The 60/70-hour rule limits how much on-duty time a property-carrying commercial driver can accumulate during a defined period.
Under the federal Hours of Service (HOS) regulations, a carrier operating every day of the week generally follows the 70-hour limit, while a carrier that does not operate every day of the week may generally use the 60-hour limit.
Unlike the 11-hour driving limit and 14-hour rule, the 60/70-hour rule looks at the driver’s cumulative on-duty time across multiple days.
This makes it a rolling limit rather than a simple daily clock.
The 60/70-hour rule generally limits a property-carrying driver’s on-duty time to 60 hours in 7 consecutive days or 70 hours in 8 consecutive days, depending on the carrier’s operating schedule. Drivers can regain available hours through the applicable 24-hour recap or by taking a qualifying 34-hour restart.
What Is the 60/70-Hour Rule?
The 60/70-hour rule is the federal weekly HOS limit for property-carrying drivers.
It restricts the total amount of on-duty time a driver may accumulate over a rolling period.
Under 49 CFR §395.3(b):
- A driver may not drive after accumulating 60 hours on duty during any 7 consecutive days if the carrier does not operate every day of the week.
- A driver may not drive after accumulating 70 hours on duty during any 8 consecutive days if the carrier operates every day of the week.
The rule is therefore commonly called the weekly HOS limit, even though the calculation does not necessarily correspond to a Monday-through-Sunday workweek.
Why This Rule Matters
A driver might comply with every daily HOS requirement and still reach the weekly limit.
For example, a driver could remain within the daily driving and on-duty limits but accumulate enough on-duty time across several days to reach 70 hours.
Once the applicable limit is reached, the driver cannot continue driving until sufficient hours become available again.
What Is the Difference Between the 60-Hour and 70-Hour Rules?
The primary difference is how frequently the motor carrier operates.
| Rule | Applicable Operation | Maximum On-Duty Time |
|---|---|---|
| 60-hour rule | Carrier does not operate every day of the week | 60 hours in 7 consecutive days |
| 70-hour rule | Carrier operates every day of the week | 70 hours in 8 consecutive days |
The rule applies to the carrier’s operation, not simply the driver’s personal work preference.
A carrier should establish which cycle applies to its operation and ensure drivers understand the applicable limit.
How the Rolling HOS Cycle Works
One of the most important concepts is that the 60/70-hour limit is rolling.
It is not necessarily a fixed weekly reset.
For a carrier using the 70-hour cycle, the calculation considers the driver’s on-duty time over the applicable 8 consecutive days.
As an earlier day falls outside the calculation period, the on-duty hours from that day can drop off.
This can create additional available hours without the driver taking a full restart.
Simple Example
Suppose a driver has accumulated:
| Day | On-Duty Hours |
|---|---|
| Day 1 | 9 |
| Day 2 | 10 |
| Day 3 | 8 |
| Day 4 | 11 |
| Day 5 | 10 |
| Day 6 | 9 |
| Day 7 | 7 |
| Day 8 | 6 |
| Total | 70 |
The driver has reached the 70-hour limit.
The driver cannot continue driving under that cycle until hours become available through the applicable recap or restart provisions.
What Counts Toward the 60/70-Hour Limit?
The weekly limit is based on on-duty time.
This can include activities such as:
- Driving
- Loading or unloading when recorded as on duty
- Vehicle inspections
- Fueling
- Maintenance-related work
- Other compensated or work-related on-duty activities
This is different from calculating only driving time.
A driver can accumulate on-duty hours without continuously operating the vehicle.
What Is an HOS Recap?
An HOS recap allows a driver to determine how many hours will become available as previous on-duty hours fall outside the applicable rolling cycle.
For example, if a driver is using the 70-hour/8-day cycle, the driver’s available hours depend on the on-duty hours accumulated during the current and previous applicable days.
When an earlier day’s hours drop out of the calculation, those hours become available again.
Recap Example
Assume a driver has reached 68 hours on the 70-hour cycle.
If the oldest day contributing to the calculation contained 9 on-duty hours and that day rolls outside the applicable period, those hours may become available.
The driver could then have additional hours available for the current cycle, subject to all other HOS restrictions.
A recap therefore works differently from a restart.
What Is the 34-Hour Restart?
The federal HOS rules allow a driver to restart the 60/70-hour calculation after a qualifying period of at least 34 consecutive hours off duty.
This is commonly called the 34-hour restart.
The restart provides a way for a driver to begin a new weekly calculation instead of waiting for individual days to roll off the previous cycle.
However, drivers should not confuse the restart with the daily 14-hour window.
A restart affects the 60/70-hour cumulative limit. It does not simply add hours back to an active 14-hour window.
60/70-Hour Rule vs. 11-Hour and 14-Hour Rules
These HOS limits work together but measure different things.
| HOS Rule | What It Limits |
|---|---|
| 11-hour rule | Driving time during the workday |
| 14-hour rule | Length of the driver’s on-duty window |
| 60/70-hour rule | Cumulative on-duty time across the applicable cycle |
| 30-minute break rule | Extended driving without a qualifying interruption |
For example, taking a qualifying 30-minute break does not give a driver additional weekly hours.
Likewise, having weekly hours available does not allow a driver to exceed the daily 11-hour driving limit.
Real-World Example: Driver Approaching 70 Hours
Consider a long-haul driver operating for a carrier that uses the 70-hour/8-day cycle.
