What are the limits on working time under the Road Transport (Working Time) Regulations 2005?

For the purposes of the Road Transport (Working Time) Regulations 2005 (SI 2005/639) the working time of mobile workers is restricted to an average of 48 hours a week over the relevant reference period, and must not exceed 60 hours in any week. No opt-out from the average 48-hour week is permitted. The working time of a mobile worker who performs night work must not exceed 10 hours in any 24-hour period. Night work is any work performed during night time, which is defined as the period between midnight and 4 am for goods vehicles and the period between 1 am and 5 am for passenger vehicles. The night work limit can be exceeded only where this is permitted by a relevant agreement.
