60/70-hour on-duty limits.

Which limit your carrier is under, what the text says, and the hours left in the period.

No driving after 60 hours on duty in 7 consecutive days if the carrier does not operate every day of the week, or after 70 hours on duty in 8 consecutive days if it does (49 CFR 395.3(b)). Which limit applies depends on the employing motor carrier's operating days, not the driver's choice.

What the rule says

Paragraph (b) of 49 CFR 395.3 reads, as the eCFR showed it on November 2, 2026:

(b) No motor carrier shall permit or require a driver of a property-carrying commercial motor vehicle to drive, nor shall any driver drive a property-carrying commercial motor vehicle, regardless of the number of motor carriers using the driver's services, for any period after— (1) Having been on duty 60 hours in any period of 7 consecutive days if the employing motor carrier does not operate commercial motor vehicles every day of the week; or (2) Having been on duty 70 hours in any period of 8 consecutive days if the employing motor carrier operates commercial motor vehicles every day of the week.

The limit counts on-duty time, not only driving time.

On-duty time

Section 395.2 defines on-duty time as all time from the time a driver begins to work or is required to be in readiness to work until the time the driver is relieved from work and all responsibility for performing work. It includes all time at a plant, terminal, facility or other property of a motor carrier or shipper, or on any public property, waiting to be dispatched, unless the driver has been relieved from duty by the motor carrier; all time inspecting, servicing or conditioning any commercial motor vehicle; and all driving time. Because the weekly limit counts on-duty time, a driver can reach 70 hours with far fewer than 70 hours of driving.

Which limit applies

The split turns on whether the employing motor carrier operates commercial motor vehicles every day of the week. If it does, the limit is 70 hours in any period of 8 consecutive days. If not, it is 60 hours in 7. The test is applied to the carrier, so two drivers sitting side by side can be under different limits only if they work for different carriers. The words regardless of the number of motor carriers using the driver's services mean hours worked for other carriers count too.

How the count ends

Paragraph (c) says any period of 7 or 8 consecutive days may end with the beginning of an off-duty period of 34 or more consecutive hours. A driver who takes that restart starts a new count. Without one, the count rolls: as an old day falls out of the 7 or 8 day period, its hours stop counting. The calculator above is a simple rolling sum of the latest days you enter and does not model a restart.

Worked example

A carrier operates every day of the week, so the limit is 70 hours in 8 days. A driver's last 8 days are 9, 11, 10, 10, 8, 12, 9 and 8 hours, which total 77. That is 7 hours over the 70-hour limit. The values above, entered as shown, produce 77 and report that the driver is 7 hours over. A driver in that position would need a restart under 395.3(c) or for the oldest days to roll out of the period.

Limits of this page

This page repeats what the rule says and does no more. Whether a particular trip, load or day complies is a question for the motor carrier, its compliance staff or counsel. Day boundaries here are simplified to a list of daily totals. In the regulations, a consecutive-day period begins at the time designated by the motor carrier for a 24-hour period (395.2). The calculator takes your numbers as given.

Frequently asked questions

What are the 60 and 70 hour rules?

No driving after 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days, depending on the carrier (49 CFR 395.3(b)).

Which one applies to me?

The 70-hour/8-day limit applies if the employing carrier operates commercial motor vehicles every day of the week; otherwise the 60-hour/7-day limit applies.

Does the limit count only driving time?

No. It counts time on duty, which includes driving, inspecting, servicing, and waiting to be dispatched on carrier or shipper property unless relieved from duty (395.2).

How do I reset the count?

A 7 or 8 day period may end with the beginning of an off-duty period of 34 or more consecutive hours (395.3(c)).

Do hours worked for another carrier count?

Yes. Paragraph (b) applies regardless of the number of motor carriers using the driver's services.

Does the 70-hour limit apply to bus drivers?

Passenger-carrying drivers have the same 60-hour and 70-hour limits in 395.5(b).

Can adverse driving conditions extend these limits?

The text of 395.1(b)(1) refers to the maximums in 395.3(a) and 395.5(a), not to paragraph (b).
