Understanding HOS clocks in the mobile app

How the Drive, Break, Shift, and Cycle clocks work

Overview

Drivers using ELD on the Maven App have access to four automatically tracked clocks. These clocks help drivers understand how much time they have left to drive, work, and remain compliant with Hours of Service (HOS) regulations.

The Maven app displays these four clocks on the HOS screen:

  • Drive Clock

  • Break Clock

  • Shift Clock

  • Cycle Clock

Drive Clock

  • Each driver may drive up to 11 hours before they must take a 10-hour off-duty break.

  • The Drive Clock counts all drive time while the vehicle is in motion.

  • The ELD automatically switches to Driving (D) status when the vehicle moves more than 5 mph.

  • When the driver reaches 11 hours of drive time in a shift, they cannot drive again until they take a continuous 10-hour off-duty (or sleeper berth) break, which resets the Drive Clock.

Break Clock

  • The Break Clock tracks when a driver must take a 30-minute off-duty (or qualifying break) period.

  • A driver is not allowed to drive more than 8 hours without taking a continuous 30-minute break.

  • The Break Clock counts down toward zero as the driver is on duty and driving.

  • The driver must take a 30-minute break at or before 0:00 on the Break Clock to remain compliant.

Shift Clock

  • The Shift Clock tracks the total length of the driver’s on-duty shift.

  • It is calculated by adding up:

    • Driving time

    • On Duty, Not Driving

    • Off Duty less than 2 hours

    • Sleeper Berth less than 2 hours

  • All of the above count toward the shift limit.

  • When the Shift Clock reaches 0:00, the driver must take a continuous 10-hour break off duty (or sleeper berth) before they can start a new shift and regain hours.

Cycle Clock

  • The Cycle Clock tracks the total number of on-duty hours worked over the last 8 days (or 80 hours in Texas, depending on fleet/region rules).

  • It is calculated using Shift time and Drive time only across that rolling 8-day period.

  • Once the driver approaches the cycle limit, their available hours will decrease accordingly.

  • The Cycle Clock resets only after the driver takes a continuous 34-hour off-duty/sleeper berth break.

    • A 10-hour break does not reset the Cycle Clock.

    • The full 34 hours must be continuous for the cycle to reset.
