Formula One cars will be fitted with the Halo frontal protection system from the 2018 season, the FIA has announced.
The decision was confirmed following Wednesday's meeting of F1's strategy group - with representatives of all 10 teams in attendance.
An alternative concept known as the Shield was trialled at Silverstone last week, but Ferrari's Sebastian Vettel complained it made him dizzy.
And despite reports the majority of teams rejected the introduction of the Halo at Wednesday's meeting, it will be introduced from next season.
"Following the unanimous agreement of the Strategy Group, in July 2016, to introduce additional frontal protection for Formula One and the repeated support from the drivers, the FIA confirms the introduction of the Halo for 2018," an FIA statement read.
"With the support of the teams, certain features of its design will be further enhanced.
"Having developed and evaluated a large number of devices over the past five years, it had become clear that the Halo presents the best overall safety performance."
