The National Highway Traffic Safety Administration (NHTSA) recently announced a proposed rule that would enable vehicle-to-vehicle (V2V) communication for all new light-duty vehicles. The proposed rule aims to prevent car accidents by letting vehicles communicate with each other.
This idea was first floated by the NHTSA nearly 3 years ago. If put into effect by 2019 as proposed, it would start phasing in the new rule in 2021, with 2023 set as the deadline for compliance.
How V2V Technology Works
V2V technology uses dedicated short-range communication (DSRC) to allow vehicles within about 1,000 feet of each other to exchange information about location, direction and speed. That info is sent 10 times per second, and vehicles with V2V can use that information to warn the driver about safety hazards.
If a vehicle has automated driving features, it can also use the V2V information to adapt its speed, direction, or braking in order to avoid crashes.
