Fourth red flag on Friday in Barcelona as Ricciardo stops car

After having just one red flag in the first two days of testing in Barcelona, there have been four now on Friday as Daniel Ricciardo was the latest to cause the session to be stopped - his Renault was parked on-track with engine problems.

In almost the final our of the first testing week at the Circuit de Catalunya, the Aussie had to pull over in his RS20 and take the long way back to the pitlane. He did not look happy at all, although at time of writing, the 30-year-old is back on track in his Renault to put in more laps.

This was the fourth red flag of the day after an early one for Sebastian Vettel, followed by red flags for Nicholas Latifi, Kevin Magnussen and now Ricciardo respectively.
