Working 15 hours daily for 4 days. Is it possible?

You can have 3 reduced daily rest periods between weekly rest periods and as you’ve had 3 already you cannot legally have another one until after a weekly rest period.

Have I gotten the 10 hour drives and reduced rests the wrong way round? I know one resets on the sunday night whilst the other resets after a weekly rest.

To be fair, working monday to friday and having the weekend off means it doesnt matter, but it’s useful to know.

Yes you have got them the wrong way round, you can have 3 reduced daily rest periods between weekly rest periods and you can have 2 extended daily driving periods (10 hour drives) per week.
