation and scenic area information

Brown signs are used primarily to provide information about recreation and scenic areas. These signs guide drivers to parks, historical sites, and other points of interest that enhance the travel experience. They help travelers locate opportunities for outdoor activities, such as hiking, camping, and sightseeing, making them essential for promoting tourism and leisure in various regions. In contrast, school zones are typically indicated by yellow signs, traffic regulations are marked by white or regulatory signs, and road construction areas are often indicated by orange signs. Each type of sign serves a distinct purpose, ensuring that drivers receive the proper information concerning different aspects of the road and travel environment.
