Personal Conveyance - FMCSA Guidance

Clarification of Impact to On-Duty Hours
Personal conveyance is an off-duty status. Therefore, there are no impacts to the 11- or 14-hour limitations for truck drivers, the 10- or 15-hour limitations for bus drivers, the 60/70-hour limitations, the 34-hour restart provisions, or any other on-duty status.
Leaving a Shipper or Receiver to go to a Safe Place for Required Rest
The movement from a shipper or receiver to the nearest safe resting area may be identified as personal conveyance, regardless of whether the driver exhausted his or her HOS, as long as the CMV is being moved solely to enable the driver to obtain the required rest at a safe location. The Agency recognizes that the driver may not be aware of the direction of the next dispatch and that in some instances the nearest safe resting location may be in the direction of that dispatch. If the driver proceeds to the nearest reasonable and safe location and takes the required rest, this would qualify as personal conveyance. FMCSA recommends that the driver annotate on the log if he/she cannot park at the nearest location and must proceed to another location.
Enhancing Operational Readiness
Enhancing operational readiness includes on-duty movement of a CMV that provides a commercial benefit to the motor carrier. For example, if the movement places the load closer to the destination, it may not be considered personal conveyance, except under some circumstances. Additionally, if a driver who is under dispatch stops at a location such as his/her home, because the driver's home is closer to the next destination or pick up location, then this would not be personal conveyance.
Returning to the Last On-Duty Location
The driver is not required to return to the previous on-duty location. A driver may resume on-duty status immediately after an off-duty status regardless of the location of the CMV.
