Move over yellow line. The latest concern for Sprint Cup drivers are the double red lines.
With no out of bounds area at the bottom of the track at Lowe's Motor Speedway, drivers weren't worried about a similar finish to last week at Talladega, when Tony Stewart was awarded the win after Regan Smith's pass below the yellow line was ruled illegal.
Instead, the drivers meeting before Saturday's Bank of America 500 included numerous questions about restarts after Kyle Busch drew criticism a night earlier during the Nationwide race.
Drivers accused Busch of brake-checking before the green flag and causing bunching and contact between cars in the back of the field. Busch said he was waiting for second-place driver Jeff Burton to get close enough so he didn't gain momentum from hanging back.

Jeff Gordon, Elliott Sadler and Busch all asked questions about the rule. NASCAR president Mike Helton told drivers the leader must restart the race somewhere between the double red lines in the frontstretch and could not brake-check after the pace car leaves the track.
"Restarting the race is no rocket-science deal," Helton said.
Helton said Busch did nothing wrong in Friday's race, and NASCAR officials seemed eager to end the lengthy discussion.
"You all know how to do this," race director David Hoots said. "Don't reinvent the wheel."
