Williams driver Pastor Maldonado and Toro Rosso rival Jean-Eric Vergne have escaped a penalty for their Brazilian Grand Prix collision.
The duo made contact on lap 65 of the 2013 Formula 1 season finale when Vergne dived down the inside of Maldonado at the Senna S.
The Williams was sent into a spin while the Toro Rosso continued to finish in 15th position, a place ahead of Maldonado.
The stewards deemed no driver was to blame for the accident.
"The stewards do not believe either driver of car #16 or car #18 were wholly or predominantly to blame for the incident," a statement said.
Maldonado, in his last race with Williams, said Vergne had been too optimistic with his move.
"It is a very hard place [to overtake] to understand it - I didn't see him," Maldonado said.
"From my point of view he was very optimistic, I was still ahead, and that is it. Nothing very special."
Vergne reckoned Maldonado should have left him space.
"I came up the inside of him at Turn 1 and he didn't leave me any room, so we touched and he spun," said the Frenchman.
