Speaking about the matter, Masi explained that once Kvyat had lodged a formal request to change colours, then he had no choice but to reject it because it was his third different design of the year.
While many observers have pointed out other drivers running a number of different designs this year, Masi has suggested that has only happened because not everyone has asked in advance.
max verstappen is one driver who has used a number of different coloured helmets this year, but Masi said that he had not been informed beforehand about any change of helmet design.
Masi has suggested that the situation surrounding helmet designs is something that may need looking at again.
No driver has yet been called up over using a different design beyond his one joker, and Masi said it would not be up to him what sanction would be imposed for a rule breach.
