Options for resetting the 14-hour clock
['Hours of Service']

- The 14-hour clock is reset if the driver gets 10 consecutive hours off.
- Using the split-sleeper option to get two “qualifying” breaks that add up to 10 hours is the only way for most drivers to “extend” the 14-hour day without having to take 10 consecutive hours off.
Each of the options available for obtaining 10 hours of required rest will serve to reset the 14-hour clock. For example, the 14-hour clock would be reset if the driver had:
- Option 1: 10 consecutive hours off duty
- Option 2: 10 consecutive hours in a sleeper berth
- Option 3: 10 consecutive hours combining sleeper-berth and off-duty times
- Option 4: Used the split-sleeper option to get two “qualifying” breaks that add up to 10 hours (this is the only way for most drivers to “extend” the 14-hour day without having to take 10 consecutive hours off).
Under Option 4, after obtaining the two qualifying breaks, available time under the 14-hour limit is calculated starting at the end of the first break. Neither qualifying break is counted as part of the 14 hours.
Option 3 includes the ability to log off duty for up to three hours while riding in the passenger seat of a moving vehicle before or after spending at least seven hours in a sleeper berth.
