  • If you take at least two 17 hour breaks within an 8 day period, all your hours will reset
  • After you have been on duty for 34 hours, you must take a 70 hour break

The 34 Hour Restart

The regulations allow you to "restart" your 60 or 70 hour clock calculations after having at least 34 consecutive hours off duty. In other words, after you have taken at least 34 hours off duty in a row, you have the full 60 or 70 hours available again. You would then begin counting hours on the day of the restart and not go back the full 7 or 8 days.

TruckingTruth's Advice:

If you are planning to become an OTR truck driver, you will use the 8 day / 70 hour limit. That means, you are unable to drive once you've been on duty for more than 70 hours within an 8 day period. If you've worked close to that limit, you may want to "reset" the 70 hour limit. The only way to completely reset your 70 hour limit is to take an extended amount of time off duty. If you take 34 consecutive hours off without driving or performing on duty tasks, your 70 hour limit will reset.

At what time does a violation occur on this log?

  • 9:00 p.m.
  • 7:00 p.m.
  • 10:00 p.m.
  • 8:00 p.m.
This is a question from page 104 - click here to look up the answer

Quote From Page 0 Of The Illinois 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.

Who enforces HOS regulations?
  • DOT Officials
  • Police Officers
  • Carriers
  • All of these answers are correct
This is a question from page 92 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Who Enforces HOS Regulations?

Law enforcement:

Generally, DOT officers are the ones who enforce HOS rules, although any police officer may inspect a driver's logbook. Individual states are responsible for maintaining weigh stations where drivers are pulled in for random vehicle and logbook inspections. Drivers may also be pulled over for random checks by police officers or DOT officials at any time and have their logbooks inspected. While it's not a frequent occurrence, chances are your logbook will be checked every now and then. Be ready for it at all times!

Carriers:

In addition to law enforcement and DOT officials, most carriers have their own company policies regarding logbooks. A drivers logs are frequently reviewed by internal auditors for discrepancies or violations. A driver with too many violations might be warned, disciplined, or terminated (terminating a driver usually only occurs after several violations). The increased use of electronic logging devices has forced carriers to crack down on HOS violations even more.

TruckingTruth's Advice:

You should always be prepared for a random inspection. Your logs must always be current. If you get pulled into a weigh station or get pulled over for a random inspection, which does happen, and your logbook is not current, you will be cited for a violation.

The carrier you work for will also have logbook auditors. Companies themselves are required to keep driver logs for a period of time and receive random audits from the DOT. If too many of their drivers have logbook violations, the company can be fined or otherwise penalized. They have an interest in passing those audits so if you cause too many problems for them, they will take action.

What time does a 14 hour rule violation occur?

  • At 5:00 p.m.
  • At 6:00 p.m.
  • At 3:00 p.m.
  • There is no 14 hour rule violation in this example
This is a question from page 104 - click here to look up the answer

Quote From Page 0 Of The Illinois 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.

Which log below contains at least one violation?

Day 1

Day 2

  • Day 1
  • Both day 1 and day 2
  • Day 2
  • There are no violations in this example
This is a question from page 99 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There is a 30 minute break violation in this example from 6:00 p.m. - 10:00 p.m and 11:00 p.m. to Midnight on Day 1.

Explanation - 11 Hour Limit: On Day 1, the driver drove from 11:00 a.m. to 4:00 p.m. (5 hours) then again from 6:00 p.m. to 10:00 p.m. (4 hours) and finally from 11:00 p.m. to Midnight (1 hour). Therefore, the driver drove for a total of 10 hours on Day 1 (5 + 4 + 1) and never violated the 11 hour limit. On Day 2, the driver only drove between the hours of 10:00 a.m. and 2:00 p.m. for a total of 4 hours, thus, no violation of the 11 hour limit occurred.

