This excellent explanation of the DOT Hours of Service 34 hour Restart Rule was cut n pasted from #244 of The Teamster News Digest. I also posted it onto the Freight Forum.
Drivers who are subject to the new federal hours-of-service rules now
have the option of restarting their 60/70-hour calculation after
taking 34 consecutive hours off duty (the so-called "34-hour
restart"). If your drivers are taking advantage of that option, you
need to make sure they are consistent when filling out their log
recaps and monthly summary sheets, and that they are using the
restart option appropriately.
The 34-hour restart provision is allowed for anyone operating a
property-carrying commercial motor vehicle (over 10,001 pounds or
placarded for hazardous materials) in interstate commerce. After such
a driver obtains 34 consecutive hours of rest, his or her on-duty
hours accumulated toward the 60- or 70-hour limit fall to zero (0).
In other words, after taking 34 consecutive hours off duty (and/or in
a sleeper berth), the driver will have 60 or 70 hours available again
(refer to 49 CFR 395.3(b) and ©).
But watch out - the restart option cannot be used if a driver has
accumulated more than 60/70 hours in 7/8 days. If a driver has
accumulated more than the limit (whether there was a 60/70-hour rule
violation or not), he or she must continue to log as if the 34-hour
restart were not an option.
Once the driver's accumulated hours fall to or below the 60/70-hour
limit, then the 34-hour off-duty period can begin.
The Log Summary Sheet
The log summary sheet, also known as a monthly log summary and found
on the inside cover of most Keller logbooks, provides a simple way to
track a driver's accumulated on-duty hours for a month-long period.
Drivers enter their on-duty hours for each day and then calculate how
many hours are available tomorrow.When completing the log summary,
your drivers should all be on the same page when it comes to
recording a 34-hour restart.
Keep in mind, however, that there is no "right" or "wrong" way to
complete the summary, as there are no regulations governing or
requiring its use.
As discussed above, if eligible, a driver who has completed 34
consecutive hours off duty has 60 or 70 hours available again.
Therefore, after a restart there is no need to consider the hours
accumulated before the 34-hour period began.
In the log summary, then, the "hours on duty last 6/7/8 days" can
appropriately be recorded as "0" (zero), and the "hours available
tomorrow" would be "60" or "70".For example, suppose a driver using
the 60-hour rule takes the weekend off, completes the 34-hour period
on Sunday, and works 10 hours on Monday.
In the summary for Sunday, the driver can enter "0" for "Total hours
on duty last 6 days" and "Total hours on duty last 7 days," because
the hours worked before Saturday are no longer considered. The "Hours
available tomorrow" can be entered as "60." Then, on Monday, the
driver would enter "10" as the "Total hours on duty last 6 days"
and "Total hours on duty last 7 days," and the "Hours available
tomorrow" becomes 50, and so on.
After the restart, make sure your drivers do not continue to add in
the hours worked before the restart began! Doing so could only
confuse the driver, the log auditor, and (worst of all) a DOT
inspector.To highlight the fact that the restart option has been
used, you may want to consider having drivers write "restart" or "34
off" in the margin of the summary sheet whenever they use the restart
The "recap" appears on the side of many drivers' log sheets, and
serves a similar function as the monthly summary - it records a
driver's total on-duty hours for the day and the hours available
As with the log summary sheet, once a driver has 34 hours off duty,
he or she no longer has to consider the hours accumulated before the
34-hour period began. The "Hours available tomorrow" becomes 60 or 70
(minus any on-duty time performed during that day), and the "hours on
duty last 6/7/8 days" becomes zero.Again, make sure your drivers do
not continue to add in the hours worked before the restart began.
Drivers could write "restart" or "34 off" in the recap or Remarks
area of the log to indicate that they used the restart option. As
with the monthly summary, there is no "right" or "wrong" way to
complete the recap, as there are no regulations governing its use.
However, making sure your drivers are consistent in the way they
record the 34-hour restart on the recap and log summary sheet will
lead to fewer headaches for them, your auditors, and enforcement
