J-BONE:
When driving on Domestic hours rules and one day of the week driving under EU rules the EU rules for the whole week must take precedence.
My question is how many weekends are effected by EU weekly rest set around the single day I drive on EU rules?
If you only do 1 days work in-scope of EU regulations it will only affect the 1 weekly rest period for that week
For example,
I drive 6 days a week every week on domestic rules but if then I’m then asked to drive a vehicle on EU rules for a day or 2 then back on domestic rules, am I legal to drive on those 1 or 2 days considering I’ve had no recent regular weekend rest?
What then should be my next few weekend rest periods?
If you drive in-scope of EU regulations on any day you must comply with the EU regulations daily rest requirement on the days that you drive in-scope of EU regulations.
In any week that you drive in-scope of EU regulations, even if it’s just 1 day, you must comply with the EU regulations weekly rest requirement.
Any work, including driving, done on domestic regulations counts as other work for the EU regulations.
Example.
Lets say you start work at 08:00 Monday on domestic regulations and stay on domestic regulations until and including Friday, on Saturday you work in-scope of EU regulations, because the work done on domestic regulations counts as other work for the EU regulations you must start a weekly rest period no later than 08:00 Sunday (144 hours from when you started on Monday).
Example.
Lets say you start work at 08:00 Monday on domestic regulations then work in-scope of EU regulations on Wednesday and Thursday, then you go back on domestic regulations on Friday and Saturday, again because you’ve worked in-scope of EU regulations you must start a weekly rest period no later than 08:00 Sunday (144 hours from when you started on Monday).
Example.
You work all week Monday to Sunday in week 1 on domestic regulations and finish work at 18:00 Sunday evening, you then start work at 06:00 Monday (week2) on domestic regulations, you work on domestic regulations most of the week but drive in-scope of EU regulations on one day.
You should start a weekly rest period no later than 144 hours from when you started work on Monday, so you would need to start a weekly rest period no later than 06:00 Sunday (week 2).
The fact that you worked 7 consecutive days in week 1 is irrelevant because you never drove in-scope of EU regulations.
In any week that you do not drive in-scope of EU regulations you do not have to have a weekly rest period, but if you do any work in-scope of EU regulations in a week you should have a weekly rest period for that week, if you do any work in-scope of EU regulations in 2 consecutive weeks you should comply with the weekly rest requirements i.e. have at-least 1 regular and 1 reduced weekly rest period in the 2 weeks.
