Drivers' hours and rest periods: revision notes

Most lorry and coach work comes under the assimilated rules (previously called EU rules). Local bus routes of 50 km or less, and many smaller operations, use the GB domestic rules instead.

  • Driving: 9 hours a day, extendable to 10 hours twice a week; 56 hours a week; 90 hours in any two consecutive weeks.
  • Breaks: 45 minutes after no more than 4.5 hours of driving, or 15 minutes followed by 30 minutes.
  • Daily rest: 11 hours, reducible to 9 hours up to three times between weekly rests, or split as 3 hours then 9 hours.
  • Weekly rest: 45 hours regular, or 24 hours reduced (to be made up later). Start it no later than six 24-hour periods after the last one.

GB domestic rules: lorries 10 hours' driving and 11 hours' duty a day; buses and coaches 10 hours' driving, a 30-minute break after 5.5 hours' driving and 10 hours' daily rest.
