The Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) will move ahead of its timetable for its proposal to require vehicle-to-vehicle communication devices in new cars. That means it will send in a proposal by the end of 2015 rather than in 2016. It also will work to accelerate testing necessary to ensure that vehicle-to-vehicle and vehicle-to-infrastructure transmissions are free from radio interference within 12 months after the industry makes production-ready devices available for testing.
