The association didn't exactly commit to if or how fans will be allowed to keep displaying the symbol, mentioning fans have a right to freedom of expression. But HLN reports:
"They're going to ensure that that flag doesn't show up at any of their events including in the campgrounds and infields."
As USA Today points out, "Racetracks are private property, and it's within a business's discretion to disallow certain symbols." So if NASCAR wanted to outright ban them, they ideally could've done so by now.
"Their fan base kind of having a traditionalistic, idealistic approach to the Confederate flag and NASCAR not wanting to step on their toes because of that. I think NASCAR should take a strong stance," Fox Business reports.
Local newspaper The Press Democrat spotted one person wearing the Confederate flag at practice trials over the weekend, but the Sonoma Raceway says it doesn't have a ban on what flags can be displayed.
If NASCAR does want to place a firm ban on the flag, policing it may also be a problem, as races can draw nearly 100,000 fans on average per event.
Last week, Speedway Motorsports Incorporated released a statement saying third-party vendors are not allowed to sell Confederate flags at Sunday's race.
