The rules could take effect in just a couple years and would add as much as $350 to a vehicle's price.
The United States Department of Transportation believes that vehicle-to-vehicle (V2V) communication would make driving significantly safer, including preventing around 1,000 deaths a year. The agency is proposing a mandate that would bring a standardized version of the tech to every new vehicle sold in the country.
As the name implies, V2V communication lets vehicles exchange information with each other. Under the DOT’s proposed standard vehicles would send and receive this data to traffic up to 984 feet (300 meters) away, even those not visible to a driver. Each vehicle does not have a specific I.D, and the transmissions don’t include any personal info, which should reduce privacy concerns. The system would then act as an extra backup to existing safety devices. For example, your car’s adaptive cruise control would know about stopped traffic ahead and could react sooner to the situation.

V2V communication also has the potential of making autonomous vehicles even better. They already have a bounty of sensors, but V2V can sense traffic that’s even farther away. By combining the two, there’s more data that software can use for making decisions about controlling the vehicle.
NHTSA estimates the V2V equipment and infrastructure would add $341-$350 to a vehicle’s cost in 2020 and would fall to $209-$235 by 2058. The agency’s calculations indicate the tech would save $54.7 to $74.0 billion after fleet-wide adoption because of the improved safety.
The DOT is now opening up the proposal for public comment for 90 days. Once implemented automakers would need to put the tech on half of their new vehicles within two years, according to Automotive News. The mandate would extend to a company’s entire lineup in four years.
The government is also looking at standardizing Vehicle-to-Infrastructure (V2I) communications. This is similar technology that allows exchanging information with things like traffic lights, stop signs, and even work zones. Audi is already experimenting with a similar system by telling drivers how long until a traffic light changes.

U.S. DOT ADVANCES DEPLOYMENT OF CONNECTED VEHICLE TECHNOLOGY TO PREVENT HUNDREDS OF THOUSANDS OF CRASHES
Proposed Rule Would Mandate Vehicle-to-Vehicle (V2V) Communication on Light Vehicles, Allowing Cars to “Talk” to Each Other to Avoid Crashes
WASHINGTON—Citing an enormous potential to reduce crashes on U.S. roadways, the U.S. Department of Transportation issued a proposed rule today that would advance the deployment of connected vehicle technologies throughout the U.S. light vehicle fleet. The Notice of Proposed Rulemaking would enable vehicle-to-vehicle (V2V) communication technology on all new light-duty vehicles, enabling a multitude of new crash-avoidance applications that, once fully deployed, could prevent hundreds of thousands of crashes every year by helping vehicles “talk” to each other.
“We are carrying the ball as far as we can to realize the potential of transportation technology to save lives,” said U.S. Transportation Secretary Anthony Foxx. “This long promised V2V rule is the next step in that progression. Once deployed, V2V will provide 360-degree situational awareness on the road and will help us enhance vehicle safety.”
In February 2014, Secretary Foxx announced the Department would accelerate its work to enable V2V, directing the Department’s National Highway Traffic Safety Administration (NHTSA) to begin work on the rulemaking. NHTSA issued an Advance Notice of Proposed Rulemaking in August 2014. The advancement of the V2V rulemaking complements the Department’s work to accelerate the development and deployment of automated vehicles.
“Advanced vehicle technologies may well prove to be the silver bullet in saving lives on our roadways,” said NHTSA Administrator Mark Rosekind. “V2V and automated vehicle technologies each hold great potential to make our roads safer, and when combined, their potential is untold.”
The proposed rule announced today would require automakers to include V2V technologies in all new light-duty vehicles. The rule proposes requiring V2V devices to “speak the same language” through standardized messaging developed with industry.
Separately, the Department’s Federal Highway Administration plans to soon issue guidance for Vehicle-to-Infrastructure (V2I) communications, which will help transportation planners integrate the technologies to allow vehicles to “talk” to roadway infrastructure such as traffic lights, stop signs and work zones to improve mobility, reduce congestion and improve safety.
NHTSA estimates that safety applications enabled by V2V and V2I could eliminate or mitigate the severity of up to 80 percent of non-impaired crashes, including crashes at intersections or while changing lanes.
V2V devices would use the dedicated short range communications (DSRC) to transmit data, such as location, direction and speed, to nearby vehicles. That data would be updated and broadcast up to 10 times per second to nearby vehicles, and using that information, V2V-equipped vehicles can identify risks and provide warnings to drivers to avoid imminent crashes. Vehicles that contain automated driving functions—such as automatic emergency braking and adaptive cruise control—could also benefit from the use of V2V data to better avoid or reduce the consequences of crashes.
V2V communications can provide the vehicle and driver with enhanced abilities to address additional crash situations, including those, for example, in which a driver needs to decide if it is safe to pass on a two-lane road (potential head-on collision), make a left turn across the path of oncoming traffic, or determine if a vehicle approaching an intersection appears to be on a collision course. In those situations, V2V communications can detect developing threat situations hundreds of yards away, and often in situations in which the driver and on-board sensors alone cannot detect the threat.
Privacy is also protected in V2V safety transmissions. V2V technology does not involve the exchange of information linked to or, as a practical matter, linkable to an individual, and the rule would require extensive privacy and security controls in any V2V devices.
The notice of proposed rulemaking will be open for public comment for 90 days.
