Which type of map would help someone planning a road trip?

Choosing city or state road maps is ideal for planning a road trip because these maps specifically focus on showing road networks, highways, and routes suitable for travel. They often include details such as road names, mile markers, and points of interest along the way, making them user-friendly for navigation. For someone who is driving, having a clear understanding of the routes, traffic conditions, and nearby amenities is crucial, which is why road maps serve this purpose effectively.

In contrast, tourist maps focus more on attractions and destinations within a specific area rather than the roadways themselves. Topographic maps illustrate the terrain and are valuable for hiking or outdoor activities, but they do not provide the detailed road information needed for driving. Geographic maps present a broader view of land features and political boundaries, but they lack the necessary detail for effective road navigation. Thus, city or state road maps are specifically tailored for road trips, making them the best choice.
