Blue signs generally point you toward essential services like telephones, gas stations, food establishments, and lodging options. Imagine you’re on a road trip, and your stomach starts growling—what a relief it is to spot a blue sign that tells you there's a diner just off the next exit!

The role of blue signage is super crucial when you’re traveling. It enhances your experience by guiding you to places where you can fuel up, stretch your legs, and grab a bite to eat. The public has come to rely on these blue signals as much as they depend on GPS and navigation apps. And let’s face it, who doesn't appreciate a road map that helps steer you toward comfort during long drives?
