Anchor Lede: Maybe your car already has sensors to detect some hazards…but soon it could be communicating with other cars and traffic signals to help you avoid accidents.

Randy Atkins: The system will get a real-life road test in about a year. With the National Academy of Engineering, Randy Atkins, WTOP News.


The first test will be in Ann Arbor, Michigan.
