Guide and Informational Signs: Routes, Services, and Destinations
Guide signs direct and inform
Guide signs help you navigate and find services. They do not usually impose legal duties. Green signs give destinations, distances, exits, route names, and directions. Blue signs show motorist services such as gas, food, lodging, hospitals, and rest areas. Brown signs point to recreation, parks, historic sites, and cultural attractions. White-on-green or white-on-blue is common; route markers use their own designs.
Route markers are guide signs too. The interstate shield identifies the Interstate system. The U.S. route shield identifies federal highways. Arkansas state routes use a distinct state marker. An exit number tells you the mile location of an interchange, not the speed or lane requirement. Mile markers help you report your location in an emergency.
Traps: a blue service sign is not a regulatory command. A brown recreation sign does not mean the road is unpaved or closed. An alternate route marker does not mean the main route is necessarily blocked; it identifies an official alternate path. A guide sign showing a destination does not guarantee that the road is open all the way.
Worked example: You see a blue sign with a gas pump and a food symbol at Exit 42. It means those services are available at that exit. It does not set a speed, require you to exit, or promise that every service is open 24 hours.
Rule of thumb: green = go and navigate, blue = services, brown = recreation. Read guide signs for planning, not for legal commands.
