Residents of France who hold a non-EU, non-EEA license to drive may continue to use that license for up to one year after establishing residency, subject to certain conditions.
The relevant law may be found at www.legifrance.gouv.fr. A more user-friendly account of the rules is available at www.service-public.fr.
The definition of "residency" seems to cover any stay longer than 90 days, which is the time by which a non-EU, non-EEA spouse of an EU citizen must apply for a residence permit.
Consider now the case of a non-EU spouse of an EU (not French) citizen. They reside in the non-EU country for 8 months each year. When they arrive in France for a 4-month stay, they apply for a residence permit for the non-EU spouse. They leave, and six months later, the residence permit becomes invalid.
Does the invalidity of the residence permit cause the 12-month driver's license clock to reset, making it legal to continue to drive using the foreign license during subsequent periods of temporary residence in France?
