Washington, D.C. — The Federal Motor Carrier Safety Administration issued its August 2025 Hours of Service revision on August 1, 2025, locking in a 14‑hour on‑duty window and a mandatory 34‑hour reset for all interstate freight movers.
The change hits every CDL‑A driver who hauls loads across state lines, operates a vehicle over 10,001 pounds, or transports hazardous materials. Compliance has always been a moving target; missing a tweak can trigger hefty fines, delayed deliveries, and lost pay. By codifying the 14‑hour workday and the 34‑hour off‑duty reset, the agency aims to curb fatigue‑related crashes while giving carriers a clear, uniform standard.
Under the new rule, drivers must begin each shift with at least ten consecutive off‑duty hours. The subsequent 14‑hour block counts all on‑duty activities—driving, loading, paperwork, waiting for dispatch—without pausing for coffee or bathroom breaks. Within that window, a maximum of 11 hours may be spent behind the wheel. Weekly limits remain at 70 hours over an eight‑day cycle or 60 hours over seven days, after which a 34‑hour off‑duty period restarts the clock. After eight cumulative clock hours of driving, a driver must take a minimum 30‑minute break, regardless of whether the pause occurs at a fuel stop, a loading dock, or a rest area. The regulation also permits a split‑sleeper arrangement: one rest segment of at least seven hours in the sleeper berth and a second segment of at least two hours either in or out of the berth, provided the total equals the required ten hours and does not infringe on the 14‑hour window. Exceptions apply for short‑haul runs under 150 miles, adverse weather, or emergency orders, allowing up to two additional hours for both drive time and the on‑duty window when conditions are truly uncontrollable.
What This Means for Drivers
OTR truck driver crews must reprogram electronic logging devices to flag the 30‑minute break after eight clock hours of travel. Owner‑operators juggling multiple loads will need to schedule the 34‑hour reset carefully to avoid breaching the 60/70‑hour weekly caps. Fleet managers should audit route plans to ensure no driver exceeds the 11‑hour driving limit within the 14‑hour on‑duty period. Drivers who regularly operate within 150 miles of home can continue using simplified record‑keeping, but they must still honor the break rule. Failure to log split‑sleeper periods correctly will automatically reduce the available on‑duty time, potentially forcing an extra off‑duty day.
Industry Reaction
Major carriers such as J.B. Hunt and Schneider have praised the clarity of the 34‑hour reset, noting that it simplifies scheduling across the nation. The Owner‑Operator Independent Drivers Association warned that the split‑sleeper provision could invite audit disputes if logs are not meticulously maintained. Safety advocates argue the 30‑minute break after eight hours will lower fatigue incidents, while some regional shippers fear the added downtime could increase freight costs. Across the board, trucking companies hiring now are updating compliance training to reflect the new FMCSA regulations.
