I know before I go, now!

I love checking this app out before I leave my house, or wherever I am! If there is traffic on my regular commute route, I go another way to save time and gas.

It also helped me find a park and ride where I could meet up with coworkers to carpool!

I even added IE511 on Twitter and Facebook. I want ALL the information this service has to offer.

Thanks for real time travel info

I have used this app daily since I downloaded it. The information and maps provided are accurate, clear and simple to use. And IE511 is the ONLY traffic info in Southern CA that has a great graphic for chain control in the mountain communities - finally!!!!

Very good app. Not having your selected Options stick in the app is a minor annoyance. When this is fixed, i will give this app five stars. The Show/Hide Incidents legend has to be selected each time the app is opened. Alerts--which identify freeway lane closures--are a huge plus! This is a must-have app for IE, Orange, and LA commuters. One of my favorite apps.
