Four-times world champion Sebastian Vettel will appear before Bahrain Grand Prix stewards on Sunday for allegedly failing to respect warning flags in qualifying for his first race with Aston Martin.
The summons for not respecting double-yellow flags at turn one capped a frustrating day for the German, who had hoped for a strong showing after leaving Ferrari, but instead qualified 18th of the 20 drivers.
He had been earlier cleared, along with others, of ignoring single yellow flags waved at turn eight.
Vettel had to slow when Russian rookie Nikita Mazepin spun his Haas, which meant the Aston Martin driver was unable to set a faster lap and reach the second phase of qualifying as expected.
