The Revised Hours-Of-Service Regulations
Time logged as “off-duty” is not
counted in calculating “on-duty”
time.
•Weekly Break: At least 34 consecu-
tive hours (1 day 10 hours).
•Restart: A break of 34 consecutive
hours “restarts” the weekly cycle.
•Sleeper Berth: Among the changes
in the 2005 rules, perhaps the most
significant – and most confusing –
relates to the split-sleeper option.
That is the option that allows a
driver to split his/her required 10
consecutive hours of rest into two
separate, non-consecutive breaks.
Though the split-sleeper option will
still be an option after October 1st,
for both teams and individual driv-
ers, the requirements will change
significantly – so much, in fact, that
many are wondering if they should
continue using the option at all.
Under the 2003 rules, a driver
could split his/her time into any combi-
nation of two breaks that added up to
10 hours, so long as the breaks were at
least 2 hours long. These breaks had to
be spent entirely in the berth, but they
were excluded from the 14-hour limit.
Under the 2005 rules, you still
need two breaks that add up to 10
hours. But, recognizing that drivers
need 7 to 8 hours of continuous sleep
to beat fatigue, the rules require one
of the two breaks to be at least 8 con-
tinuous hours. Like the 2003 rules, this
break must be spent entirely in the
sleeper berth, and it will still be ex-
cluded from the 14-hour limit.
The other break must be at least
2 hours long (this is so that the driver
gets the required 10 total hours of
rest), but this break can be spent off
duty, in the sleeper berth, or any com-
bination of the two. In addition, this
shorter break is always included in the
14-hour limit, no matter where it is
spent (i.e., it always counts against the
driver, even if it is spent in the sleeper
berth). Because one of the two breaks
will count against the driver’s 14-hour
limit, the new rules change the way you
calculate available hours after a
break. As under the 2003 rules, once
you have completed two qualifying rest
breaks that add up to 10 hours (one
being at least 8 hours in a sleeper
berth), you do not gain back a full 11
driving hours and 14 on-duty hours.
Rather, following the second rest break,
hours available under the 11 and 14
hour rules must be recalculated from
the end of the first of the two breaks.
Examples: Suppose driver Smith
takes 10 hours off and starts driving. He
drives for 6 hours and then decides to
take a 2-hour nap. Those 2 hours will
count against his 14 hour limit no matter
where he takes them (off duty and/or
sleeper). After his nap, he drives for his
remaining 5 hours and is then at hour 13
