Four drivers have been summoned to the São Paulo Grand Prix race stewards following alleged rules breaches during qualifying at Interlagos.
FIA Race Director Niels Wittich addressed recent issues regarding impeding at the end of the pit lane following incidents in Singapore and, following clarification, Mexico last weekend.
Whilst drivers were cleared on those occasions, Wittich has introduced a mandate for drivers to wait until the pit exit lane - and not the fast lane - to create gaps for their qualifying efforts.
In Brazil, this means drivers must get past the Turn 3 apex point of the pit lane before pulling to the left, allowing space for rivals to pass should they need to.
But George Russell and Esteban Ocon Pierre Gasly all allegedly broken that directive, thus earning themselves a trip to the stewards along with Sergio Perez who was caught up in the incidents.
