Hamilton was ordered to attend a hearing at 7 p.m. local time after being initially reported to the stewards for failing to respect waved double yellow flags 22 minutes after the start of the session.
Five minutes before the 7 p.m. hearing, a second summons was issued to Hamilton for obstructing Mazepin at Turn 8.
Hamilton’s yellow flag incident was distinct from a near collision with Haas driver Nikita Mazepin later in the session in which Hamilton was caught driving slowly down the race line on Turn 8 and forced Mazepin to take evasive action.
The interference is rarely dealt with as severely during a practice session as during qualifying, but the dangerous nature of the incident will likely be a factor in the investigation. At the time, FIA race director Michael Masi said none of the drivers had received warning flags about the other car’s presence.
If Hamilton is penalized for either incident it could have a big impact on the championship race, with the Mercedes driver currently eight points behind Verstappen with two races to go.
Hamilton can make sure the title battle goes through to the final race by finishing fifth or more in Saudi Arabia, but has to beat Verstappen this weekend for the best chance of securing his eighth title. world in Abu Dhabi.
