Cars talk to each other in gov't safety initiative

Thousands of vehicles are now talking to each other on the road to improve safety.

The U.S. Department of Transportation launched a year-long test of nearly 3,000 cars, trucks and buses in Ann Arbor, Michigan, on Tuesday. The vehicles are equipped with Wi-Fi technology so they can talk to each other in real time, sending signals that warn of safety hazards.

Drivers are warned when a car is about to miss a stop sign or when another car has entered another driver's blind spot.

Safety officials believe if the cars can communicate with each other they can help avoid crashes and improve traffic flow.
