NASCAR has updated its rulebook so the Cup Series can welcome as many as 41 cars in cꩲase an Open Exemption Provision e💦ntry is granted.

The OEP system was announced before the start of the 2025 season, creating a new provisional starting berth for to♎p-class drivers with established credentials.

Four-time Indianapolis 500 winner H🦂elio Castroneves was able to race at Daytona after Trackhouse Racing applied for an OEP under his name and satisfied the required 90-day notice perio🦩d requirement.

Previously, the rules stated that if an OEP entry is grated, th🍒e size of the grid will be capped at 40 entries.

However, ahead of this week’s race at Las Vegas, NASCA🐻R issued a bulletin to Section 5.1.F under the “Entry Guidelines”, stating tha🐷t: “The Open Exemption Provisional will be applied only if more than 40 vehicles are qualifying for the Event. In that case, it will be applied regardless of the vehicle’s Qualifying position, and the starting field will be 41.”

The OEP entry would not be eligible for points or prize money a🏅s the 41st entry on the grid. However, if there are 40 or fewer cars on the grid, the OEP entry would both be awarded points and a share of the prize pot.

As was th🌊e case before, only one OEP entry is eligible per e🐓vent.

NASCAR further stated that it “has full discretion to deem certain E꧋vents ineligible for the OEP.𒉰”
