What type of signs are usually brown with white lettering?

Answer: B — State parks and recreation

The correct answer indicates that signs that are usually brown with white lettering specifically relate to state parks and recreational areas. Brown signs are employed to guide drivers to locations of interest such as parks, historical sites, and outdoor recreation opportunities. This color coding helps to differentiate these types of destinations from other information that signs convey. These signs serve an important purpose in providing information about recreational facilities and natural areas, making them easily recognizable for those seeking to explore or enjoy nature. While other types of signs use different color schemes to convey warnings or regulatory information, brown signs are distinctively tailored to direct attention toward recreational and cultural sites.
