Under 49 CFR 395.3(c), a driver of a property-carrying vehicle may restart the 7-day or 8-day period by taking 34 or more consecutive hours off duty. Sleeper-berth time counts as off duty for the restart. When the 34 hours are done, your 60/70-hour total goes back to zero.
The restart is optional. If the days rolling off your 70-hour recap give you enough hours, you can keep running without one.
The 2013 restart limits are not in force
A 2013 rule required every restart to include two periods from 1 a.m. to 5 a.m. and allowed only one restart per 168 hours. Congress suspended those provisions in December 2014, and later appropriations language kept them out of effect. Today a restart is simply 34 consecutive hours off duty, at any time of day, as often as you need one.
Common mistakes
- Logging a short on-duty task (a fuel stop or moving the truck in the yard) during the 34 hours. That breaks the restart and the clock starts over.
- Mixing time zones. Your logs use your home terminal's time zone, not local time where you parked.
- Assuming a restart also resets the 11-hour and 14-hour limits for good. Those reset after any 10 consecutive hours off duty; the restart is about the 60/70-hour limit.
Frequently asked questions
How long is a 34-hour restart?
34 consecutive hours off duty or in the sleeper berth. If you go off duty at 6:00 p.m. on Monday, the restart is complete at 4:00 a.m. on Wednesday.
Does a 34-hour restart need two nights from 1 a.m. to 5 a.m.?
No. That 2013 requirement and the once-a-week limit were suspended in December 2014 and are not in effect. A restart is 34 consecutive hours off duty, at any time.
Can I take a 34-hour restart more than once a week?
Yes. There is currently no limit on how often you take a restart, as long as each one is 34 consecutive hours off duty.
Does sleeper-berth time count toward the 34-hour restart?
Yes. Off-duty time and sleeper-berth time both count. Any on-duty time, even a few minutes, breaks the restart.
Do I have to take a 34-hour restart?
No. It is optional. Without one, you get hours back as old days roll off your 7-day or 8-day period.
