What does a blue road sign typically indicate?

A blue road sign typically indicates information about services such as gas, food, and lodging. These signs are designed to assist drivers by providing essential information on amenities that are available along the route. This can include locations for rest areas, gas stations, hotels, and restaurants, helping travelers to easily find necessary services during their journey.

In contrast, other types of road signs serve different purposes: signs that give directions to the nearest city or major landmarks are usually green, while warnings about road conditions, such as hazards or changes in the road environment, are commonly represented in yellow. Regulatory signs, which inform drivers about the laws and rules they must follow, such as speed limits or no parking zones, are typically displayed in red or white. Understanding the color code and meaning of these signs is crucial for safe and informed driving.
