The US Department of Transportation ( DOT ) is proposing a rule requiring new vehicles to have vehicle - to - vehicle ( V2V ) communication technology . V2V will allow cars to communicate with each other to warn drivers about potential accidents . The technology uses short - range radios for communication and can send data on location , speed , direction and braking . It will have a range of around 500 m , greater than radar or camera coverage . The DOT anticipates the system would be used to warn drivers of oncoming vehicles , especially while turning at junctions or changing lanes . Earlier this year , the DOT also publishes guidelines for self - driving vehicles .
The US Department of Transportation (DOT) is proposing a rule requiring new cars to have vehicle-to-vehicle (V2V) communication technology. V2V systems allow cars to communicate with each other to warn drivers about potential accidents. The technology uses short-range radios for communication and can send data on location, speed, direction and braking. It will have a range of around 300m, greater than radar or camera sensors. The DOT anticipates the system would be used to warn drivers of oncoming vehicles, especially while turning at junctions or changing lanes. Earlier this year, the DOT also published guidelines for self-driving cars.
