No Traffic Flow? Zoom in Closer

How to use the Napa Traffic Map

Traffic flow lines: Red lines = Heavy traffic flow, Yellow/Orange lines = Medium flow and Green = normal traffic or no traffic*. Black lines or No traffic flow lines could indicate a closed road, but in most cases it means that either there is not enough vehicle flow to register or traffic isn't monitored. Also, If you do not see traffic flow, you can zoom in closer to reveal localized data. If you are unable to pan the map, press here (to focus off of the map) and try again.

* In known extreme weather events or accidents, the map provider may still show green lines, even if lanes or the entire road is closed.
