The greatest sport on four wheels unveiled some new rules for the 2023 season this week. Starting in the new season, drivers will be required to wear underwear and socks, among other things.
It should be noted, a fire-resistant head sock/helmet skirt, underwear and socks. Specific SFI or FIA-rated gear will be required, falling in-line with other series. It remains unknown at this time how this will be checked.
Our sister station, WLS-AM, is a proud partner of the Motor Racing Network and the home of the Chicago Street Race this summer. More info can be found here.
