HOS Dials in the Driver App

The four dials, or clocks, are located on the HOS Screen in the driver app. These dials represent how many hours or minutes remain in a driver's Break, Drive, Shift, and Cycle clocks. 

The top left Break clock shows the time remaining in a driver’s shift until their 30-minute break.

The top right Drive clock displays the drive time remaining in a driver’s shift until they are required to take a 10-hour break.

The bottom left Shift clock represents how many hours of "On Duty" time a driver has before they must take a 10-hour break. Commonly referred to as a "daily limit". 

The bottom right Cycle clock indicates the time remaining on a driver’s cycle. This typically represents a 7/8 day or weekly limit.

The color surrounding any of these dials will turn yellow when you are nearing violation and will appear red when you are in violation.

Nearing Violation: You will receive a warning when you are nearing violation and the dial will be surrounded in yellow.

In Violation: The dial will be highlighted in red.
