Max Verstappen has been summoned to the stewards at the Dutch Grand Prix over allegedly passing Lance Stroll under red flag conditions during practice.
The second practice session at Zandvoort was halted when Lewis Hamilton suffered a loss of power and stopped his Mercedes W12 at Turn 8.
Stewards have alleged that Verstappen overtook Aston Martin driver Stroll between Turns 10 and 11 while the red flags were shown.
Verstappen was on a hot lap while Stroll was circulating off-line on a slow lap when the pass took place.
Verstappen must report to the stewards, along with a Red Bull representative, at 10:45 local time.
If found to have transgressed Verstappen faces a potential grid penalty for his home grand prix.
