2026 Hungarian GP: reported blue-flag glitch

Autosport reported a blue-flag system failure and a Carlos Sainz-Oscar Piastri clash in the 2026 Hungarian Grand Prix, with Sainz later penalised.

Autosport reported that a blue-flag system failure contributed to confusion in traffic during the 2026 Hungarian Grand Prix. The same outlet said Oscar Piastri, who arrived seventh in the drivers' championship on 92 points, had been leading before his second stop and rejoined behind Carlos Sainz.

Autosport also reported that the lapped Sainz then collided with Piastri on lap 38. Piastri, an Australian in his fourth Formula 1 season, was said to be frustrated by the contact but accepting of McLaren's strategy. Sainz, a four-time grand prix winner, was 15th in the standings on six points before the event.

Stewards later issued Sainz a five-second penalty, according to Autosport, which also reported that officials took the circumstances of the incident into account. With the race-control problem and the collision described in reports after the race, the full picture remains based on those accounts rather than an official combined explanation.
