14 Hours Rule

A driver may not drive beyond the 14th hour after coming on-duty following 10 hours off-duty.


This means, once the driver begins an on-duty period of any kind, the 14 hr.  The clock starts. (Line 3 "Driving", or Line 4 "On-Duty Not Driving").


If a driver starts an on-duty status at 06:00 AM, The driver will have to stop driving at 08:00 PM.  (14 hours later)

Lunch breaks, fueling, or other off-duty time do not extend the 14-hour period. The 14 hours are consecutive from the time you start your tour of duty.

On-duty time is defined as all time from the time you begin work or are required to be ready for work until you are relieved from work and all responsibility for doing work.

On-duty time includes time spent:

- Waiting to be dispatched

- Inspecting, servicing, or conditioning a commercial motor vehicle;

- Driving (at the controls of your vehicle);

- In or on your vehicle (except time spent in the sleeper berth), yes time spent in the passenger seat;

- Loading or unloading your vehicle;

- Repairing, obtaining assistance, or attending to a disabled vehicle;

- Performing any other work for a motor carrier;

- Complying with drug or alcohol testing requirements; and

- Performing compensated work for any other employer.

- Time spent being inspected by DOT/CVSA Inspectors.

Easy way to remember this is:

- If you're in front of the curtain log ON-DUTY NOT DRIVING.

- If you're behind the curtain log SLEEPER or OFF-DUTY.


How do I calculate the 14 Hour rule?

uBy “excluding” any sleeper berth period of at least 2 hours or more which, which when added to a subsequent sleeper berth period  totals at least 10 hours., and
uBy including all on-duty time, all off-duty time, all sleeper berth periods of less than 2 hrs and all other sleeper berth periods not used in the calculation, other than the 2 hours or more split sleeper excluded above, used in the 10 hour total.

ØNote: Does not have to be the next one.


Can a driver work past his/her  14th hour?

uYes!   uUnloading, loading, fueling, repairs, etc. are still allowed after the 14th hour.  (Logged on Line 4), However, this time still applies to the maximum for the 60/70 hrs on-duty over 7/8 consecutive days. (Line 4), The Driver must have a full consecutive 10-hr. break before resuming driving.
