What 395.3B2-HOSPD means in plain language
This violation is triggered when you drive a commercial vehicle after you've accumulated more than 70 hours of on-duty time in the previous 8 consecutive days. The regulation exists to prevent driver fatigue. Once you hit 70 hours on duty within any rolling 8-day window, you must stop driving until you've taken at least 34 consecutive hours off duty (or completed your required reset).
The key word is "on-duty"—that includes driving time, but also time spent inspecting your vehicle, loading/unloading, fueling, paperwork, and any other work-related tasks. Off-duty time, sleeper berth time, and personal conveyance don't count toward the 70-hour threshold.
If an inspector checks your logbook or electronic logging device and sees that you were driving while your 8-day on-duty total exceeded 70 hours, you'll be cited. This is a documentary violation—it's determined by your records, not by whether you felt tired or actually drove unsafely.
What our enforcement data actually shows
Across 13 million inspections in our database, 395.3B2-HOSPD ranks #788 of 3,036 FMCSR codes by citation volume. We recorded 762 all-time citations for this violation, with 456 citations in the last 12 months and 60 citations in the last 90 days.
The out-of-service rate for this code stands at 52.9%—meaning roughly half of drivers cited for this violation are pulled out of service immediately. This is substantially higher than the all-FMCSR average out-of-service rate of 31.4%, indicating that inspectors treat this violation with significant severity. Of the 762 all-time citations, 403 resulted in an out-of-service order, while 359 did not.
Monthly volume has fluctuated over the past year. October 2025 was the highest month with 63 citations (36 OOS), while February 2026 was the lowest with 21 citations (14 OOS). Recent months show sustained enforcement: March 2026 had 32 citations with 16 out-of-service orders.
Who gets cited most
Our inspection records show this violation is not uniformly distributed across the country. In the last 180 days, Missouri led with 38 citations (50.0% OOS rate), followed by Indiana with 20 citations (20.0% OOS rate) and Colorado with 14 citations (78.6% OOS rate).
OOS-rate variation is material here. Colorado and Arizona both enforce this code aggressively: Colorado at 78.6% OOS rate and Arizona at 84.6% OOS rate (13 citations). Oregon enforced an even stricter standard, with a 100% out-of-service rate on 10 citations in the 180-day window. By contrast, Indiana's 20.0% OOS rate suggests their inspectors may cite the violation but allow continued operation more frequently.
Our data shows carriers such as RP Florida Transport Inc (USDOT 3594307) with 8 citations and FAS Services LLC (USDOT 4282766) with 8 citations appearing frequently in violation records. OKM Trucking Inc (USDOT 3199678) and Mike's Way Trucking LLC (USDOT 3225140) also each recorded 8 citations across the database.
How severe is this compared to similar codes
Within the Hours of Service category, this violation sits in a middle-severity band. False record of duty status (395.8E-HOSPD) has been cited 83,660 times with a 9.6% OOS rate—far more common but less likely to result in immediate out-of-service. By contrast, failing to keep records of duty status using the prescribed method (395.8A1-HOSP) carries a 92.9% OOS rate across 52,266 citations, indicating that recordkeeping failures at the structural level are treated more harshly than exceeding the 70-hour threshold.
ELD-related violations are cited much more frequently. ELD Form and Manner (395.24) has 106,486 citations but a 0.0% OOS rate, reflecting that these are typically documentation or setup issues. The 52.9% OOS rate for 395.3B2-HOSPD suggests it ranks among the more operationally serious violations inspectors encounter.
How to avoid it
Track your on-duty hours meticulously. Use your electronic logging device or logbook to monitor your cumulative on-duty time. Set a personal alert at 65–66 hours within your 8-day cycle so you can plan your next 34-hour reset before hitting the 70-hour mark. This is not optional compliance—it's a mathematically deterministic violation.
Understand what counts as "on-duty." Beyond driving, on-duty time includes vehicle inspections, fueling stops, shipper/receiver delays where you remain responsible, scale house time, and administrative work. Many drivers undercount these tasks. If you spend 2 hours daily on non-driving on-duty work and 9 hours driving, you're accumulating 11 hours per day toward the 70-hour limit—not 9.
Plan your 34-hour reset strategically. When you approach 66 hours, don't try to squeeze in a final short haul. Take your required off-duty or sleeper berth time. Our data shows that false records of duty status (395.8E-HOSPD) co-occur with 70-hour violations 19 times in the last 90 days—often because drivers or companies falsify logs to avoid the reset. That compounds your violation exposure.
Coordinate with dispatch on weekly workload. If your dispatch consistently assigns loads that push you against the 70-hour boundary, you and your fleet need to discuss load distribution. Carriers cited multiple times—such as those with 8 citations—likely lack adequate load planning. Work with your safety manager to build schedules that respect the limit with a cushion.
Document your off-duty time clearly. The most common co-occurring violation is false record of duty status (395.8E-HOSPD), with 19 shared inspections in the last 90 days. Inspectors are checking whether your claimed off-duty periods actually exist. Don't log time as off-duty if you're actually working—it will be caught, and you'll face two violations instead of one.
Perform pre-trip vehicle inspections efficiently. Our data shows Freightliner (213 citations), Volvo (80 citations), and Ford (72 citations) vehicles are among those most frequently cited. Regardless of your equipment type, conduct your pre-trip inspection before your on-duty time begins when legally possible, or complete it quickly to minimize on-duty accumulation.
