A first vehicle-to-everything (V2X) device may operate in compliance with a first regional standard governing V2X Basic Safety Messages (BSMs) for a first geographical region, and a second V2X device may operate in compliance with a second regional standard governing V2X BSMs for a second geographical region. When the first V2X device is operating within the second geographical region, it may generate “global BSMs” in accordance with a multi-regional standard governing V2X BSMs. The second V2X device may process global BSMs generated by the first V2X device and may respond by generating its own global BSMs.
