Last week you drove 56 hours. This week you have already driven 30 hours. How much driving remains this week under the 561/2006 fortnightly cap?

1. 26 hours, because 56 minus 30 is 26
2. 4 hours, because 90 minus 56 minus 30 is 4
3. 10 hours, because you may still take two 10-hour days
4. No driving, because 56 hours last week already used the fortnight
