What type of information is provided by blue signs?

Blue signs are specifically used to indicate motorist services. This includes information about services such as gas stations, rest areas, lodging, food, and hospitals, which are essential for travelers on the road. These signs help drivers locate necessary amenities during their journey, especially in areas where they may be unfamiliar.

Other types of signs serve distinct purposes; for example, signs that provide distance to a destination typically use green. Regulatory information, which outlines rules such as speed limits or no parking zones, is shown on white signs with black text. Recreational sites are usually indicated by brown signs, helping to direct travelers to parks and outdoor attractions. Understanding the specific colors and types of signs is crucial for safe driving and navigation.
