Vettel accused Hamilton of brake-testing him. The race stewards gave Vettel a 10-second stop-go penalty for dangerous driving. Formula 1 officials later stated that Hamilton had not brake-tested Vettel, and the FIA subsequently reviewed the incident before closing the matter after Vettel apologized.
