49 CFR § 395.3

What does 49 CFR § 395.3 require?

The federal hours-of-service rules for property-carrying CMV drivers are built around four limits: (1) the 11-hour driving rule, maximum 11 hours of driving after 10 consecutive hours off duty, (2) the 14-hour on-duty window, all driving must occur within 14 hours of the driver's first on-duty time after their 10-hour break, (3) the 30-minute break requirement, a 30-minute non-driving break is required before driving more than 8 cumulative hours, and (4) the 60/70-hour weekly limit, total on-duty time may not exceed 60 hours in 7 consecutive days or 70 hours in 8 consecutive days. A 34-hour off-duty period resets the weekly clock. These rules apply to every minute of CMV operation and are enforced through the ELD mandate (49 CFR 395.8).

Who must comply with 49 CFR § 395.3?

All drivers of property-carrying CMVs in interstate commerce. Property-carrying CMVs include trucks 10,001+ lbs GVWR, hazmat carriers requiring placards (any size), and combinations totaling 10,001+ lbs GVWR. Passenger-carrying drivers are governed by a separate but similar regulation (49 CFR 395.5: 10-hour driving rule and 15-hour duty window). Intrastate drivers must comply with state-specific HOS rules, which in most states mirror or directly adopt the federal limits. Short-haul drivers operating under 49 CFR 395.1(e)(1), within 150 air-miles and returning within 14 hours, are exempt from the 30-minute break but still subject to the 11/14/60-70 limits.

What happens if you violate 49 CFR § 395.3?

HOS violations result in civil monetary penalties set by 49 CFR 386 Appendix B: up to $1,584 per day, capped at $15,846, for recordkeeping violations, or up to $19,246 for non-recordkeeping violations. Common citations include exceeding the 11-hour driving limit, exceeding the 14-hour on-duty window, missing the 30-minute break, exceeding the 60/70-hour weekly limit, and false reporting of duty status. At roadside, a driver found exceeding HOS limits is placed out of service for the required rest period before being allowed to continue. HOS violations affect the CSA Compliance BASIC, which determines inspection-selection priority and safety-rating eligibility. Patterns of HOS violations can trigger a Compliance Review and Conditional or Unsatisfactory safety rating.

How to comply (implementation checklist)

1. 1Train every driver on the 11/14/30-minute/60-70 rules and the 34-hour restart option.
2. 2Configure your ELD to alert drivers as they approach the 11-hour, 14-hour, and 70-hour limits.
3. 3Establish dispatch policy that NEVER pressures a driver to exceed HOS limits.
4. 4Document HOS coaching for any driver flagged by ELD edits or near-misses.
5. 5Maintain the 8-day supporting-document trail (fuel, tolls, BOLs) to verify ELD accuracy.
6. 6Review the ELD compliance dashboard weekly for HOS violations across the fleet.
7. 7Track the 60/70-hour weekly clock proactively: alert dispatchers 5-10 hours before limit.
8. 8Plan loads with realistic HOS-compliant ETAs; do not commit to ETAs that require HOS violation.
9. 9For short-haul exempt drivers, audit timecards monthly for the 14-hour return-window compliance.
10. 10Document any HOS exception used (adverse driving conditions, short-haul, agricultural).

Common misinterpretations

• Misinterpretation: 'I have 14 hours to drive.' Reality: You have 11 hours of driving time within a 14-hour on-duty window. The remaining 3 hours of the 14-hour window are for non-driving on-duty time (loading, fueling, paperwork). You cannot drive after the 11-hour or 14-hour limit is reached, even if you've only driven 1 hour.
• Misinterpretation: 'Sleeper berth time counts as off-duty.' Reality: Sleeper berth time counts toward the required 10-hour break only if it meets specific requirements (continuous 8 hours minimum, or split sleeper berth using the 8/2 or 7/3 method per 49 CFR 395.1(g)). Sleeper berth time does NOT extend the 14-hour on-duty window: it pauses on-duty time but does not reset it.
• Misinterpretation: 'I can keep driving as long as my logs say off-duty.' Reality: This is logbook fraud. ELD time records are tracked in real time and cross-referenced with engine activity, GPS movement, and supporting documents (fuel, tolls, BOLs). Knowing falsification of records carries a civil penalty of up to $15,846 under 49 CFR 386 Appendix B (a)(2), plus potential criminal prosecution.
• Misinterpretation: 'The 34-hour restart is required every week.' Reality: The 34-hour restart is OPTIONAL, it's a tool drivers can use to reset their 60/70-hour weekly clock. Drivers can also let the rolling 7-day or 8-day clock 'fall off' as time passes (each completed day rolls out of the calculation). The 34-hour restart simply accelerates the reset.
• Misinterpretation: 'Short-haul drivers don't have any HOS limits.' Reality: Short-haul drivers under 49 CFR 395.1(e)(1) are exempt from the 30-minute break and the RODS requirement, but they are still subject to the 11-hour driving limit and the 60/70-hour weekly limit. They must maintain timecards and return to their work-reporting location within 14 hours.
