MEXICO CITY -- Max Verstappen's pole position at the Mexican Grand Prix is in doubt after he was summonded to the stewards to explain whether he slowed for yellow flags at the end of his fastest lap.
Verstappen was on provisional pole from his initial Q3 attempt and then improved at the end of the session, despite the fact he had to pass Bottas' wrecked Mercedes at the final corner to do so. Bottas had crashed out moments earlier while attempting to improve on sixth position which prompted marshals to wave yellow flags through that part of the circuit.
