As per the FIA document,“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.”As per the rules, if there was a yellow flag at Marshal Post 1.2, Oscar Piastri had to respect it until the next Marshal Post, i.e., 1.3.
