Yes, a hospital sign is considered a regulatory sign, but it also has elements of a guide sign depending on its specific purpose. Regulatory signs are designed to communicate rules and regulations to ensure public safety and compliance, such as speed limits or traffic restrictions. Hospital signs typically fall under the broader category of traffic signs that provide important information for drivers. They often indicate the location of a nearby hospital or direct traffic to ensure emergency access routes are clear. While their primary role may not always be regulatory, they contribute to maintaining safety and order, which aligns with the function of regulatory signage.
