What is the Safety Band?

The Safety Band is radio spectrum reserved specifically for transportation safety. In 1999, the Federal Communications Commission (FCC) allocated 75 MHz of radio spectrum in the 5.9 GHz band to be used for vehicle and infrastructure communications. Since then, infrastructure developers and vehicle innovators have developed countless smart technologies that rely on the Safety Band, and those innovations all have one thing in common: they depend on clear, uncluttered wireless signals that can help vehicles avoid accidents in the smallest fraction of a second.

Technologies developed to operate in the Safety Band carry messages that allow vehicles to “see” around blind curves and traffic in ways that conventional line-of-sight technologies (including LiDAR and radar) cannot. They enable traffic and emergency operations to flow safely and know what’s ahead, unaffected by fog, rain, snow and blinding sunbeams.

During 2017, there were over 6 million police-reported vehicle crashes in the U.S. that resulted in 37,133 lives lost, as well as 2,746,000 injuries. NHTSA estimates that safety applications enabled by vehicle-to-everything (V2X) could eliminate or mitigate the severity of up to 80 percent of non-impaired crashes, including crashes at intersections or while changing lanes.
