Abstract: A method for monitoring extra off-duty time intervals of a driver includes: obtaining on-duty time intervals and off-duty time intervals of a driver; and scanning the off-duty time intervals to identify extra off-duty time intervals having a length more than a second minimum length and less than a first minimum length, any identified extra off-duty time intervals being subtracted from a predefined threshold. If the threshold is greater than 0, a workshift reset time interval is analyzed and it is determined if the workshift reset time interval includes an extra off-duty time interval, which cannot be used as workshift reset time interval. Subsequently the analyzed extra off-duty time intervals are subtracted from the threshold. If the threshold is greater than 0, the workshift reset time interval is analyzed and, the workshift reset time interval is, at least partly, shifted from today to tomorrow to create extra off-duty time interval today.
