SHANGHAI, Oct. 1 (Xinhua) -- Honda's Rubens Barrichello retained his third place on the grid, becoming the first driver to benefit from a change in the rules that will not penalize drivers who impede a rival inadvertently.
The Brazilian had been investigated following protests made by McLaren, but was judged to have not been given the sufficient blue flag warnings when he exited the pit lane directly in front of Pedro de la Rosa.
"Enquiries show that as a result of a system fault, the blue lights at pit exit were not illuminated to indicate the presence of a car on the pit straight, nor was the blue flag waved at pit exit," stewards said in a statement.
A revision in the blocking rules came into force from the Chinese Grand Prix as a result of the outcry following Fernando Alonso's demotion on the grid for impeding Felipe Massa at Monza.
As a result Barrichello was able to retain his third place on the grid.
"I had to run wide to avoid a collision and it was about three corners before I was able to get past by which point my tyres had cooled off," he said. Enditem
