HOS 16-Hour Short-Haul Exception (§ 395.1(o))
Property-carrying drivers can extend the 14-hour duty window to 16 hours once per 7 consecutive days under § 395.1(o), but the rule is narrow.
Eligibility
All four conditions must be met:
- Driver returns to and is released from the same normal work-reporting location at the end of the duty period (the location the driver started from in the past 5 duty periods)
- The driver was off duty for at least 10 consecutive hours before the duty period began
- Driver has not used the 16-hour exception in the prior 6 consecutive days (so once per 7 days max)
- Maximum 11 hours of driving still applies — the exception extends the 14-hour window only, NOT the 11-hour drive limit
Common mistakes
- "I returned to my home terminal" ≠ "same work-reporting location." If a driver alternates terminals across 5 days, the exception doesn't apply.
- Pre-trip + post-trip on the 16-hour day still count toward on-duty time. Total on-duty time cannot exceed 16 hours.
- The exception does NOT pause the 70-hour cycle. Use of the exception still counts against the 60/70-hour limit.
Documentation
Driver must note "16-hour exception" on the RODS (Records of Duty Status). ELD systems mark this automatically when configured; paper RODS require manual annotation.
When NOT to use this exception
- Passenger-carrying drivers — § 395.1(o) does not apply
- Hazmat placarded loads — depends on state restrictions
- When the driver may need it again within the same 7-day window — save it for the day you'll actually need it

How Compass surfaces this
Compass HOS module flags when a driver is approaching the 14-hour limit and whether they're eligible for the 16-hour exception (based on their 6-prior-day usage history). The decision stays with the carrier — Compass shows the eligibility, the driver/dispatcher choose.
