Good Luck!

If you have used up all of your 14 hour on duty time, how many hours would you regain after an 8 hour break in the sleeper berth?
  • Your 14 hour limit would reset
  • None of these answers are correct
  • You would regain half of your hours (7 hours total)
  • You will still have no hours remaining

Quote From Page 0 Of The Illinois CDL Manual:

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.

TruckingTruth's Advice:

An 8 hour break will never add more hours to any of your limits. Rather, an 8 hour break simply extends your time by not counting the break against your 14 hour duty clock. The concept is confusing, but it's actually very simple. Here are some examples.

  • If you have 5 hours remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 5 hours remaining.
  • If you have 1 hour remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 1 hour remaining.
  • If you have 0 hours remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 0 hours remaining.
  • As you can see, you will not gain any hours back after taking an 8 hour break. Instead, your available hours have simply been extended.

    So why would you ever want to take an 8 hour break instead of a 10 hour break? Here's an example:

    Let's say you have a delivery in the morning, but you are not allowed to park at your delivery location overnight. Instead, you have to stop at a truck stop 20 miles away to park for the night. In order to make your appointment on time, you must leave after only resting for 8 hours. If that's the case, you can still make the delivery on time by taking an 8 hour break instead of a full 10 hour break.

    Little situations like this will come up frequently as a truck driver. That's why it's so important to understand these little loopholes and tricks. We'll go through more examples later on in this section, but try to have a full understanding of the 10, 8 and split sleeper rules.

What time does a 14 hour rule violation occur?

  • There is no 14 hour rule violation in this example
  • At 5:00 p.m.
  • At 3:00 p.m.
  • At 6:00 p.m.

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.

What happens if an EOBR malfunctions?
  • The driver is expected to use an "honor system" until the issue can be repaired
  • Drivers are still required to have a paper logbook in the truck in case of a malfunction
  • A broken EOBR will require you to shut down immediately and remain off-duty until the EOBR can be repaired
  • Drivers can call their carrier and have each duty-status changed remotely
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

What if my EOBR malfunctions?

As with any electronic device, your EOBR may malfunction or become completely unusable at times. You are still required to have a paper logbook in the truck in case of a malfunction. It is your responsiblity to ensure your paper logbook accounts for all time your EOBR has been down.

TruckingTruth's Advice:

Remember, during a random logbook inspection, you may be asked to show that you have a paper logbook in case of an EOBR malfunction.

What does EOBR stand for?
  • Electronic Occurrence and Break Recorder
  • Enforcement of Break Rules
  • Electronic On-Board Recorder
  • Electric Orientation and Break Recorder
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Many motor carriers have installed electronic devices in their trucks to help accurately record hours of service information. If such a device meets the requirements of the safety regulations, it is called an Electronic On-Board Recorder (EOBR), and may be used in place of a paper logbook.

TruckingTruth's Advice:

EOBRs are slowly becoming the industry standard. If you are hired on with any large carrier, chances are very high that you will be using an EOBR. Many small companies still use paper logbooks, but EOBRs will soon take over.

Which statement below is true?
  • An EOBR may be used without creating any paper copies
  • EOBRs are declining in usage
  • EOBRs must store at least the previous 3 days of log information
  • EOBRs must be capable of printing a log sheet
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The EOBR device must be capable of displaying or printing for enforcement officers the times of duty status changes and other required information. It must also store this information for the prior 7 days. An EOBR may be used without creating any paper copies of logs by transmitting the data electronically to the carrier, or it may be used to print copies of the logs that would be signed by the driver and mailed to the carrier.

What Is The Future Of EOBRs

Even 5 years ago, the vast majority of major trucking carriers relied on paper logs. But the DOT and FMCSA have begun a historic crackdown on enforcing and regulating, among other things, HOS rules. Violations now effect both the drivers record as well as the carriers safety rating. We are at a turning point where it now makes financial sense for trucking companies to switch over from using paper logs to EOBRs. These electronic recording devices are here to stay and will only grow in usage as time goes on. In fact, on January 31, 2011, the FMCSA proposed a rule that would require Electronic On-Board Recorders for interstate commercial truck and bus companies.

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.

What violation has occurred at 8:00 a.m. on Day 2?

Day 1

Day 2

  • There is an 11 hour rule violation
  • There is an 11 hour and 14 hour rule violation
  • There is a 14 hour rule violation
  • There is no violation
This is a question from page 101 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There are 11 and 14 hour rule violations from 8:00 a.m. - 1:00 p.m. on Day 2.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver was eligible to drive for up to 11 hours beginning at 2:00 a.m. on Day 1. The driver reached the 11 hour driving limit at 3:00 p.m. on Day 1 and did not obtain another 10 hour break before driving again at 8:00 a.m. on Day 2, thus violating the 11 hour limit. The driver then obtained 8 consecutive hours in a sleeper berth, which, combined with the earlier 7 1/2 hour sleeper berth period, made the driver eligible for the split sleeper berth provision which means 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 11 hour calculation point to the end of the first of the two qualifying breaks, or 5:00 a.m. on Day 2. Between 5:00 a.m. and 9:00 p.m., the driver had 5 hours of driving, so at 9:00 p.m. on Day 2 there were 6 hours remaining, and there were no further 11 hour rule violations.

Explanation - 30 Minute Break: The driver was never on duty or driving for enough consecutive hours which would make 30 minute break mandatory, therefore the 30 minute break provisions does not apply in this example.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at 2:00 a.m. on Day 1. The 14 hour limit was reached at 4:00 p.m. on Day 1. Without a valid 10 hour break, the hours continued to accumulate into Day 2, and the driver violated the 14 hour rule by driving at 8:00 a.m. The driver then went into the sleeper berth for 8 consecutive hours, which enabled him or her to take advantage of the split sleeper berth provision. This moves the 14 hour calculation point to 5:00 a.m. on Day 2, the end of the first of the two qualifying breaks. Counting forward from there, the 8 hours from 5:00 a.m. to 1:00 p.m. are included in the calculation, but the 8 hour sleeper berth period is excluded. Therefore, at 9:00 p.m. on Day 2, the driver had 6 hours remaining and had no further violations of the 14 hour rule.

To remain in compliance: The driver should have remained in the sleeper berth until 5:30 a.m. on Day 2, thus moving the calculation point to 9:00 p.m. on Day 1. Or, at 9:00 p.m. on Day 1, the driver should have remained in the sleeper berth instead of going on duty for 30 minutes.

How current must your logbook be?
  • You must show what time you went on duty, then the rest of the log can be filled out when you go off duty for the day
  • Your current day log must be filled out within' 48 hours
  • Logs must be filled out at the end of each driving day
  • It must show your last duty change
This is a question from page 96 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The current days log must be current to your last change of duty status.

TruckingTruth's Advice:

Quite a few truck drivers are written citations or are placed out of service because their logbooks aren't current. These citations are the result of laziness. You must be current to your last duty status change. So if you are randomly stopped by a police officer and your logbook is checked, it should when you last changed into the driving status.
