A blue sign typically indicates services such as telephones, gas stations, food establishments, and lodging. These signs are used to guide travelers to amenities and services they may require while on the road, making it easier for them to find essential resources during their journeys.

This type of signage plays a crucial role in enhancing the travel experience by clearly marking areas where drivers can conveniently access rest stops, restaurants, hotels, and fuel stations. The color blue has been standardized for this purpose to maintain consistency across various road systems, ensuring that drivers can quickly recognize and respond to these signs.

In contrast, other colors and sign shapes are designated for different types of information; for example, road conditions and hazards are usually indicated by warning signs that are often yellow, while speed limits and traffic laws are typically displayed on white regulatory signs. Historic locations and national monuments are generally marked with brown signs, which specifically identify points of interest.
