Which of these signs typically promotes safety and legality in public spaces?

Directional signs are specifically designed to provide guidance to the public and help ensure safety in various environments, such as roadways, parks, and public facilities. These signs convey important information about where to go, how to navigate, and what rules to follow, thus enhancing safety by reducing confusion and potential hazards.

For instance, directional signs can indicate exits, entrances, restrooms, and other vital services, ensuring that individuals can find their way safely. They also often include symbols or standardized icons that are universally understood, making it easier for people to follow directions regardless of language barriers.

In contrast, billboard signs primarily serve advertising purposes, promoting products or services rather than focusing on safety. Similarly, advertising signs are intended for marketing and may not contain any safety-related information. Political signs, while they can inform or influence public opinion, do not typically pertain to safety or legality in public spaces. Therefore, directional signs are the most relevant choice when considering signs that promote safety and legality.
