Hours of Service, Fatigue, and Driver Wellness

What this domain tests

Hours-of-service (HOS) questions for passenger carriers test the 10-hour driving limit, the 15-hour on-duty window, the 60/70-hour limits, and the 8-hour reset, plus fatigue and wellness judgment.

The core limits

  • 10-hour driving limit: after 10 hours of driving, you must have 8 consecutive hours off duty before driving again.
  • 15-hour on-duty window: you may not drive after the 15th hour of coming on duty, following 8 consecutive hours off. Breaks do not extend the window.
  • 60/70-hour limits: 60 hours on duty in 7 consecutive days, or 70 in 8, unless the carrier uses the 34-hour restart.
  • 34-hour restart: 34 consecutive hours off duty resets the 60/70 calculation.
  • Passenger carriers are not subject to the 30-minute break rule that applies to property-carrying drivers, but your carrier may impose one.
  • Record of duty status: keep accurate logs, retain the required records, and use an ELD if the carrier is required to.

Fatigue and wellness

  • Get 7–9 hours of sleep before a duty period; do not rely on caffeine to replace sleep.
  • Take scheduled rest breaks, eat light meals, and stay hydrated in Florida heat.
  • Do not drive while ill, on impairing medication, or after alcohol; the same standards that apply to any CMV driver apply to you.
  • Recognize microsleeps, lane drift, and missed signs as warning signs and stop safely.
  • Report fatigue to dispatch; a late trip is better than a crash.

Worked example

A driver reports at 06:00, drives 3 hours, spends 3 hours on duty not driving, takes a 1-hour lunch, drives 3 hours, and then waits 4 hours for a delayed passenger. At 21:00 the 15-hour window closes. The driver has only 6 driving hours but may not drive again until 8 consecutive hours off duty. The lunch and the wait do not extend the window.

Traps that cost marks

  • Thinking a lunch break extends the 15-hour window.
  • Applying the property-carrier 30-minute break rule to a passenger bus.
  • Counting only driving time and ignoring on-duty-not-driving time.
  • Treating the 34-hour restart as optional bookkeeping rather than an actual reset.
