Article 4
Maximum weekly working time Member States shall take the measures necessary to ensure that: (a) the average weekly working time may not exceed 48 hours. The maximum weekly working time may be extended to 60 hours only if, over four months, an average of 48 hours a week is not exceeded. The fourth and fifth subparagraphs of Article 6(1) of Regulation (EEC) No 3820/85 or, where necessary, the fourth subparagraph of Article 6(1) of the AETR Agreement shall take precedence over this Directive, in so far as the drivers concerned do not exceed an average working time of 48 hours a week over four months; (b) working time for different employers is the sum of the working hours. The employer shall ask the mobile worker concerned in writing for an account of time worked for another employer. The mobile worker shall provide such information in writing.
