Works fine now

Please don't be intimidated by all the 1 star reviews. Given that when they were written, the app did not work. But it has been fixed for a while now and is actually quite useful. The traffic status is live and can be updated any time with the touch of a button. It also gives you access to live cameras so you can assess the traffic situation yourself. It is very simple, easy, and convenient to use. I think more people should know about it.

I use this app a lot ... good traffic predictor

I use this app all the time and I used it in both Northern and Southern California. It's very accurate and allows me to gauge traffic conditions and make decisions quickly.

I know California freeways like the back of my hand. For me it's easy to read, but other people may find it less so and want to use their GPS/Waze.

I find the Waze map interface to be horrid. Sigalert gives me a complete picture all at once.

Extremely to totally inaccurate

This is a terrible app. It would be more accurate to predict traffic blindfolded. Commonly I am in traffic at a standstill and Sigalert says I'm in a green area. Two days ago I was on the train to San Diego and looking at I-5 from the train I could see the traffic traveling at the train's speed (65-70 mph). I checked Sigalert and the app indicated the traffic was "red." This app is a total waste. Use other ones that we all know--- they are all better. This is the worst of them. Only good if you want a laugh. I don't understand why it's even available. - Live traffic reports