The driver has accumulated:
- Day 1: 10 hours
- Day 2: 9 hours
- Day 3: 11 hours
- Day 4: 8 hours
- Day 5: 10 hours
- Day 6: 9 hours
- Day 7: 7 hours
Total = 64 hours
The driver has 6 hours remaining under the 70-hour limit before considering any hours that may roll off or other applicable HOS provisions.
The driver must also remain within the daily driving and on-duty restrictions.
Another Example: Using a Recap
Imagine a driver reaches 69 hours on the 70-hour cycle.
The driver cannot simply drive another 5 hours because the weekly limit would be exceeded.
However, if hours from an earlier day fall outside the applicable 8-day calculation, those hours may become available.
The driver’s ELD can help identify the available hours, but drivers and fleet managers should understand the calculation rather than relying blindly on a displayed number.
Common Misconceptions About the 60/70-Hour Rule
Misconception 1: The Weekly Clock Resets Every Monday
Not necessarily.
The rule uses consecutive-day calculations, not necessarily a fixed calendar week.
Misconception 2: The 70-Hour Limit Means 70 Hours of Driving
It does not.
The 70-hour limit concerns on-duty time, while the daily 11-hour rule addresses driving time.
Misconception 3: A 34-Hour Restart Is Required Every Week
No.
A qualifying restart is an available method for restarting the cumulative cycle. Drivers may also regain hours through the applicable rolling recap.
Misconception 4: Available Weekly Hours Override the 14-Hour Rule
They do not.
Having 10 hours available under the weekly cycle does not mean a driver can continue operating after the driver’s applicable 14-hour window has expired.
Misconception 5: The ELD Automatically Makes the Carrier Compliant
An ELD helps record and calculate HOS information, but carriers and drivers remain responsible for accurate records and compliance decisions.
Common 60/70-Hour HOS Violations
Carriers should watch for these issues:
Exceeding the Weekly Limit
The driver continues operating after reaching the applicable 60- or 70-hour threshold.
Miscalculating Recap Hours
The driver incorrectly assumes hours have become available before they actually roll outside the cycle.
Confusing On-Duty With Driving Hours
A driver monitors only driving time and overlooks other on-duty activities contributing to the cumulative limit.
Ignoring the Applicable Carrier Cycle
The carrier fails to determine whether the 60-hour or 70-hour cycle applies.
Treating the Restart as a Daily Reset
The driver misunderstands what the 34-hour restart actually resets.
Best Practices for Managing 60/70-Hour Compliance
For Drivers
- Review your available weekly hours before accepting additional work.
- Monitor on-duty time, not just driving time.
- Understand your carrier’s applicable cycle.
- Review your ELD recap regularly.
- Plan future trips around available hours.
- Do not assume a new calendar week automatically resets your cycle.
For Fleet Managers
- Monitor drivers approaching the weekly threshold.
- Review recurring HOS patterns.
- Train drivers on recap calculations.
- Verify the correct 60- or 70-hour cycle is being used.
- Review ELD records for potential violations.
- Include weekly HOS compliance in regular safety reviews.
60/70-Hour Compliance Checklist
Before dispatching a driver, consider:
- Which cycle applies: 60/7 or 70/8?
- How many on-duty hours has the driver accumulated?
- How many hours remain available?
- Are any hours scheduled to roll off the cycle?
- Is the driver planning to use a recap?
- Is a 34-hour restart being used?
- Does the planned trip also comply with the 11-hour limit?
- Does the trip fit within the driver’s 14-hour window?
- Are ELD records accurate and current?
Expert Tips
The biggest mistake carriers make with weekly HOS limits is treating them as a standalone number.
A driver’s available 60/70-hour capacity should be evaluated alongside the 11-hour driving limit, 14-hour window, break requirement, and other applicable HOS provisions.

HOS Decision Framework
Use this simple sequence when determining whether a driver can continue operating:
Continue operating, while monitoring all applicable HOS limits.
If the answer to any step is No, the driver may need to stop operating or regain available hours before continuing.
Conclusion
The 60/70-hour rule controls cumulative on-duty time across a rolling period and is one of the most important parts of federal HOS compliance.
Carriers using the 60-hour/7-day cycle generally operate under a different cumulative limit than carriers using the 70-hour/8-day cycle.
Understanding the rolling calculation, HOS recap, and 34-hour restart can help drivers and fleet managers plan trips more effectively and avoid weekly HOS violations.
Most importantly, weekly hours should never be viewed separately from the driver’s other HOS requirements.
A strong compliance program combines accurate ELD records, driver training, proactive trip planning, and regular review of HOS data.

Frequently Asked Questions
The 60/70-hour rule limits the amount of on-duty time a property-carrying driver can accumulate during a rolling period. The applicable limit is generally 60 hours in 7 consecutive days or 70 hours in 8 consecutive days.
The 60-hour rule generally applies when a carrier does not operate every day of the week. The 70-hour rule generally applies to carriers operating every day of the week.
No. The 70-hour limit applies to cumulative on-duty time. The separate 11-hour rule limits driving time.
An HOS recap is the process of regaining available hours as older on-duty hours fall outside the applicable rolling 7- or 8-day calculation.
The 34-hour restart allows a driver to restart the applicable 60/70-hour calculation after taking at least 34 consecutive hours off duty, subject to the applicable federal HOS rules.
No. The restart addresses the cumulative 60/70-hour calculation. It does not simply reset an active 14-hour window.
No. A driver must comply with both the daily driving limits and the cumulative weekly on-duty limit.
Carriers should monitor cumulative on-duty time, train drivers on recap calculations, review ELD records, plan trips around available hours, and ensure drivers understand which weekly cycle applies.
