Fatigue & Hours-of-Service Awareness

What does the 14-hour rule mean for a property-carrying driver?

  • A.It is the total driving time allowed each week
  • B.It is the maximum window after coming on duty in which you may drive, even if you take breaks
  • C.It is the required off-duty time between shifts
  • D.It is the maximum time you may spend loading
Correct answer

B. It is the maximum window after coming on duty in which you may drive, even if you take breaks

Why

After you come on duty, you may not drive once the 14th consecutive hour has passed, and off-duty breaks do not extend that window. Only a qualifying sleeper or off-duty period under specific exceptions, or the required reset rules, changes the calculation.
