Which statement is true?

1. Ten consecutive hours off duty:
You may spend time in your sleeper berth to get some of, or all of, the 10 consecutive hours of off duty time. When getting your 10 consecutive hours of off duty time, what is most important is that you do not go on duty or drive during those 10 hours. At the end of the 10 consecutive hours of combined sleeper and/or off duty time, your 11-hour driving and 14 hour duty-period limits would completely restart.
2. Eight hours of sleeper berth time:
You may also use the sleeper berth to extend the 14 hour limit. Any period in the sleeper berth of at least 8 consecutive hours will not count as part of the 14 hours, and, therefore, would allow you to extend the time during which you could use your maximum 11 hours of driving.
3. Split sleeper / off duty time:
You may also use the sleeper berth in a different way to get the “equivalent of at least 10 consecutive hours off duty.” To do this, two rest periods are required. You must spend at least one of the two required rest periods in your sleeper berth. The required rest period in the sleeper berth must be at least 8 consecutive hours (but less than 10 consecutive hours). This rest period will not count as part of the 14 hours. The other, separate, rest period must be at least 2 consecutive hours (but less than 10 consecutive hours). This rest period may be spent in the sleeper berth, off duty, or sleeper berth and off duty combined. It will count as part of the 14 hours (unless you spend at least 8 consecutive hours in the sleeper berth). It does not matter which rest period you take first. After you complete your second re­quired rest period, you will have a new point on the clock from which to calculate your hours available. This new “calculation point” will be at the time you completed your first required rest period.
