Signalfärg

Signalfärg, also known as traffic signal color or traffic light color, refers to the colors used in traffic control systems to regulate the flow of vehicles and pedestrians at intersections. The most common signalfärger are red, yellow, and green, which are universally recognized and standardized. Red indicates that drivers and pedestrians must stop and wait for the signal to change. Yellow, or amber, signals drivers to prepare to stop, as the light will soon turn red. Green indicates that drivers and pedestrians may proceed with caution, as the light will soon turn yellow and then red. In some countries, additional signalfärger may be used, such as blue for trams or buses, or flashing yellow for school zones. The design and timing of signalfärger are crucial for ensuring safe and efficient traffic flow, and are typically managed by traffic engineers and authorities.
