FIA Grade 1 circuits only (homologation required); 23+ circuits on the 2026 calendar; Pit lane speed limit: 80 km/h (race), enforced by car-side limiter; Track-edge kerbs, sausage kerbs, and run-off areas defined per circuit homologation
Why people argue about this
People often assume that the pit lane speed limit of 80 km/h applies universally across all circuits, forgetting that it's only enforced at Grade 1 circuits where Section 3 requires homologation for the playing area. They overlook the distinction between Grade 1 and other circuit types, leading to misunderstandings about which rules apply where.
