The halo is a driver crash-protection system used in open-wheel racing series, which consists of a curved bar placed above the driver's head to protect it.
The first tests of the halo were carried out in 2016 and in July 2017. Since the 2018 season, the FIA has made the halo mandatory on every vehicle in Formula 1, Formula 2, Formula 3, Formula Regional, Formula E and also Formula 4 as a new safety measure.[1] Some other open-wheel racing series also utilize the halo, such as IndyCar Series, Indy NXT, Super Formula, Super Formula Lights, Euroformula Open and Australian S5000. The IndyCar halo is used as a structural frame for the aeroscreen.
