The FIA will investigate the incident during Sunday’s Singapore Grand Prix that saw a marshal remain on-track when the race resumed at Marina Bay.
An early safety car period was called in Singapore following a crash for Nico Hulkenberg at the start, his Force India requiring removal by the marshals from the main straight.
Race control confirmed that green flag running would resume on lap three, with Nico Rosberg leading the field away.
However, TV footage showed a marshal running across the main straight just before the cars arrived at Turn 1, narrowly avoiding being caught out after getting out of the firing line.
According to a report from Autosport, the marshal was given the call to head out on-track after the circuit had been declared clear three times.
The FIA will now investigate the incident, saying it takes the matter “seriously” and that “everything will be done to ensure this does not happen again”.
Rosberg was asked about the incident after his winning for the eighth time this year in Singapore, admitting that the green flag call came as a surprise.
“That was pretty hairy, for sure,” Rosberg said.
“I think just as we didn’t expect the restart, he didn’t either, I think, because the restart was somehow pretty abrupt.
“But he got out of the way just about in time so it was OK. Of course we all had to drive a bit carefully through there.”
