FIA stewards reprimanded Kimi Antonelli after ruling the Mercedes driver had driven erratically during final practice at the Barcelona Grand Prix, the first reprimand of his 2026 season. Stewards reviewed video, telemetry and in-car footage before concluding he had breached the FIA International Sporting Code while frustrated by traffic, and Antonelli apologized for the incident. The formal warning carried no additional penalty, although five reprimands in a season bring an automatic 10-place grid penalty at the next race.
Antonelli was summoned before qualifying, and Lance Stroll was called to the same hearing after the two were involved in the traffic dispute in FP3. Antonelli complained on the radio after being blocked, then braked in front of the Aston Martin car. He finished the session seventh, behind Mercedes teammate George Russell.
In a separate ruling, stewards said Antonelli should have received a five-second penalty before his final pit stop in the Barcelona-Catalunya Grand Prix after exceeding track limits four times. One breach was identified only later in the race, which led to the count being completed late, and the stewards said Antonelli should have been warned sooner. He retired from the race and will not serve the penalty, which rules say would not carry over into a grid penalty next weekend. The stewards urged the FIA to review its procedures, and Stroll separately received a €600 fine on behalf of Aston Martin for speeding in the pit lane.
