Sebastian Vettel has avoided a grid penalty for driving too slowly on an in-lap.
The Ferrari driver was summoned to the Stewards following the session, over an “alleged breach of Article 27.4 of the FIA Formula One Sporting Regulations".
As per the sporting regulations, drivers are required to stay above a minimum time between the two safety car lines during in-laps to ensure they don't become a danger to their fellow drivers.
For this weekend's event, drivers were notified to stay above 1:55.000 on their in-laps.
The Stewards noted that Vettel failed "to observe the Race Director’s instruction, document 2 (item 16.1), driving unnecessarily slowly on an in lap at 18:13 during qualifying.”
However the Stewards determined that Vettel was driving on heavily flat-spotted tyres that he damaged after locking up on a hot lap, which resulted in heavy vibrations.
"The driver stated he was on a push lap and, when coming into turn one, he heavily flat spotted both front tyres. He aborted the lap however the car was experiencing severe vibrations (as evidenced by the telemetry tabled in evidence).
“As a result, the driver could not maintain the speed required to meet the requirement to stay below the maximum time specified in Document 16 of 1.55.0s between the Safety Car lines.”
