Sebastian Vettel was supposedly banned from drinking champagne on the podium as he celebrated winning Sunday's Turkish Grand Prix.
British newspapers report that the championship leader was told he must resist drinking the champagne due to Turkey's new alcohol age limit of 24.
"It had been said in the drivers' briefing. The law is 24 and he is 23," confirmed Red Bull team boss Christian Horner.
The alcohol advertising ban in Turkey also meant teams had to remove some logos from their cars, such as Sauber's usual Tequila sponsor.
