#2 Introduction of Halo
After some brief showings during free practice sessions, Halo -- a cockpit protection device, has finally become a part of F1's new driver safety additions to be made during the 2018 season.
Halo is a wishbone-shaped frame which is mounted above and around the drivers head and anchored to the monocoque forward of the cockpit.
It is a safety measure undertaken by the FIA after being a spectator to some major accidents such as that of Jules Bianchi, who unfortunately succumbed to his injuries after his accident during the 2014 Japanese Grand Prix.
FIA has developed and tested a lot of safety devices over the past few years and after feedback from the drivers and teams alike settled on Halo for the 2018 season.
