Following the death of Kevin Ward, Jr., NASCAR announced a new rule Friday, saying drivers are no longer allowed to get out of their vehicles while on the track.
The rule says, "at no time should a driver or crew member approach any portion of the racing surface or apron" or "approach another moving vehicle."
This new rule comes just about a week after the accident that killed Ward.
Ward left his vehicle during a race on Saturday after a wreck involving fellow driver Tony Stewart. Ward then stormed onto the track while cars flew by him. He even threw his helmet at a moving car.
While he was on the track, Stewart struck and killed him with his vehicle. Stewart has not been charged in the ongoing investigation.
