What color are informational or guide signs commonly?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer: (C)

Informational or guide signs use color coding to quickly communicate the type of information a driver needs. Green is chosen for directional and destination information because it signals guidance and lets drivers recognize non-regulatory messages at a glance. In the standard system, green signs with white letters indicate routes, exits, directions, and distances, providing navigation help. This color is distinct from red signs (regulatory or stop), yellow signs (warning), and blue signs (motorist services). So green is the color most commonly associated with informational or guide signs.
