Triple world champion Nelson Piquet lost his driver's license in Brazil last month, according to reports. The news agency Globo News said the 54-year-old, whose son Piquet Jr tests for the Renault team, lost all of his demerit points due to a range of traffic infringements, including speeding. Piquet reportedly did not contest the cancellation of his credential.

Brazilian authorities would not however confirm the news, or answer speculation that the final infringement was a speeding breach of more than 50kph above the legal limit.

To regain his license, former Brabham and Williams racer Piquet began a driving reform programme in the central capital Brasilia on Monday.

He will be accompanied throughout the eight days of classes by his wife Viviane, whose license was confiscated for bad driving, the newspaper O Globo added. (GMM)
