Waze Social GPS Navigation App for iOS Provides Voice Alerts for Hazards & Heavy Traffic

Have you ever been stuck in a horrendous traffic jam and not know why? In my experience tuning in to local radio stations rarely clears up the mystery. A quick check of Twitter might help. But, if you have traffic laws that prohibit fiddling with gadgets while driving, that is not an option. However, Waze, a free iPhone app which can crowdsource its users information can issue voice alerts for hazards and heavy traffic. It also has a voice recording feature to let you contribute traffic related information.
