Talking cars could soon take to the roads in a bid to reduce the number of accidents.
The government in the United States wants to cut the number of road deaths each year.

A radio signal constantly broadcasts the car's position, direction and speed to other vehicles.
The systems may even be able to brake automatically to avoid a crash.
