Information on routes, service areas, and points of interest are provided on a _________________.

The correct answer is guide sign. Guide signs are specifically designed to provide information about routes, service areas, and points of interest to drivers. They help navigate and inform road users about nearby amenities, directions to regions, and important landmarks, enhancing the overall travel experience.

Unlike road signs, which primarily convey rules and regulations or give warnings, guide signs focus on assisting drivers in finding their way and understanding local features. Directional signs do provide guidance but are often more specific in nature, directing drivers on which way to go rather than detailing various services or points of interest. Destination signs generally indicate the name of a location and distance but do not encompass the broader information provided by guide signs. Hence, guide signs are the most fitting choice for conveying comprehensive information on routes, services, and points of interest.
