F1 scrutineering explained
How FIA technical delegates check cars, systems and samples for regulatory compliance.
Quick answer
Scrutineering is the FIA inspection process before, during and after a race weekend. It can include dimensions, mass, software, components, tyres, fuel and targeted checks selected by technical officials.
Initial checks
Teams submit declarations and cars undergo the required pre-competition processes. Seals and component identities help officials track regulated assemblies.
Targeted inspection
The FIA can select cars and technical areas for detailed examination, using physical measurement, data review, samples and teardown where necessary.
After the flag
Results remain provisional until technical and sporting checks are complete. A car can finish on the podium and later be excluded for a measured breach.
