Stewart intentionally spun Brian Vickers last week at Sonoma because he felt Vickers was blocking him during the race. Vickers retaliated later by wrecking Stewart, who had a car capable of contending for the win but finished 39th.
It dropped him to 12th in the Chase for the Sprint Cup championship standings.
"I am drawing a line in the sand and the next guy that blocks me, he is going to also suffer the same fate," Stewart said at Daytona International Speedway.
He also upped the ante, stating in a calm manner that he'd wreck the next driver enough to ensure he won't be able to come back and retaliate against Stewart.
"It doesn't matter who it is," he said. "I'll make sure that when I do it the next time that the guy doesn't have the opportunity to come back and wreck me."
His stance seems to be excessive, especially since Stewart is on the bubble of making the Chase with only 10 races left to qualify for the 12-driver field. Under new qualifying rules, only the top 10 drivers are guaranteed a Chase berth.
The other two spots will go to drivers ranked between 11th and 20th who have the most wins. Stewart is winless this season.
