The sport's Strategy Group have decided not to bring it in at a meeting in Geneva
A safety device known as the "halo" will not be introduced onto Formula 1 cars next season.
It is designed to offer greater head protection around the cockpit but the sport's Strategy Group have decided not to bring it in at a meeting in Geneva.
The majority of drivers had previously voted for the change after a number of high profile accidents.
"It was decided that owing to the relatively short timeframe until the commencement of the 2017 Formula One season it would be prudent to use the remainder of this year and early next year to further evaluate the full potential of all options before final confirmation," the FIA explained.
"This will include undertaking multiple on-track tests of the ‘Halo’ system in practice sessions during the rest of this season and during the first part of the 2017 season."
