Williams team principal James Vowles declared the blue flag incident at the Hungarian Grand Prix stemmed from a malfunctioning FIA GPS system, absolving Carlos Sainz of deliberate blame.
Collision Chaos
During the opening lap, Sainz and Oscar Piastri collided after a series of confusing flag instructions. Vowles told the Vowles Verdict that the team’s own failure to signal the correct driver to yield contributed to the crash. Sainz ultimately received a five‑second penalty and finished 18th, while Piastri’s race ended with a gearbox failure.
GPS System Flaw
The FIA’s automated blue‑flag system, set to trigger a warning when a leader is 1.6 seconds behind and enforce the rule at 1.2 seconds, collapsed under race conditions. Marshals initially resorted to hand‑waving traditional blue flags before switching to flashing blue‑light panels that failed to indicate which car needed to yield.
Vowles explained how the flashing lights proved ambiguous: Fernando Alonso, who was behind Sainz, could not easily discern the correct lane to relinquish. In a moment when Alonso remained ahead of Oscar on the inside, Sainz was forced to move back, creating a chain of indecision that culminated in the collision.
Aftermath
Williams admitted fault in the sequence of flagging errors and highlighted the need for a more reliable mechanism when FIA systems fail. With the blue‑flag breakdown officially acknowledged, the grid remains unchanged: Sainz’s penalty, Piastri’s retirement, and Williams still positioned for a race‑goal finish.
