How many hours of compensation time-off does a driver have left, if he has used 35 hours of a shortened weekly rest?

According to regulations, the regular weekly rest period for a driver is at least 45 hours. If a driver has taken a reduced rest period, in this case 35 hours, they must compensate for the missing time. The difference between the regular rest period and the one taken (45h - 35h = 10h) is the amount of compensation that the driver must take.
