The 1955 season unfolded amid a series of fatal incidents, most notably the Le Mans disaster in which ex-Formula One driver Pierre Levegh and 83 spectators were killed, raising urgent safety concerns across motorsport governing bodies and national governments.
The ninth FIA Formula One season featured a six-race World Championship of Drivers spanning January to September 1955. Juan Manuel Fangio, driving for Mercedes, dominated the championship, securing his third title overall. The season was also marked by the deaths of multiple drivers including Alberto Ascari, Bill Vukovich, Manny Ayulo, and Mario Alborghetti.
In response to the Le Mans disaster and wider safety concerns, four Formula One Grands Prix were cancelled, leaving only seven championship rounds completed. This tied the 1955 season with the inaugural 1950 season for the fewest World Championship races held in a single Formula One year, a record that still stands as of 2025.
