Guide and Informational Signs
Guide and Informational Signs
Guide signs help you navigate, find services, and confirm your route; they do not usually command a driving action. The exam tests color coding, route marker shapes, exit sign reading, and service symbols. North Carolina follows the national color system: green for destinations, distances, exits, and mile markers; blue for motorist services; brown for recreation and cultural sites; and white-and-black for some regulatory or informational messages.
Core rules
- Green signs give directions and distances. Exit signs typically show the exit number, destination, and distance; an EXIT ONLY sign means that lane must exit.
- Blue signs show services such as gas, food, lodging, hospital, and rest areas. They tell you what is available, not that you must stop.
- Brown signs point to parks, historic sites, and recreation areas.
- Route markers identify the road: the interstate shield, the U.S. route shield, and the North Carolina state route marker. Learn their shapes so you can confirm a route at a glance.
- Mile markers are green with white numbers and are useful for giving your location in an emergency.
- Read guide signs early. Make lane changes and exit decisions well before the ramp, using mirrors and signals.
Worked example
You see a green sign reading EXIT 25 - MAIN ST 1 MILE and you want that exit. The sign is advance guidance: you have about one mile to move into the correct lane. Check traffic, signal, and merge into the exit lane; do not brake suddenly at the gore area or reverse if you miss it. If you miss the exit, continue to the next legal exit and turn around.
Traps that cost marks
Do not confuse blue service signs with green destination signs. Do not treat a brown recreation sign as a warning. Do not wait until the exit ramp to change lanes. Do not cross the solid white gore area to catch an exit. And do not use a route marker as proof of direction-confirm with the destination and arrow.
