Federal officials are planning to announce Monday whether automakers should be required to equip new cars and light trucks with technology that enables vehicles to communicate with each other to prevent collisions. Such vehicle-to-vehicle communication could transform traffic safety.

The Department of Transportation scheduled an announcement for midday. Transportation officials estimate the technology could prevent up to 80 percent of accidents that don’t involve drunken drivers or mechanical failure.

The group says the technology would add about $100 to $200 to the cost of a new car.
