Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There is a 14 hour rule violation from 5:00 a.m. - 8:00 a.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 at 5:00 a.m. on Day 1. Before obtaining another 10 consecutive hour break (beginning at 9:00 a.m. on Day 2), he or she drove for only 7 hours, well within the limit.

Explanation - 30 Minute Break: All requirements for the 30 minute break provision were met. The driver never drove after being on duty for longer than 8 consecutive hours without at least 30 consecutive minutes spent off duty.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 5:00 a.m. on Day 1.

The 14 hour calculation includes:
  • All off duty time of less than 10 consecutive hours;
  • All sleeper-berth time of less than 8 hours; and
  • All on duty and driving time.

Therefore, the driver reached the 14 hour limit at 7:00 p.m. on Day 1, and the violation began when the driver drove a CMV at 5:00 a.m. on Day 2.

NOTE: Although this driver had 15½ hours off duty between 9:00 a.m. on Day 1 and 1:00 a.m. on Day 2, that off duty time was interrupted by a period of 30 minutes on duty (3:00 p.m. on Day 1). Therefore, both the 6-hour sleeper-berth period and the 9½-hour off duty period are included in the 14 hour calculation (the calculation point does not change from 5:00 a.m. on Day 1). In addition, note that the driver can legally work after reaching the 14 hour limit, but cannot drive a commercial motor vehicle.

To remain in compliance, the driver should not have gone on duty from 3:00 p.m. - 3:30 p.m. on Day 1, or should have remained off duty from 1:00 a.m. - 1:30 a.m. on Day 2, in order to get 10 consecutive hours of off duty time.

Which statement below is true?
  • EOBRs are declining in usage
  • An EOBR may be used without creating any paper copies
  • EOBRs must be capable of printing a log sheet
  • EOBRs must store at least the previous 3 days of log information
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.

Is the following example within legal HOS limits?

- A trucker starts driving at 12:00pm

- At 5pm the driver takes a 1 hour break

- At 6pm the driver begins driving again

- At 11:30pm, the driver shuts down and goes off duty for 10 consecutive hours

  • No, the driver exceeded his 14 hour on duty time
  • Yes, the example is legal
  • No, the driver did not satisfy the 30 minute break requirement
  • No, the driver exceeded his legal drive time by 30 minutes
This is a question from page 93 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

During the 14 consecutive hour on duty period, you are only allowed to drive your truck for up to 11 total hours. Once you have driven a total of 11 hours, you have reached the driving limit and must be off duty for another 10 consecutive hours before driving your truck again.

There are times when you will be required to take a 30 minute break. If you have been on duty for more than 8 consecutive hours without at least 30 minutes off duty, you are not allowed to operate a CMV until a 30 minute break is taken. You may perform on duty tasks but you cannot drive.

TruckingTruth's Advice:

Let's go through the example together:

Beginning the day:

In this hypothetical situation, a driver begins his day at 12pm. At that point, both his 14 hour on duty clock and 11 hour driving clock have started.

Taking a break

When the driver takes his 1 hour break, his 11hr clock stops. At this point, since he is no longer driving, only his 14 hour clock continues to run. This break also satisfies the 30 minute break provision. So far, here's how his time looks:

  • 14 hour clock: 9 hours remaining (will be 8 hours remaining once his break is complete).
  • 11 hour clock: 6 hours remaining (will remain 6 hours throughout his entire break).
Resume driving:

So, after the driver takes his 1 hour break, he still has 9 hours on his 14 hour on duty clock and 6 hours on his 11 hour driving clock remaining. Since he took 1 hour off duty, he now has 8 more consecutive hours that he can drive without taking a 30 minute break off duty.

Shutting down:

It has now been 5.5 hours since the driver took his break. So let's look at our remaining hours again.

  • 14 hour clock: The driver had 8 hours remaining once he started driving again after his break and 5.5 hours have passed since then. The driver still has 2.5 hours remaining on his 14 hour on duty limit.
  • 11 hour clock: The driver had 6 hours remaining after his break. He has driven an additional 5.5 hours since then. That means the driver still has 30 minutes remaining on his 11 hour driving clock.

So yes, this driver is indeed legal! And once he takes 10 consecutive hours off, he can do it all over again.

