Mixed EU/AETR and GB domestic driving
Many drivers spend some of their time driving under one set of rules and some under another set, perhaps even on the same day. If you work partly under EU/AETR rules and partly under GB domestic rules during a day or a week, the following points must be considered:
The time you spend driving or on duty under EU/AETR rules cannot count as a break or rest period under GB domestic rules.
Driving and other duty under GB domestic rules (including non-driving work in another employment) count as other work but not as a break or rest period under EU/AETR rules.
Driving and other duty under EU/AETR rules count towards the driving and duty limits under the GB domestic rules.
When driving under each set of rules you must comply with the requirements of the rules being driven under e.g. the daily rest provisions for domestic and the daily and weekly rest requirements for EU/AETR driving.
The GB domestic limit (a maximum of 10 hours of driving a day) must always be obeyed. But at any time when you are actually driving under the EU/AETR rules you must obey all the rules on EU/AETR driving limits.
Other duty limits
The GB domestic limit (i.e. no more than 16 hours on duty for drivers of passenger vehicles) must always be obeyed. But when working under EU/AETR rules you must also obey all the rules on breaks, daily rest (only on those days when actually driving) and weekly rest.
Rest periods and breaks
Again, you must always obey the EU/AETR rules on rest periods and breaks on days and weeks when driving in scope of EU/AETR rules is carried out.
Where a driver works under GB domestic rules in week 1 and the EU/AETR rules in the second week, the weekly rest required in week 2 must start no later than 144 hours following the commencement of duty on or after 00.00 on Monday.
During a week in which the in-scope driving has taken place, any previous work (including out-of-scope driving in that week) would have to be recorded as 'other work' on a tachograph chart, printout or a manual input facility of a digital tachograph.
When driving a vehicle subject to EU or AETR rules, a driver is required to produce on request tachograph records (including other work records described above) for the current day and the previous 28 calendar days when he has driven in scope of the EU/AETR rules in the relevant week
