It's been a nervous wait for Fabian Coulthard and Brad Jones Racing after an incident under safety car threatened Coulthard's win in Race 15 at the Austin 400 in Texas.
There was an investigation into Coulthard illegally breaking away from the pack under the Pedders STP Chrysler 300C Safety Car – but as the investigation unfolded it was unearthed all top three drivers in that race failed to maintain speed under Safety Car.
So Coulthard and Red Bull Racing Australia's Craig Lowndes and Jamie Whincup have been penalised 30 Championship points apiece.
This doesn't change the Championship standings – Whincup, who won the second race of the day – still remains in the Championship lead, but with 1217 points, followed by Lowndes on 1075, Will Davison 1029, Coulthard 954 and Jason Bright 945. This puts Bright in a stronger position, bridging some of the gap to his teammate.
Post-race, Coulthard admitted the error, though he said there was a radio problem.
"I admit that I did pull away. I heard 'green flag' over the radio and then 'no, no, no'. I did the best I could but I tried to make it that I bunched up again to make it fair," Coulthard said.
"It was a radio communication problem within our team. We have had to change frequencies a few times over the weekend as I have been hearing two people on the radio."
