NASCAR Expands Cup Driver Eligibility In Lower Series For 2026

NASCAR will expand driver eligibility rules across its national series starting in 2026, allowing Cup Series drivers with three or more years of full-time experience to compete in more races in the lower divisions. Specifically, these drivers can enter up to 10 races in the O'Reilly Auto Parts Series (formerly the Xfinity Series) and 8 races in the Craftsman Truck Series, up from the current cap of 5 races in each. Despite this increase, Cup drivers will still be barred from participating in the regular-season finales, playoff races, and championship events for these lower series to preserve competitive integrity. Additionally, NASCAR is lowering the minimum age for O'Reilly Auto Parts Series participation on road courses and tracks 1.25 miles or shorter to 17 years old, down from 18, to facilitate a clearer development ladder for young talent. These adjustments aim to balance greater accessibility for experienced drivers with opportunities for emerging racers to develop their skills in a structured progression through the ranks. The changes reflect NASCAR's commitment to evolving its national series while maintaining competitive fairness and fostering young driver development.
