Recital 8

(8)In its judgment in Case C-394/92 Michielsen and Geybels Transport Service ⁵ , the Court of Justice provided a definition of the term ‘daily working period’, and the control authorities should read the provisions of this Regulation in the light of that definition. The ‘daily working period’ commences at the time when the driver switches on the tachograph following a weekly or daily rest period, or, if the daily rest is divided into separate periods, following a rest period of at least nine hours’ duration. It ends at the beginning of a daily rest period or, if the daily rest is divided into separate periods, at the beginning of a rest period extending over a minimum of nine consecutive hours.
