Red Bull's Max Verstappen escaped punishment for reversing onto the track in the opening Formula 1 practice session in Monaco.
Verstappen locked up and went straight on at Ste Devote and had to reverse onto the racing line to get back on track.
As he did so Sebastian Vettel's Ferrari was approaching the first corner and took to the pitlane exit road to avoid the Red Bull.
The stewards determined that Verstappen rejoined "under yellow flags and in a manner that posed no danger to the other drivers".
Verstappen was second-fastest behind team-mate Daniel Ricciardo in first practice.
