Answer:
Blue road signs tell you what roads, cities, and services are nearby.
Step-by-step explanation:
The blue road sign usually consist of information about locality, gas station, rest area, and hotels.
Data signs are normally found on expressways and thruways. They are ordinarily set before an exit to demonstrate what administrations are accessible. These signs can tell drivers if there is lodging, corner stores, nourishment, medical clinics, air terminals, and different administrations. Some nearby data signs will likewise give explicit names of administration stations, cafés, and so on.
Toward the finish of an exit ramp, you will ordinarily observe blue signs with bolts pointing toward where you can discover those administrations.
