NASCAR has introduced a new restriction that limits drivers who participate in more than one series during a single event, a move intended to preserve competitive balance and keep the focus on the core series.
The policy will curb the number of multi‑series entries for the upcoming street race in San Diego, an event that has attracted considerable attention for its unique urban setting.
Nevertheless, the series will make an exception for Richard Childress Racing’s No. 33 entry, allowing Austin Hill to take the wheel despite his full‑time schedule in the O’Reilly Auto Parts Series.
Hill, who already competes week in and week out in the NASCAR Cup Series, will now add a second commitment to his calendar, a decision that reflects both his rising profile and the team’s need for continuity after the recent loss of Kyle Busch.
The timing of the exception is poignant; the No. 33 team seeks stability following the tragic passing of Kyle Busch, a driver who had been a central figure for the organization.
Adding to the intrigue, veteran Jimmie Johnson is also slated to compete in multiple series during the San Diego weekend, further blurring the line between traditional series boundaries.
