Click on traffic camera icons to see a camera image. Click on a CHP, lane closure, changeable message sign or chain control icon to view details for that marker. Traffic data is updated every few minutes. Load the latest data on the map using the Refresh button. If you choose to enable Geotargeted Notifications, this app will monitor your location in the background and alert you (via a Push Notification) to State Highway System road closures occurring near you. Continued use of background location may decrease battery life. Something not right with the data displayed on the map?
