Day 2

There is an 11 hour rule violation from 12:30 p.m. - 1:00 p.m., and a 14 hour rule violation from noon - 1:00 p.m., both on Day 2.
- 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. After 7 1/2 hours of driving (3 + 2 1/2 + 2), the driver entered the sleeper berth for 2 consecutive hours, making him or her eligible for the split sleeper berth provision. The driver accumulated at least 10 hours of rest using a combination of at least 8 (but less than 10) consecutive hours in a sleeper berth and another break of at least 2 (but less than 10) consecutive hours. This moves the calculation point to the end of the first of the two qualifying periods of rest, or 10:00 p.m. on Day 1. The next 11 hour calculation starts there, and the driver reached the 11 hour driving limit at 12:30 p.m. on Day 2 but still continued to drive for another 1/2 hour.
- 30 Minute Break: On both Day 1 and Day 2, the driver never spent more than 8 consecutive hours on duty or driving and therefore, no violation occurred on either day.
- 14 Hour Limit: Calculation of the 14 hour limit begins at 10:00 a.m. on Day 1. At midnight on Day 1, the driver still had 9 hours remaining because any sleeper berth period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation. By 4:00 a.m. on Day 2, the driver had 5 hours remaining (14 - 3 - 2 1/2 - 1 1/2 - 2 = 5). The driver then took a break of at least 2 consecutive hours, making him or her eligible for the split sleeper berth provision. This moves the calculation point to the end of the first of the two qualifying periods of rest, or 10:00 p.m. on Day 1. The next 14 hour calculation starts there, and the driver reached the end of the 14 hour duty period at noon on Day 2 and drove for 1 hour over the 14 hour limit.
