Turkish Grand Prix pole sitter Lance Stroll is under investigation for an alleged breach of yellow flag rules during qualifying at Istanbul Park.
Stroll caused a shock when he claimed a maiden pole position in a rain-hit session, demoting the previously dominant Max Verstappen, to end Mercedes’ stranglehold on Saturdays.
But after the session a bulletin was issued by the FIA summoning Stroll for “allegedly non-respecting yellow flags” at Turn 7 in Q3.
It is understood that the yellow flag was caused when Racing Point team-mate Sergio Perez spun through the corner.
Stroll, following behind, passed the scene, with Perez facing the wrong way in the run-off and told to wait for his team-mate to go through before re-joining the track.
McLaren drivers Lando Norris and Carlos Sainz are also under investigation.
Norris also allegedly failed to adhere to yellow flags while Sainz has been called in to explain an apparent impeding of Perez during Q2.
