Formula 1 stewards have opted not to take further action regarding the multi-car incident at the start of the British Grand Prix described by Fernando Alonso as "a big mess".
Daniel Ricciardo's Red Bull made contact with Romain Grosjean's Lotus when the Australian dived down the inside of the Frenchman at Village on the opening lap.
That pushed Grosjean into team-mate Pastor Maldonado, sending the Venezuelan briefly airborne and forcing both drivers into retirement.
Alonso spun his McLaren-Honda on the exit of the corner in avoidance of the two Lotus drivers, and collected the left-rear of team-mate Jenson Button, ending the Briton's race immediately.
A statement from the stewards read: "After hearing from all the drivers involved in the Turn 3 incident at the start of the race, it was decided that no driver was wholly or predominately to blame."
Alonso went on to score his first point for McLaren-Honda in 10th but was unhappy after the race, labelling the incident "unbelievable".
"They [the Lotus team-mates] touched each other, and then to avoid them I had half a spin, until I touched Jenson and he retired," he explained.
"So one McLaren out, both Lotuses out. There definitely was no common sense at that corner."
Red Bull team boss Christian Horner said the collision did not require any action.
"It was a racing incident," he said. "When racing in the midfield like that it gets pretty cosy through the first few turns."
Ricciardo ultimately retired with an engine problem but Grosjean said the Red Bull man had been "a bit optimistic" at the start.
He added: "[He] locked up and went straight. There was a Sauber outside me and Daniel so I couldn't turn in.
"[He] touched me, I then touched the Sauber which meant my front wing and front tyres were gone and that's why my car flicked to the left and Pastor was there.
"That was it. Turn 3 is always a bit of a tricky one and when you're between 10th and 15th there's always more risk."
