The FIA has dropped the ruling the restricts the number of changes a Formula 1 driver could make to their helmet in a season.
The rule was implemented to help the public identify drivers more easily.
It was an unpopular ruling with drivers such as Sebastian Vettel, who was known for changing helmet designs on a regular basis.
The rule stated:
“In order for drivers to be easily distinguished from one another whilst they are on the track, the crash helmet of each driver must, with the exception of one event of the driver’s choice, be presented in substantially the same livery at every event during a championship season.
“A change to helmet livery will also be permitted if a driver changes team during a championship season.”
The decision to drop the rule was agreed on by both the Formula 1 teams and the World Motor Sport Council (WMSC), who noted that “unrestricted variations to driver helmet designs between races” will be allowed going forward.
