- Truck Series race limit for Cup drivers increases from five to eight

NASCAR confirms expanded cross-series eligibility for 2026, broadening Cup driver participation in the Xfinity and Truck Series. The changes target competitive balance and talent development.
Cup drivers with three or more full Cup seasons may run up to 10 Xfinity races, doubling the previous five-race cap.
In Trucks, the limit rises from five to eight events. Xfinity bans remain for playoffs, cutoff rounds, and the championship finale.
Cup drivers can run 10 Xfinity races and eight Truck events starting in 2026.
The reset responds to long-running concerns about star influence in development series. It protects title integrity while creating more benchmarking for regulars.
Kyle Busch’s prolific lower-tier success previously prompted restrictions, widely labeled the “Kyle Busch rule.”
In 2025, Cup drivers won five Xfinity races via Kyle Larson, William Byron, Daniel Suarez, and Shane van Gisbergen.
They added three Truck victories, led by Kyle Busch, Kyle Larson, and Carson Hocevar. Ross Chastain maximized prior limits across both series.
Cup drivers remain barred from Xfinity playoff, cutoff, and championship races.
NASCAR also lowers the minimum age to 17 for road courses and ovals of 1.25 miles or shorter, opening earlier pathways for prospects.
Tracks longer than 1.25 miles still require drivers to be at least 18, preserving a staged safety progression.
Teams will recalibrate programs, mixing veteran entries for event profile and data with targeted outings for rising drivers.
The expanded participation should sharpen racecraft for regulars by raising the benchmark without distorting championship arcs.
The 2026 campaign will reveal the balance achieved between increased star presence and accelerated development.
Minimum age drops to 17 for short tracks and road courses; 18+ remains for larger ovals.
