Carlos Sainz Jr had a big accident at Sochi in the free practice session for the Russian GP. The Spanish driver hit the wall at high speed in Turn 12 and the Toro Rosso then ploughed on into two rows of Tec-pro barriers at Turn 13. The car went under the water-filled plastic barriers but seems to have stopped before any major impact with the metal barriers behind them. The team reported that the driver was conscious but it is not known whether he has any injuries. The accident does not appear to have been a car failure.
