Quote From The CDL Manual:
Violations: There is a 14 hour rule violation from 10:00 p.m. - 11:00 p.m.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available starting at midnight. The driver completed 9 hours of driving by 11:00 p.m. and went off duty, so there are no violations of the 11 hour rule.
Explanation - 30 Minute Break: Since the driver was never on duty longer than 8 consecutive hours, the 30 minute break provision was never a factor.
Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at midnight. The driver used 10 of those hours by 10:00 a.m. before entering the sleeper berth for 8 consecutive hours. The 8 consecutive hour sleeper berth period is excluded from the 14 hour limit, but the 1 hour off duty period connected to that sleeper berth period is not. So the 14 hour limit was reached at 10:00 p.m., 4 hours after the end of the sleeper berth period, and the driver violated the rule by continuing to drive for another hour. To remain in compliance, the driver should have either stopped driving at 10:00 p.m., or remained in the sleeper berth from 6:00 p.m. - 7:00 p.m.
What time does a 14 hour rule violation occur?
- At 3:00 p.m.
- At 6:00 p.m.
- There is no 14 hour rule violation in this example
- At 5:00 p.m.
Quote From The CDL Manual:
Violations: There is a 30 minute break violation from 11:00 a.m. to 1 p.m. and again from 5 p.m. to 6 p.m.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver was eligible to drive for up to 11 hours beginning at 4:00 a.m. The driver drove only 6 hours, within the legal limit.
Explanation - 30 Minute Break: The driver went on duty at 4:00 a.m. and was eligible to drive during the next 8 consecutive hours until noon. By that time, a 30 minute off duty break would be required. However, the driver never went off duty within that 8 hour period. Therefore, at noon, the driver was in violation of the 30 minute break provision. Since drivers may remain on duty without a 30 minute break, there is no violation during the on duty hours of 1 p.m. to 5 p.m. However, at 5 p.m. the driver returned to driving but still never took 30 minutes off duty. As such, this driver was in violation of the 30 minute break provision again from the hours of 5 p.m. to 6 p.m. To remain in compliance, the driver should have taken a 30 minute off duty break at 10:00 a.m. This would have kept the driver in compliance for both driving periods.
Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at 4:00 a.m. The driver stopped driving a CMV upon reaching the 14 hour limit at 6:00 p.m., so there are no violations.

Violations:There are no violations.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 2:00 a.m. on Day 1. The driver used those 11 hours by 3:00 p.m. when he or she entered the sleeper berth for 8 consecutive hours. Because the driver accumulated at least 10 hours of rest using a combination of at least 8 consecutive hours in a sleeper berth and another break of at least 2 consecutive hours, he or she was eligible for the split sleeper berth provision. This moves the calculation point to the end of the first of the two periods of rest, or 9:00 a.m. on Day 1. Starting the calculation from there, the driver accumulated another 11 hours of driving by 4:00 a.m. on Day 2. By 6:00 a.m. on Day 2, the driver accumulated another pair of qualifying breaks totaling at least 10 hours. This moves the calculation point again, to the end of the first of the two breaks, or 11:00 p.m. on Day 1. From there, the driver accumulated another 11 hours of driving by noon on Day 2. This pattern continued, with no 11 hour violations.
Explanation - 30 Minute Break: A 30 minute break is only required when a driver wants to drive a CMV after being on duty for longer than 8 hours without a 30 consecutive minute off duty break. On both days in this example, the driver was never on duty long enough to require a 30 minute break.
Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 2:00 a.m. on Day 1. The driver accumulates 13 hours by 3:00 p.m. before entering the sleeper berth. Because the driver then met the requirements for the split sleeper berth provision, the calculation point moves to the end of the first qualifying break, or 9:00 a.m. on Day 1. So at 11:00 p.m. on Day 1, the driver had accumulated 6 hours (any sleeper berth period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation). By 6:00 a.m. on Day 2, the driver accumulated another pair of qualifying breaks totaling at least 10 hours and has not exceeded the 14 hour duty limit. This moves the calculation point again, to the end of the first of the two breaks, or 11:00 p.m. on Day 1. From there, the driver accumulated 13 of 14 hours by noon on Day 2 (any sleeper berth period of less than 8 hours is included in the 14 hour calculation). This pattern continued, with no violations.

Quote From The CDL Manual:
Day 1
Day 2
Violations: There is a 30 minute break violation on Day 1 which occurred from 6:00 p.m. to 7:00 p.m. Then, on Day 2, there is another 30 minute break violation from 4:00 p.m. until 9:00 p.m. as well as an 11 hour rule violation from 4:00 p.m. - 9:00 p.m. and a 14 hour rule violation from 7:00 p.m. - 9:00 p.m.
Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. After driving 8 hours (3 + 2 + 3), the driver took 8 consecutive hours in the sleeper berth, which, combined with the earlier 2 consecutive hours in the sleeper from 5:00 p.m. to 7:00 p.m. on Day 1, made the driver eligible for the split sleeper berth provision. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 9:00 p.m. on Day 1. Between 9:00 p.m. on Day 1 and 8:00 a.m. on Day 2, the driver had 3 hours of driving, so at 8:00 a.m. there were 8 hours remaining (11 - 3), but he or she continued to drive for an additional 5 hours, after reaching the 11 hour limit at 4:00 p.m.
Explanation - 30 Minute Break: On Day 1, the driver remained on duty for more than 8 consecutive hours. While remaining on duty for longer than 8 consecutive hours is perfectly legal, the driver may not operate a CMV after being on duty for more than 8 consecutive hours unless a 30 minute break is taken. In the Day 1 example, the driver didn't meet that requirement until being on duty for 9 hours (1 hour beyond the limit), thereby violating the 30 minute break provision from 6:00 p.m. to 7:00 p.m. The driver also failed to take a 30 minute break on Day 2. Since the driver was on duty (driving) for more than 8 hours beginning at 4:00 p.m., all drive time after 4:00 p.m. was in violation of the 30 minute break provision.
Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 10:00 a.m. on Day 1. The driver reached the 14 hour limit at midnight (the 2 hour sleeper berth period is included in the 14 hour calculation because it is less than 8 hours). The driver then entered the sleeper berth for 8 consecutive hours and took advantage of the split sleeper berth provision. This moves the 14 hour calculation point to 9:00 p.m. on Day 1, the end of the first of the two qualifying breaks. Counting forward from there (and excluding the 8-hour sleeper period), the driver had 11 hours remaining as of 8:00 a.m. on Day 2. Those 11 hours were used up by 7:00 pm
