Sebastian Vettel, Carlos Sainz and Nikita Mazepin have received warnings after making illegal practice starts at Silverstone.

The race director’s notes for the British Grand Prix weekend stated drivers were required to make practice starts as far forward on the grid as possible.

On Saturday, Vettel, Sainz and Mazepin were adjudged not to have done so and investigations by the stewards were therefore launched into each of them.

After competing those investigations, the decision was taken to give all three drivers formal warnings but no penalties for the time being.

Regarding each of the drivers, it was stated that “future such infringements will likely result in a more severe penalty”.
