Which type of signs provide information about directions or services?

Informational signs are designed specifically to provide guidance and details about directions or available services to drivers. These signs typically include symbols or text to indicate the location of services such as gas stations, rest areas, hospitals, and other points of interest, as well as directional information to help navigate roads and highways.

Regulatory signs, on the other hand, establish laws and regulations that drivers must obey, such as speed limits or no parking zones. Warning signs serve to alert drivers to potential hazards or changes in road conditions, like sharp curves or pedestrian crossings. While these types of signs are crucial for safe driving, they do not provide the directional or service-oriented information that informational signs do. Hence, informational signs uniquely fulfill the purpose of guiding drivers regarding directions and services.
