To allow drivers to pause the shift clock, you can enable a Waiting Time exemption. This duty status will be a dotted line for the driver in the Off Duty row. Samsara will not add this duty status as a 5th line.
For oilfield operation drivers, you will also need to configure a 24-hour reset period in the Compliance settings area of the dashboard.
The waiting time exemption is defined as follows per §395.1(d):
(d) Oilfield operations. (1) In the instance of drivers of commercial motor vehicles used exclusively in the transportation of oilfield equipment, including the stringing and picking up of pipe used in pipelines, and servicing of the field operations of the natural gas and oil industry, any period of 8 consecutive days may end with the beginning of any off-duty period of 24 or more successive hours.
(2) In the case of specially trained drivers of commercial motor vehicles that are specially constructed to service oil wells, on-duty time shall not include waiting time at a natural gas or oil well site. Such waiting time shall be recorded as “off duty” for purposes of §§395.8 and 395.15, with remarks or annotations to indicate the specific off-duty periods that are waiting time, or on a separate “waiting time” line on the record of duty status to show that off-duty time is also waiting time. Waiting time shall not be included in calculating the 14-hour period in §395.3(a)(2). Specially trained drivers of such commercial motor vehicles are not eligible to use the provisions of §395.1(e)(1).
To enable this exemption for drivers, see HOS and Exemption Settings.
