Max Verstappen claims pole position for Saturday’s F1 Singapore Grand Prix Sprint, but the result is under review after stewards examine a possible yellow-flag infringement. Multiple outlets report that Verstappen is being investigated for overtaking Lewis Hamilton while yellow flags were active during Sprint Qualifying.

The incident is linked to a separate stoppage caused by Sergio Perez’s crash. Perez damages his car after hitting the Turn 5 barrier, prompting a yellow-flag zone. As Verstappen is alleged to have passed Hamilton during that period, the stewards summon him to determine whether he breached F1 rules on racing under caution.

Across the reports, the common points are Verstappen’s Sprint pole achievement and the fact that an investigation is underway regarding the yellow-flag incident involving Hamilton. The outlets differ mainly in wording and emphasis, but all describe the same sequence: Perez’s accident triggers yellow flags, and Verstappen’s actions during that window are now being assessed.
