Lewis Hamilton is one of four Formula 1 drivers set to be investigated by stewards after Qatar Grand Prix qualifying.
Hamilton, Yuki Tsunoda, Liam Lawson and Oscar Piastri were all noted for failing to follow race director Niels Wittich's instructions regarding the minimum lap-time between the two Safety Car lines.
Set at 1:46.0, drivers must not go slower than this to avoid a potentially dangerous build-up of traffic, especially in Q1 when all 20 cars are on track.
However, there are exceptions in place for when drivers go slower than the time allowed if they were getting out of the way of impeding other drivers, as happened to Carlos Sainz and Charles Leclerc at Monza.
Hamilton, Tsunoda and Piastri all made it through to Q2 at Lusail, while Lawson was eliminated in Q1.
