If you’re familiar with the trucking industry, you’ve most likely heard of the 60-hour/7-day or 70-hour/8-day cycle. The 60-hour/7-day cycle limits a driver to 60 hours of on-duty time during a 7-day window, while the 70-hour/8-day cycle limits a driver to 70 hours of on-duty time over an 8-day period.
The 8-day and 7-day windows are often referred to as a “rolling” time frames, but what does this mean?
A “rolling” window simply means that as you advance to the next day, you regain hours from the beginning of the cycle. For the 60/7 cycle, this means that as a driver advances to what would be considered Day 8, he or she would recuperate on-duty hours that were spent 8 days back as newly available driving hours. The same method is applied to the 70/8 cycle -as a driver advances to what would be considered Day 9, he or she will regain available driving hours that were spent 9 days back.
Can I stay on-duty (non-driving)?
Yes, a driver can remain on-duty and perform other tasks outside of driving (regardless of which cycle is followed), but those additional on-duty hours must be taken into account when assessing an individual’s available driving hours during his or her current cycle window.
Let’s clarify with an example:
On Tuesday, the driver began a new 70/8 cycle after completing the requirements for a 34-hour restart. His on-duty hours, both driving and non-driving, are subtracted every day from the 70 hours allotted over the 8-day window. On Wednesday, Day 9, the driver regained on-duty hours used on Day 1. The 8 hours he regained, plus the 4 hours he still had remaining in his 70-hour cycle, gave him a total of 12 available, on-duty hours, during which he can drive on Wednesday.
Try electronic logging as an alternative to paper-logs. You can download a free electronic logbook from the app store. Many of these mobile logbooks automatically calculate remaining hours of service and alert drivers to potential violations.
