How to Calculate DOT 70 hours Recap

In this article, I aim to elucidate the concept of the 70-hour recap window, which assists drivers in managing their electronic logs after reaching the 70-hour limit within a week. Prior to delving into this, I’ll provide a brief overview of how drivers can utilize their recap hours and the timeframe within which they can do so.

Calculating recap hours involves utilizing a duty cycle that allows for working 70 hours within an eight-day period. These hours enable longer runs without necessitating a 34-hour reset, essentially allowing hours to roll over continuously.

For truck drivers, there’s a 70-hour working window over eight days. Upon completing the eighth day, one can opt for a 34-hour reset or continue running on recap hours. Opting for a reset entails a fresh 70-hour clock after 34 hours, while forgoing a reset allows for running on recaps.

Running on recaps occurs when one drives beyond eight days without a 34-hour reset to restart the 70-hour clock. At midnight after an eight-day cycle, “recap hours” get added to the 70-hour clock, equivalent to the hours on duty and driving the same day the previous week. Hence, each night at midnight, the hours worked a week prior are gained.

Recap Hours in USA

In the USA, the 70-hour recap refers to having 70 hours available in your logbook following a 34-hour reset period. Initially, you must complete your driving hours within 8 days in the USA before you can utilize the recap hours.

Examples of 70-Hour 8-Day Recaps:

Let’s illustrate with examples for clarity.

Example 1: If on Monday, you worked 10 hours, the following Tuesday at midnight (eight days later), you gain an additional 10 hours on your 70-hour clock.

Example 2: Consider a full week starting fresh on Monday. Over the next eight days (Monday through Monday), if you worked 8 hours each day, except zero hours on Wednesday, you’d have 14 hours left on your 70-hour clock by the week’s end.

In utilizing recap hours, at midnight on Tuesday of the second week, you’d receive eight additional hours on your clock, based on the hours worked the previous Monday, totaling 24 hours. The cycle continues similarly for subsequent days.

Bear in mind, doing a reset initiates a fresh 70-hour clock for the week, rendering you unable to utilize recap hours until completing another eight-day period. Your Hours of Service recap will display daily usage and automatically factor in recap hours gained at midnight. Rely on your electronic logging device (ELD) for accurate tracking, and consider maintaining a written calendar for efficient trip planning and monitoring your driving hours.

Recap Hours in Canada

In Canada, the 70-hour recap denotes having 70 hours available in your logbook following a 36-hour reset period. Initially, you must complete your driving hours within 7 days in Canada before you can utilize the recap hours. For instance, if on April 4th, you completed a 36-hour reset and commenced with a full 70-hour clock, the remaining hours on April 11th indicate what is available. Currently, I have 59 minutes remaining on my 70-hour limit. With a delivery scheduled for 07:00 tomorrow and only a 20-minute distance, the immediate future appears manageable.

Forecasting for tomorrow, a reflection on the activities of the past 7 days is essential. Beginning from 7 days ago, at midnight tonight, the eighth day commences, with April 4th being 7 days prior. Consequently, tomorrow brings back 9 hours and 55 minutes. Adding this to the 59 minutes remaining on the 70-hour limit, I start tomorrow with a total of 10 hours and 54 minutes. This pattern continues, with each subsequent day adding the accrued hours to the remaining balance. I trust this explanation aids in comprehension, as practical experience often enhances understanding.
