Formula One’s governing body, the FIA, has decided to take no further action over multiple DRS infringements during the Chinese Grand Prix.
Following an accident involving Esteban Gutierrez and Adrian Sutil, yellow flags were waved at the bottom of the back straight on the run down to turn 14, warning drivers to slow down. Under these conditions, drivers are forbidden from using DRS, yet it appears that many failed to adhere to this.
Sebastian Vettel, Mark Webber, Kimi Raikkonen, Valtteri Bottas, Daniel Ricciardo and Max Chilton were all summoned to the stewards’ office after the race, but the decision has been taken to issue no penalties.
In the opening two races, the FIA reported problems with the telemetry linking race control and the cars on track. Usually, under yellow flag conditions, DRS would be automatically disabled. However, assuming that the issue has arisen once again this weekend, the FIA may have decided to be lenient with the drivers.
The telemetry issue has come about after the FIA switched supplier during the off-season, but once these teething problems are resolved we can expect communications between race control and the teams to return to normal.
