What does a brown sign typically indicate?

A brown sign typically indicates parks and recreational areas. These signs are designed to provide information about recreational sites such as national parks, state parks, and various outdoor recreational facilities. The use of brown for these signs helps to distinguish them from other types of informational or regulatory signs, allowing drivers to quickly identify locations that pertain to leisure, nature, and tourism. This color coding is intentionally intended to guide drivers toward areas where they can engage in outdoor activities, enhancing their travel experience while also promoting safety on the road.