Explanation - 30 Minute Break: On Day 1, the calculation point for the 30 minute break provision is 10:00 a.m. In order to continue driving beyond 6:00 p.m. (8 hours after the initial starting calculation point) a 30 minute break off duty must be taken. Since the driver never took a break off duty, a 30 minute break violation occurred between the hours of 6:00 p.m. and 10:00 p.m. The driver then went on duty between the hours of 10:00 p.m. and 11:00 p.m., before violating the 30 minute break provision again by driving a CMV between 11:00 p.m. and Midnight. In order to remain legal, the driver should have taken his/her 30 minute break by 6:00 p.m. On Day 2, the driver was only on duty for a total of 7 consecutive hours which would not require a 30 minute break.

Explanation - 14 Hour Limit: After taking 10 consecutive hours off duty, the driver had 14 hours available beginning at 10:00 a.m. on Day 1. The driver switched into the sleeper berth at Midnight, exactly 14 hours later. Since the driver remained in the sleeper for 10 consecutive hours, the 14 hour limit reset and the new starting calculation point was then 10:00 a.m. on Day 2. The driver only remained on duty from the hours of 10:00 a.m. until 5:00 p.m. for a total of 7 hours of on duty time on Day 2. The driver remined legal on both days and no violation occurred.

Quote From Page 0 Of The Illinois CDL Manual:

Logging Example #23

Day 1

Day 2

Violations: There is a 30 minute break violation from 6:00 p.m. to 7:00 p.m. on Day 1. There is also a 14 hour rule violation on Day 2 from 5:00 p.m. - 9:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the initial calculation point for this driver's 11 hour driving limit is 10:00 a.m. on Day 1. The driver drove 9 hours that day before taking 8 hours off duty in the sleeper berth, leaving 2 hours of driving time available at 3:00 a.m. on Day 2 (the 8 hour sleeper berth period does not result in extra driving time). The driver used those 2 hours and reached the 11 hour limit at 5:00 a.m. when he or she had to stop driving. Then the driver went off duty for at least 2 consecutive hours (8 hours off duty total) to take advantage of the sleeper berth provision. He or she 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. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 3:00 a.m. on Day 2. Between 3:00 a.m. and 1:00 p.m. on Day 2, the driver had 2 hours of driving, so at 1:00 p.m. there were 9 hours of driving remaining (11 - 9) and the driver stayed within that limit.

Explanation - 30 Minute Break: On Day 1, the driver had been on duty since 10:00 a.m. and was required to take at least a 30 minute break before driving beyond 6:00 p.m. Therefore, the driver was in violation of the 30 minute break provision from 6:00 p.m. to 7:00 p.m. on Day 1. On Day 2, the driver was on duty for a total of 8 hours between 1:00 p.m. and 9:00 p.m. Since the driver went off duty at 9:00 p.m., exactly 8 consecutive hours after first going on duty (driving), no violation occurred.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit starts at 10:00 a.m. on Day 1, but does not include the 8-hour sleeper-berth period (7:00 p.m. on Day 1 to 3:00 a.m. on Day 2) because any sleeper period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation. So by 5:00 a.m. on Day 2, the driver used 11 hours driving and had 3 hours remaining out of the 14 hours allowed. But at 5:00 a.m., the driver went off duty for at least 2 hours, making him or her eligible for the split sleeper berth provision. This moves the calculation point for the 14 hour limit to the end of the first of the two rest periods used to obtain 10 hours off duty, or 3:00 a.m. on Day 2. consecutive hours after 3:00 a.m. is 5:00 p.m., when this driver should have stopped driving but did not.

NOTE: Any period of off duty time less than 10 hours (such as this driver's 8 hour off duty break on Day 2) is included in the 14 hour calculation. Also note that the driver's 8 hour sleeper berth period allowed him or her to drive during the 18th and 19th hour after first coming on duty, but it did not by itself give the driver additional driving time beyond 11 hours.

