Google Maps allows you to show or hide a traffic conditions layer overlaid on the map.
To turn this feature on or off:
- Open the map view.
- Touch the Layers menu icon.
- Select the Traffic option. This option may also be directly in the main menu.
Google Maps will either show current color-coded traffic conditions on highways and roads where data is available or display a message that data is unavailable.
- Green: more than 50 miles per hour or 80 kilometers per hour
- Yellow: 25 - 50 miles per hour or 40 - 80 kilometers per hour
- Red: less than 25 miles per hour or 40 kilometers per hour
- Red/Black: very slow, stop-and-go traffic
- Gray: no data currently available
These speeds don't apply to traffic on smaller roads, such as those within cities, which have lower speed limits. For roads smaller than highways, the colors give an indication of the severity of the traffic. Green means that traffic conditions are good, yellow means fair, and red or red/black means poor traffic conditions.
