Yellow flag.
Daniel Ricciardo reported an issue over his team radio on lap 47 after coming to a stop on the side of the track. McLaren later confirmed it was an oil leak, but the safety car was deployed, giving George Russell, Charles Leclerc and Max Verstappen—who made up three through first, respectively—a free pit stop for soft tires. It looked like it could have been a mad dash, but track marshals struggled to get Ricciardo’s McLaren off of the track, which had to be lifted by the crane.
Instead of red-flagging the race, the Italian Grand Prix was finished behind the safety car even though, as Leclerc said over the radio, the track was clear. Boos echoed throughout Monza from the Tifosi fans.
