In 2018, several single seater series such as Formula One, [[FIA Formula 2 Championship|Formula 2]] (with their new [[Dallara F2 2018]] chassis), and Formula E (with their new Spark SRT05e chassis) introduced a protection system to the cockpit called the [[Halo (safety device)|"halo"]], a wishbone-shaped frame aimed to deflect debris away from a driver's head. Despite initial criticism, including for the reason of obstructing the driver's vision, it gained some praise in the [[2018 Barcelona FIA Formula 2 round|Formula 2 sprint race in Catalunya]] when [[Nirei Fukuzumi]] spun and had the back of his car land on fellow countryman [[Tadasuke Makino]]'s halo.<!-- source? --> In the 2018 [[2018 Belgian Grand Prix|Formula 1 Belgian Grand Prix]], [[McLaren]] driver [[Fernando Alonso]] was sent airborne after being hit from behind by the [[Renault in Formula One|Renault]] of [[Nico Hülkenberg]] and struck the halo of [[Sauber]] driver [[Charles Leclerc (racing driver)|Charles Leclerc]], thereby saving the Monegasque driver from a visor strike.<ref>{{Cite web|url=https://www.autosport.com/f1/news/140545/halo-saved-leclerc-from-visor-strike-in-spa-crash|title=Halo saved Charles Leclerc from visor strike in Spa start crash|last=Noble|first=Jonathan|website=Autosport.com|date=6 December 2018 |language=en|access-date=2019-09-25}}</ref>

In [[2019 FIA Formula 3 Championship|2019]], the newly-formed [[FIA Formula 3 Championship]] introduced a halo to their new chassis which was unveiled at the [[2018 Abu Dhabi Grand Prix]].

In [[2020 IndyCar Series|2020]], the [[IndyCar Series]] adopted a halo combined with an aeroscreen, built by Red Bull Advanced Technologies. 

At the start of the 2020 [[2020_Bahrain_Grand_Prix|Bahrain Grand Prix]], [[Romain Grosjean]] collided with [[Daniil Kvyat]] in which his car broke in two and burst into flames as it split the barrier. The halo helped protect Grosjean from possible decapitation while it allowed him to escape from the fire.
