HOS Chart Screen

The HOS Chart screen lets you view a graphical display of your HOS status over time. You can display this screen by tapping the HOS Chart Screen button from the HOS Status or Event List screens.

This screen displays your daily log as a chart, with a timeline running left to right covering the 24-hour log period, and a row for each possible HOS status. The blue line moves between the different HOS status codes to indicate your status at any given point during the log period. On the far right of each row is the accumulated time spent in that status in the log period. The date of the log you are currently viewing displays above the chart. You can touch-scroll the chart left and right to view the full 24-hour period.

In the title bar, the Certify button lets you review and certify the HOS log represented by this chart. If the HOS log has already been certified, the label Certified is shown instead.

The green vertical line is a cursor that indicates the currently selected event or time. Just below the chart are two buttons, and , which let you move to the previous or next event in your log.

At the bottom of the screen are the following controls:

Change the date shown in the chart by selecting a new date from a list of possible days.

Edit the selected event, changing the status, the time, or any notes. Shown only if you have selected an event.

Add a new event at the time where the cursor is. Shown only if you have not selected an event.
