A coach driver took a reduced weekly rest period of 28 hours in week 1. By when must the 17-hour reduction (45h - 28h) be compensated, and how must it be taken?

1. It must be compensated within 6 months by taking extra 15-minute breaks during driving shifts
2. It must be compensated en bloc (in one single block attached to another rest period of at least 9 hours) before the end of the third week following the week in question
3. No compensation is required under passenger transport regulations
4. It is compensated automatically by the digital tachograph calculating a 5% speed reduction
