NASCAR announced Wednesday that it has updated the open exemption provisional rule, which was used to secure a starting spot for Helio Castroneves in the Daytona 500.
Teams still must request the provisional 90 days before an event.
Now, if there are more than 40 cars, then the field will automatically expand to 41 cars and the team requesting the provisional muse use it regardless of where it qualifies.
