The United States Department of Transportation has announced that it’s taking steps to implement vehicle-to-vehicle (V2V) communications in an effort to prevent crashes, deaths and injuries caused by motor vehicle use.

V2V allows cars to “talk” to one another—exchanging basic safety-relevant data, such as speed, direction, and relative position—10 times per second. When cars share this information at such a fast rate, they can “see” all of the vehicles around them, sense the possibility of a crash, and warn drivers to avoid the crash.




V2V has the potential to help drivers avoid or mitigate 70 to 80 percent of vehicle crashes involving unimpaired drivers, and that could help prevent many thousands of deaths and injuries on our roads every year.

This announcement comes after a year of testing conducted by the agency involving 3,000 cars in Ann Arbor, Mich. The pilot program was designed to determine the viability of widespread vehicle-to-vehicle communications as a means to improve safety on the road.
