Logbook Example #17

Violations: There is a 14 hour rule violation from 5:00 p.m. – 10:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 2:00 a.m. The driver completed 11 total hours of driving by 10:00 p.m. and went off duty, so there were no violations of the 11 hour rule.

Explanation - 30 Minute Break: Once the driver began driving at 2:00 a.m., a 30-minute break was not needed until 10:00 a.m. (8 hours after first going on duty). Since the driver went off duty at 8:00 a.m. and spent more than 30 minutes off duty (sleeper berth), the driver was never in violation. During the hours of 5:00 p.m. to 10:00 p.m., the driver was only on duty (driving) for 5 hours before moving back to off duty. Even though the 14 hour limit was being violated during that time, the 30-minute break provision was not violated.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at 2:00 a.m. The driver reached the 14 hour limit at 4:00 p.m. and violated the rules by driving an additional 5 hours without first obtaining either: 10 consecutive hours off duty; or 8 consecutive hours in a sleeper berth. To remain in compliance the driver should have either:

• Obtained one additional hour off duty or in the sleeper berth in the middle of the day (for a total of 10 consecutive hours off duty) or;
• Remained in the sleeper berth for 8 consecutive hours, rather than only 7. Had the driver remained in the sleeper for 8 consecutive hours, that 8-hour sleeper period would have been excluded from the 14 hour calculation and the driver would have remained in compliance.

Logging Example #18

Day 1

Day 2

Violations: There are a total of 3 violations on Day 2. First, there is a 14 hour rule violation from 1:00 a.m. – 2:00 a.m. Second, there is a 30-minute break violation from 8:00 p.m - midnight. And third, there is also an 11 hour rule violation from 11:00 p.m. – midnight.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty using a combination of off duty and sleeper berth time, the driver was eligible to drive for up to 11 hours starting at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had driven 9 hours. By obtaining 10 consecutive hours off duty on Day 2, the 11 hour calculation point moved to noon on Day 2, at which point the driver had 11 hours of driving time available again. The driver violated the 11 hour rule by driving beyond the 11 hour limit between 11:00 p.m. and Midnight.

Explanation - 30 Minute Break: On Day 1, the driver was never required to take a 30 minute break because the longest stretch of on duty time during the entire day was only 6 consecutive hours. On day 2, the driver never took a minimum of 30 consecutive minutes off-duty, even after remaining in the driver's seat for more than 8-hours. At 8:00 p.m. the driver was in violation of the 30-minute break provision and remained in violation for the remainder of the day.

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 5-hour sleeper-berth period is included in the 14 hour calculation because it was less than 8 hours). Though the driver was not eligible to drive a CMV after midnight, he or she was able to continue working on duty without violation, as long as no driving took place (which was done for 1 hour). The driver violated the 14 hour rule by driving a CMV at 1:00 a.m. Then, after 10 consecutive hours off duty, the 14 hour calculation point moved to noon on Day 2, at which point the driver had 14 hours available to work again.

Logging Example #19

Day 1

Day 2

Violations: 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.

Explanation - 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.

Explanation - 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.

Explanation - 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.

Logging Example #20

Day 1

Day 2

Violations: There is an 11 hour rule violation from 5:00 a.m. - 7:00 a.m. on Day 2.

Explanation - 11 Hour Limit: After 10 hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had 3 hours remaining, and exceeded the limit, by 2 hours, starting at 5:00 a.m. Then, 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 (in this case, 8), 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 2:00 a.m. on Day 2. Between 2:00 a.m. and 3:00 p.m., the driver had 5 hours of driving, so at 3:00 p.m. on Day 2 there were 6 hours remaining, which the driver used by 9:00 p.m. Because the driver then took at least 2 consecutive hours off duty, he or she accumulated another 10 hours of rest in two separate, qualifying periods totaling 10 hours. This moves the calculation point again, to 3:00 p.m. on Day 2, and at 11:00 p.m. on Day 2 the driver has 5 hours of driving time remaining.

Explanation - 30 Minute Break: On Day 1, the driver required a 30 minute break at 6:00 p.m. in order to continue driving. But since the driver went into the sleeper berth and stayed there for 8 hours, the requirement was no longer needed. On Day 2, the driver never stayed on duty long enough to require a 30 minute break.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 10:00 a.m. on Day 1. The driver accumulates 8 hours of driving time by 6:00 p.m. before entering the sleeper berth. Because any sleeper berth period of at least 8 (but less than 10) consecutive hours is excluded from the 14 hour calculation, the driver accumulated just 13 hours by 7:00 a.m. on Day 2. The driver then met the requirements for the split sleeper berth provision, so the calculation point moves to the end of the first qualifying break, or 2:00 a.m. on Day 2. Starting from there, the driver accumulated 11 hours by 9:00 p.m. on Day 2. The driver again met the requirements for the split sleeper berth provision by getting 2 hours of rest, so the calculation point moves to 3:00 p.m. and the driver remains in compliance.
