Credit: Megan Ellis / Android AuthorityTL;DRA Google Maps bug is causing color-coded traffic lines (green, yellow, orange, and red) to vanish from the map interface, while underlying traffic data, road closures, and route calculations remain functional.The issue affects Android, iOS, and desktop web browsers.Standard fixes like toggling traffic layers, clearing cache, or switching accounts do not solve the problem.If you rely on Google Maps to gauge whether your commute is clear or jammed up with heavy traffic, you might want to double-check your screen before heading out. A growing number of Google Maps users on both Android and iOS are reporting a confusing UI bug that completely removes color-coded traffic lines from their navigation layer, leaving routes visually clear even when severe delays lie ahead.Reddit user Czerwony150 highlighted that traffic colors on Google Maps suddenly stopped working for them out of nowhere. This appears to be a display/rendering bug that prevents the green, yellow, orange, and red route lines from displaying in the map overview. You can still see some elements of the traffic layer, such as road closures and road maintenance work, but the visual traffic overview via colors is completely gone. Route calculations bring the traffic data back into view for that route, but the rest of the map overview remains devoid of traffic colors.
