Renault first put in place an initiative to encourage car pooling among employees in 1996. In July 2007, Renault reviewed and relaunched its car pooling service. Trialled at the Rueil and Lardy sites, the service proved to be a success and was extended to all French sites on June 1, 2008. The idea could now be extended to international sites. Each site forms groups based on where employees live, their working hours and whether they wish to be driver or passenger. Recent studies by insurance companies have shown that the practice of car pooling brings down the number of road accidents.
