What Does a Blue Stop Sign Mean? Blue stop signs might confuse new drivers
— they’re not common, especially in the U.S., where red stop signs are the standard.
Functionally the same: Blue stop signs still mean “stop,” but they’re not placed by
government officials. Private property only: You’ll often find them in Hawaii, where state
law prevents public signage on private land. So, property owners use blue signs to control
traffic on private roads, estates, or golf courses. Not legally standard: According to U.S. traffic law,
blue stop signs aren’t official under the Manual on Uniform Traffic Control Devices —
but drivers should still treat them seriously. Outside the U.S.: In other countries, blue signs
may mean restricted access or “go away,” rather than “stop.”
Bottom line: If you see a blue
stop sign — stop anyway. Whether it’s private or public, ignoring it could still land you a ticket depending on the situation
