The Obama administration said Monday it is taking a first step toward requiring that future cars and light trucks be equipped with technology that enables them to warn each other of potential danger in time to avoid collisions.

The agency said it will begin drafting rules to require the technology in new vehicles. (AP Photo/Susan Walsh, File)
