60-hour limit

What is the 60-Hour/7-Day Limit?

The 60-hour/7-day rule is a primary Hours-of-Service (HOS) constraint established by the Federal Motor Carrier Safety Administration (FMCSA). Like the 70-hour/8-day rule, it serves as a “weekly” limit on on-duty time, designed to prevent the dangerous accumulation of driver fatigue.

Core Regulation

• The Limit: A driver may not exceed 60 hours of on-duty time within any period of 7 consecutive days.

• Scope: This regulation applies specifically to motor carriers that do not operate every day of the week. Drivers for carriers that do operate every day are typically subject to the 70-hour/8-day rule instead.

• The Rolling Window: This is a continuous calculation. As each new day is added to the driver’s schedule, the hours from the 7th day back are removed from the calculation. This constant “rolling” ensures that the driver never exceeds 60 hours of duty within any 168-hour (7-day) timeframe.

What Constitutes “On-Duty” Time?

The 60-hour limit is an aggregate of all work-related activities, not just driving time. It includes:

• Driving time.

• Loading and unloading cargo.

• Performing mandatory vehicle inspections (pre-trip/post-trip).

• Performing routine vehicle maintenance.

• Administrative tasks and paperwork.

Compliance and Technology

Compliance is enforced through the mandatory use of Electronic Logging Devices (ELDs). These devices automatically record a driver’s Record of Duty Status (RODS), providing an immutable audit trail for law enforcement.

• Consequences: Because these limits are federal law, non-compliance is taken very seriously. Penalties for exceeding these hours range from heavy monetary fines to the suspension of a Commercial Driver’s License (CDL), and in severe cases involving repeat or egregious violations, potential criminal charges.

The “Reset” Mechanism

To clear their accumulated hours and start a new 7-day cycle, a driver must take a 34-hour restart. This requires the driver to be off-duty for at least 34 consecutive hours. Once this rest period is successfully completed, the “clock” for the 60-hour cycle resets to zero.

To ensure your understanding of the 60-hour/7-day rule is fully aligned with FMCSA regulations, it is important to clarify how the “limit” and the “restart” function.

The 60-Hour Limit

The 60-hour rule is a cumulative limit on your on-duty time, not a countdown to a mandatory break.

• The Constraint: You cannot be on-duty for more than 60 hours in any period of 7 consecutive days.

• The “Rolling” Nature: You do not have to wait until you hit exactly 60 hours to take a break. You must monitor your hours daily so that, at any point in time, your total on-duty hours for the previous 7 days do not exceed 60. If you reach 60 hours, you must stop driving until enough “old” hours drop off the back end of your 7-day cycle to give you more available hours, or until you complete a 34-hour restart.

The 34-Hour Restart (The “Reset”)

There is a slight distinction in your notes regarding the 34-hour period:

• Not Mandatory Before 60: You are not strictly required to take a 34-hour break before reaching 60 hours. Many drivers continue working by managing their rolling hours (adding new days and dropping old days).

• The Purpose: The 34-hour restart is an optional tool used to clear your accumulated hours to zero. If you find yourself approaching the 60-hour limit and want to “reset” your clock, you take 34 consecutive hours off-duty. This resets your 60-hour cycle, allowing you to start fresh.
