Behind the wheel is Bernd Mayländer, who has led the field for over 700 laps since taking on the role in 2000 - a tally which would put him in the top 30 for most laps led in F1 history, if he were on the grid!
But, after all these years of driving the Safety Car, what's the biggest challenge in his role?
"I need to know where there has been an accident, where in the field I join the track, where the other cars are and if there are any cars that need to overtake me," Bernd explains.
"I also need to know where they can best overtake me without creating a risk to the other cars or the marshals. I'm in constant contact with race control. Every Safety Car is different - but that's what I like about it."
The Mercedes-AMG GT R is new for 2018. How did Bernd familiarise himself with his new set of wheels?
"Over the winter, I had five days in the new car on a high-speed test track in Nardo, Italy," he says. "It didn't take me too long to familiarise myself with it as I drove the GT S before.
"The new car is overall faster, though. It's about one second quicker per kilometre on the race track. The car is equipped with a specific communications and GPS mapping system and the highly visible safety lights. But most of the car - the engine, the gearbox, the suspension - is all standard."
