Guide and Informational Signs
Guide and Informational Signs
Guide signs show routes, destinations, distances, exits, and services; they help you navigate rather than command or warn. The Guam exam checks color and shape recognition, exit-sign reading, and the difference between a guide sign and a regulatory sign.
Core rules
- Green signs carry destinations, distances, route guidance, exits, and street names. On freeways and major routes, exit signs often include an exit number and a directional arrow.
- Blue signs mark motorist services: gas, food, lodging, and hospitals. They do not warn of hazards and do not set speed limits.
- Brown signs mark recreation and cultural interest areas, such as parks, historic sites, and museums. Brown is not the service color.
- White rectangles with black legends can be regulatory or informational. Read the words: a white sign that says “SPEED LIMIT” is regulatory; a white route marker identifies a route.
- An “EXIT ONLY” sign with a downward arrow means that lane must leave the roadway. A green destination sign with an arrow shows where the destination lies, not that every driver must turn.
- Route markers identify numbered routes; they do not authorize a speed or a turn. Overhead lane signs apply to the lanes beneath them.
Worked example
You are driving on a major Guam route and see a green sign reading “Hagåtña 2” with a left-pointing arrow, followed by a blue sign showing a gas pump and “2 MILES.” The green sign tells you the destination and distance and that the route to Hagåtña bears left at the upcoming junction; it is guidance, not a command to turn from your current lane. The blue sign tells you a fuel station is two miles ahead; it is a service sign, not a warning or a speed limit. If you need fuel, plan the lane change early, but do not stop in a travel lane to read the sign.
Traps
Do not look for services on a brown recreation sign or for park information on a blue service sign. Do not treat a green destination arrow as a regulatory turn arrow. Do not stay in an “EXIT ONLY” lane hoping it continues. Do not confuse a route marker with a speed-limit sign. Guide signs can be overhead and lane-specific, so read the arrow that sits above your lane.
