NASCAR determined its penalties for the manipulation at the end of Sunday’s race at Martinsville Speedway based on the last time it occurred, but it wanted to go further. And the series vowed to continue to ramp up its punishment if things don’t change.

Nine individuals from three teams were suspended on Tuesday. The crew chiefs and drivers were fined a total of $600,000, and points were docked. NASCAR was reacting to William Byron and Christopher Bell, who were helping their manufacturer teammates advance into the Championship 4.

The most recent race manipulation penalty was for Stewart-Haas Racing’s No. 41 team for helping teammate Chase Briscoe at the Charlotte Roval. The penalties were points, fines, and suspensions, as NASCAR did this time around for Richard Childress Racing, Trackhouse Racing, and 23XI Racing.
