What is the primary purpose of accessibility signage in buildings?

The primary purpose of accessibility signage in buildings is to indicate where barrier-free facilities exist. Accessibility signage plays a crucial role in ensuring that individuals with disabilities can locate necessary features, such as ramps, elevators, and accessible restrooms, throughout a building. This type of signage is essential for promoting inclusivity and allowing everyone, regardless of their physical abilities, to navigate the space effectively.

The other choices focus on different functions of signage but do not capture the distinct role of accessibility signage. While providing directions to different building areas is an important aspect of general signage, it does not specifically address the needs of individuals requiring barrier-free options. Marking emergency exits is another critical function of signage, but this is about safety rather than accessibility. Informing about building regulations serves a different purpose related to compliance and codes, which is not the primary focus of accessibility signage.
