On-Board System Requirements for V2V Safety Communications
This standard specifies the system requirements for an on-board vehicle-to-vehicle (V2V) safety communications system for light vehicles1, including standards profiles, functional requirements, and performance requirements. The system is capable of transmitting and receiving the Society of Automotive Engineers (SAE) J2735-defined Basic Safety Message (BSM)  over a Dedicated Short Range Communications (DSRC) wireless communications link as defined in the Institute of Electrical and Electronics Engineers (IEEE) 1609 suite and IEEE 802.11 standards  – .
This standard is the first edition of on-board system requirements for V2V safety communications. It provides the information necessary to build interoperable systems that support select safety applications, which rely on the exchange of Basic Safety Messages.
