Travel is now authorised without a certificate of special dispensation, within the limits of the department of residence or within a radius of 100 km around the place of domicile, whichever is greater. Proof of address must be presented in the event of an inspection (e.g. electricity, water or telephone bill, tax notice). Beyond 100 km outside one’s department, only trips for imperative reasons (professional or family-related) are authorised but require a new certificate.
