In the wake of the 1955 Le Mans disaster, the championship was still open after the British Grand Prix; although after that race (with the French Grand Prix already having been cancelled) the German, Swiss and Spanish Grands Prix were all cancelled.
Por mor da Traxedia de Le Mans de 1955, o campionato estaba aínda aberto despois do GP do Reino Unido, aínda que logo desa carreira (co Gran Premio de Francia que xa cancelado) cancelaronse tamén os Grandes Premios alemán, suízo e español.
