PRI Hoosier 500 officials have released the virtual race's 2025 rulebook and launched a new competitor portal for race participants.

The initial version of the event's governing rules remains consistent with past editions of the rulebook, dating back to the inaugural Open-Wheels 500 in 2019.

Nearly all race and qualifications procedures remain unchanged from the rulebook. This includes instructions on how the field will align in 11 rows of three during the formation laps for race day, as well as the rules governing the two-day qualifications process.

Open-Wheels Motorsports Sanctioning will continue as the governing body of the race, overseeing all competition-related aspects of the event.

The PRI Hoosier 500 has rolled out a new competitor portal, which will serve as the home to the latest rulebook, entrant schedule and FAQs. The portal will also host all competitor bulletins, meeting recordings and official session reports once on-track activity begins in December.

Registration for the 2025 PRI Hoosier 500 opens on October 1, running through November 3. As with years past, there is no fee for a driver to submit an entry to the PRI Hoosier 500.
