Oscar Piastri learns stewards' verdict after Azerbaijan GP investigation

Oscar Piastri has been handed his first reprimand of the season by the F1 stewards at the Azerbaijan Grand Prix.

The McLaren driver was called before the stewards for a yellow-flag infringement during FP2 at the Baku Street Circuit.

Although there appeared to be mitigating circumstances, the stewards found the championship leader had contravened the rules.

A stewards' statement read: "A yellow flag was displayed at Marshal Post 1.2, and green light was shown at light panel 3.

"Drivers had been instructed that if they see a green light, they must take the action required under a yellow flag condition, even if they had not been shown the yellow flag. 

"In this case, the driver had passed Marshal Post 1.2 when the yellow flag was shown for the first time, but was able to see the green light at light panel 3.

"The yellow flag was withdrawn less than one second after the green light became visible to the driver.

"Therefore, technically a breach of the regulations has occurred; however, because of the mitigating circumstances above, the penalty imposed is reduced to a Reprimand.

"This is consistent with previous similar incidents."
