Carlos Sainz received a grid penalty for the Azerbaijan Grand Prix due to a violation of yellow flag regulations.

Williams racer Carlos Sainz has been dealt a five-place grid penalty for the Azerbaijan GP in Baku on Saturday due to exceeding the speed limit under yellow flags during qualifying.

As Q3 concluded, Sainz was the final driver among three to be affected by a yellow flag at Turn 3, prompted by Lando Norris, who had veered off into the escape area. When Sainz neared the braking zone, Norris had already rejoined the track, yet the Spaniard still needed to adhere to the local yellow flag into the sharp left turn.

Sainz received a notification from his race engineer about the yellow flag ahead and was advised to ease off slightly into the corner. However, the FIA's race stewards concluded that the Williams driver only reduced his speed in one of the two impacted marshal sectors, specifically four and five, leading to the five-place grid penalty.

Sainz contended that he had adequately decelerated throughout the entire section, but despite achieving his quickest mini sector time of the session in Marshalling Sector 4, the stewards disagreed with his reasoning.

"SAI clarified that he aimed to show a speed reduction across the entire Yellow area," the stewards stated in their report. "He mentioned that he felt it unnecessary to slow down on the straight and instead intended to display his reaction when approaching and exiting Turn 3.

"He regarded this as a 'global lift' covering the consecutive Yellow sectors. He further noted that the car which initially caused the Yellow was no longer in the run-off area and he anticipated the Yellow Flags would be retracted.

"The Stewards did not accept this interpretation. In cases where consecutive marshalling sectors are under Yellow Flag conditions, a driver must clearly demonstrate a substantial response to reduce speed in each individual Yellow marshalling sector. A reduction in a later sector cannot retrospectively fulfill the requirement for the preceding Yellow sector."

The stewards further elaborated: "The obligation is not contingent upon the driver’s personal evaluation of whether the original hazard is still present in a specific section of the Yellow sector. The telemetry distinctly indicated that SAI’s reaction to the Yellow occurred solely in Marshalling Sector 5. There was no significant reduction in speed in Marshalling Sector 4 that could realistically be seen as a response to the Yellow. In fact, SAI clocked his fastest time of the session in Marshalling Sector 4."

Consequently, Sainz has been relegated five places, dropping from ninth to 14th on the starting grid for Saturday. This penalty negates some of the progress Williams had made to get back into Q3, having developed a completely new, lighter chassis and a revamped floor for the Baku race.
