A rolling/floating means as you move to the next day without a 34/36 hour reset, every day you regain the hours from the beginning of the cycle. For the 60/7 cycle, this means that on the Day 8, the driver would regain on-duty hours that were spent 8 days back as newly available driving hours. In other words, the current day (Day 8) would be the newest day of your 7-day period and the hours that been used eight days ago would drop out of the calculation. Same framework applies to 70/8 cycle, on the Day 9 the driver will regain hours that were spent 9 days back.

Let’s illustrate with an example:

On Tuesday Day 1, the driver began a new 70/8 cycle after having 34-hour reset. 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 11 hours of on-duty hours. The 8 hours he regained from Day 1, plus the 3 hours he still had remaining in his 70-hour cycle, gave him a total of 11 hours available as an on-duty hours, during which he can drive.

Limitations:

1. You cannot to drive a commercial motor vehicle after you’ve been on duty for 70 hours in any 8 consecutive days. You can only drive until the 70-hour limit is dropped. Take 34 hours reset to regain the hours. Same condition applies to 60/7 cycle and Canadian Cycles – Cycle 1 and 2.
2. In Canada, a driver needs to take at least 24 consecutive hours of off-duty time in the preceding 14 days before continuing his driving.
