A brown highway sign generally signifies what?

A brown highway sign is specifically designed to provide information about recreational, historic, and scenic sites. This color coding is part of the standardized system of highway signs used across the United States, which helps drivers quickly identify the type of information being conveyed. Brown signs can indicate national parks, historical landmarks, and other points of interest that often enhance travel experiences by directing motorists to enjoyable attractions and activities.

The other options represent different functions for highway signs. Signs indicating dining and shopping locations typically use a different color, while fuel and lodging services are usually represented with blue signs.
