NASCAR states that the race leader (Montoya) has to be the first car across the starting line. Johnson got a huge jump on Montoya and refused to give up his position. Montoya also had the responsibility to speed up and be in the lead once the cars leave the restart zone. Johnson said Montoya wasn't driving fast enough.
NASCAR said it was an easy call. "He left early and he didn't give it back like we tell them all the time when that type of thing comes up," said Robin Pemberton, NASCAR's vice president for competition. "It's pretty cut and dried. You can look at the films and the restart zone and where the start was." Associated Press
