Parc fermé term defines F1 regulations for car modifications

Summary

Parc fermé, meaning 'closed park' in French, restricts Formula 1 teams from making significant changes to their cars after qualifying until the race begins. This rule ensures consistency between qualifying and race setups, with cars monitored by FIA technical delegates post-race. Recent modifications to the 2026 regulations include provisions for Rain Hazard adjustments and revised rules for Sprint weekends, which involve a two-part parc fermé process. Teams can perform limited maintenance tasks under parc fermé, but major alterations are prohibited to maintain competition integrity.
