What are ‘papaya rules’ in Formula 1?

McLaren's 'papaya rules' serve as an internal code of conduct governing how team-mates Lando Norris and Oscar Piastri race each other on track. Named after the team's signature color, the directive permits the drivers to race hard and fair while strictly prohibiting any contact between the two cars, upholding equality since McLaren does not designate a primary driver.

Team principal Andrea Stella and CEO Zak Brown developed the guidelines alongside both drivers, emphasizing respectful racing without unnecessary risks. The policy faced scrutiny following collisions, including a late-lap incident during the 2026 Singapore Grand Prix sprint race where contact between the McLarens ended Piastri's race while Norris finished eighth.
