§395.2 Definitions.
...On duty time shall include:
(4) All time, other than driving time, in or upon any commercial motor vehicle except time spent resting in a sleeper berth;...
If all time spent in a CMV other than when RESTING in the sleeper berth is to be considered on-duty, does that mean that time spent engaged in sexual intercourse (obviously not resting, unless you are my ex-wife) in the sleeper must be considered on-duty? What line should the time spent on this activity be logged on? If I am in the sleeper but yet not resting and therefore on-duty, do I log this on Line 4? Does this now mean we have a line 6 to worry about? There are so many possibilities here. Does it depend on the actual acts being performed and how strenuous they are as to whether or not I am considered on-duty or not?
