Jarno Trulli was lucky to escape uninjured from a violent accident during Sunday's British Grand Prix at Silverstone.

Exiting the high speed Bridge corner, Trulli's Renault suffered a suspected suspension failure sending the Italian spinning off to the right. After a huge rearward impact with the barrier that destroyed the back of the car, Trulli rolled once before coming to rest in the gravel trap.

Despite the violent nature of the accident, Trulli was able to climb from the car and, after being taken to the medical centre as a precaution, said he felt fine.

"First of all, I want to let everybody know that I am okay," he said at the circuit. "It was a big accident but I gave the marshals the thumbs up straight away. Everything happened very quickly, but I think it was a rear suspension failure.

"However, we will only be able to confirm that when we get back to the factory. Even before the crash, though, things were not going well. I was very heavy in the first two stints but even taking that into account, I was struggling to be quick. The car was tricky to drive, and I had trouble holding position."

Trulli also told Radio Silverstone after the incident that he thought it "looked much worse than it actually was" and both team boss Flavio Briatore and chief engineer Pat Symonds were relieved that Trulli had escaped uninjured, with Symonds also believing that a suspension fault may have been to blame.

"This was a very disappointing result for the team," Symonds said after Fernando Alonso could only bring the other car home tenth. "Jarno did not seem to have the speed we expected, though we do not know why at this stage. The important thing, however, is that he was not injured in his accident, which we believe may have been the result of a rear suspension failure."