To remain in compliance, the driver should have stopped driving at 5:00 p.m. on Day 2. The driver would have remained in compliance if he or she had gone off duty for 10 hours on Day 2 instead of just 8, or if he or she had spent those 8 hours in a sleeper berth.

Which of the following is considered on duty time
  • All time inspecting or servicing your truck, including fueling
  • All time loading and unloading your truck
  • All of these are considered on duty time
  • All driving time
This is a question from page 94 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

What Is Considered On Duty Time?

The 60 / 70 hour limit is based on how many hours you work over a 7 or 8 day period. Just what kind of work is considered on duty time? It includes all time you are working or are required to be ready to work, for any employer. Here are some specific activities which are considered to be on duty time:

  • All time spent at a plant, shipping / receiving facility, terminal, or other facility of a motor carrier, unless you are in your sleeper berth or have been relieved of all work related responsibilities.
  • All time inspecting or servicing your truck, including fueling it and washing it.
  • All driving time.
  • All other time in a truck unless you are resting in a sleeper berth.
  • All time loading, unloading, supervising, or attending your truck; or handling paperwork for shipments.
  • All time spent providing a breath, saliva, hair, or urine sample for drug / alcohol testing, including travel to and from the collection site.
  • All time spent doing any other work for a motor carrier, including giving or receiving training and driving a company car.
  • All time spent doing paid work for anyone who is not a motor carrier, such as a part-time job at a local restaurant.

The bottom line is that on duty time includes all time you are working for a motor carrier, whether paid or not, and all time you are doing paid work for anyone else.

What violation occurs on the below example?

Day 1

Day 2

  • There is an 11 hour rule violation as well as a 14 hour rule violation
  • There is an 11 hour rule violation only
  • There is a 14 hour rule violation only
  • There is an 11 hour violation as well as a 30 minute break violation
This is a question from page 99 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There is a violation of the 11 and 14 hour rules at 2:00 p.m. on Day 1.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty prior to the start of Day 1, the driver had 14 hours of on duty time available and 11 hours of driving time available, starting at Midnight on Day 1. The driver performed driving duties during the following times on Day 1:

  • 1:00 a.m. to 5:00 a.m. (4 Hours)
  • 6:00 a.m. to 10:00 a.m. (4 Hours)
  • 11:00 a.m. to 3:00 p.m. (4 Hours)

Given the above breakdown of driving hours, we can see that the driver had operated a CMV for 12 total hours (4 + 4 + 4) on Day 1 without taking a 10 consecutive hour break. So on Day 1, the 11 hour driving limit has been exceeded and a violation occurred at 2:00 p.m. On Day 2, the driver began driving at 1:00 a.m. after taking 10 consecutive hours off duty. This reset the drivers 11 and 14 hour limits, bringing the new calculation point to 1:00 a.m. After driving for 5 hours between 1:00 a.m. and 6:00 a.m., the driver never returned to driving again. Therefore, no violation occurred on Day 2.

Explanation - 30 Minute Break: On Day 1, the driver went on duty at midnight and would therefore need a minimum of a 30 minute break off duty in order to drive beyond 8:00 a.m. However, a 1 hour break was completed at 5 a.m. satisfying the 30 minute break provision and allowing the driver to continue driving without violating the break provision. On Day 2, the driver went on duty at 1:00 a.m. which is the new starting calculation point after taking a 10 consecutive-hour break. In order to continue driving beyond 9 a.m. (8 hours after the starting calculation point), the driver would need to take a minimum of 30 minutes off duty or in the sleeper berth. However, at 6 a.m. the driver switched to on duty and remained there until switching to the sleeper berth at 11 a.m. The driver was allowed to be on duty beyond 9 a.m. and only driving would have been prohibited. Since the driver did not operate a CMV for the rest of the day, no violation occurred.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty prior to the start of Day 1, the driver had 14 hours of on duty time available starting at Midnight on Day 1. While the driver would have been allowed to remain on duty indefinitely, no driving was allowed after 14 hours (2:00 p.m.).
