traffic light system
Road color signals
A traffic light system uses red, yellow, and green indicators to categorize items by risk, status, or priority—borrowing from the familiar signals that control vehicle flow.
Red typically means stop, danger, or urgent attention needed; yellow signals caution or moderate concern; green indicates safety or approval.
Common in health guidelines, project management, and food labeling: The report uses a traffic light system to show which targets we're meeting.
