What does a blue traffic sign typically signify?

A blue traffic sign typically signifies services such as gas, food, and lodging. This color is designated by the Manual on Uniform Traffic Control Devices (MUTCD) to indicate areas where drivers can find services that support their travel needs. When drivers see a blue sign, they can expect to find amenities that cater specifically to their comfort or convenience while on the road.

For example, blue signs will often be found near rest areas or exits that lead to restaurants, hotels, and gas stations, making it easier for drivers to plan their stops. Understanding this symbolism is crucial for navigating roadways effectively and encountering the necessary services during a trip.