What is the 8 day / 70 hour on duty limit?
  • None of these answers are correct
  • You must have taken at least 70 hours off during the previous 8 days in order to drive legally
  • You are not allowed to be on duty more than 70 hours within the previous 8 days
  • You are not allowed to drive after you've been on duty 70 hours in the previous 8 consecutive days
This is a question from page 93 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The 8 day / 70 hour limit:

If your company does operate vehicles every day of the week, your employer may assign you to the 70-hour/8-day schedule. This means that you are not allowed to drive after you've been on duty 70 hours in any 8 consecutive days. Once you reach the 70 hour limit, you will not be able to drive again until you have dropped below 70 hours for an 8 consecutive day period. You may do other work, but you cannot do any more driving until you get below the limit. Any other hours you work, whether they are for a motor carrier or someone else, must be added to the total.

TruckingTruth's Advice:

The 8 day / 70hr limit will restrict how much time you're allowed to be on duty during an 8 day period. So if you take a 10 hour break to reset your 11 and 14 hour clocks, but have been on duty / driving for 65 hours in an 8 day period, you will only be able to drive 5 hours.


We'll give you some more examples later on in the program. This can be a little difficult to understand, but try to understand the differences between the 11hr, 14hr, and 70hr clocks.

Which statement below is false?
  • The current day's log must be current to your last change of duty status
  • You must have a log for each day of the last 8 days
  • You never need to log your days off
  • Authorized government inspectors may check your logs at any time
This is a question from page 96 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

You are required to account for every day on your log, even days off, unless you are covered by a logbook exception on any of the days. The log must cover all 24 hours of every day.

Authorized government inspectors may check your logs at any time. You must have a log for each day of the last 8 days that you were required to log (you might have been under an exception on some of those days). The current day’s log must be current to your last change of duty status. Inspectors check your logs to see if you have violated the hours of service regulations. Violations of the hours of service regulations can result in being fined and/or placed out of service.

Why Do HOS Regulations Exist?
  • To keep drivers from sitting too long between load assignments
  • To reduce accidents caused by driver fatigue
  • To ensure drivers are being paid at least minimum wage
  • All of these answers are true
This is a question from page 92 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Why Do HOS Regulations Exist?

The purpose of HOS regulations is to reduce accidents caused by driver fatigue. Many drivers don't like being told when they can and can't drive, but as you can see in Figure 13-1 below, the risk of an accident is directly related to how many hours a driver has been behind the wheel. HOS regulations were designed so that drivers wouldn't push themselves too far and also so that carriers can't force drivers to drive beyond their limits.

Is there a 14 hour rule violation on Day 2?

Day 1

Day 2

  • Yes, at 9:00 p.m.
  • Yes, at 1:00 a.m.
  • Yes, at 7:00 a.m.
  • No 14 hour rule violation occurs
This is a question from page 100 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There are no violations in this example.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available beginning at 2:00 a.m. on Day 1. The driver used those 11 hours by 4:00 p.m. on Day 1, 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 (4:00 p.m. to Midnight on Day 1) and another break of at least 2 consecutive hours (8:00 a.m. to 10:00 a.m. on Day 1), 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 10:00 a.m. on Day 1. Starting the calculation from there, the driver accumulated another 10 hours of driving by 5:00 a.m. on Day 2. By 7:00 a.m. on Day 2, the driver accumulated another pair of qualifying breaks totaling at least 10 hours [4:00 p.m. to Midnight on Day 1 (8 hours) and 5:00 a.m. to 7:00 a.m. on Day 2 (2 hours)]. This moves the calculation point again, to the end of the first of the two breaks, or Midnight beginning Day 2. From there, the driver accumulated another 10 hours of driving by 1:00 p.m. on Day 2. The pattern of 8/2 split sleeper berth provisions continued, with no 11 hour violations.

Explanation - 30 Minute Break: On Day 1, the driver spent a total of 12 hours split between on duty and driving time. In order to continue driving beyond the 8th hour, a 30 minute break must be recorded. The calculation point on Day 1 is 2:00 a.m., so in order to continue driving after 10:00 a.m. (8 hours later), a minimum of 30 minutes must be spent off duty. In this example, the driver spent 2 hours in the sleeper berth from 8:00 a.m. to 10:00 a.m. and this satisfies the 30 minute break requirement, so no violation occurred. On Day 2, the driver first went on duty at midnight. In order to drive a CMV after 8:00 a.m. (8 hours later) a minimum of a 30 minute break off duty would be required. The driver met that requirement by taking a 2 hour break off duty (sleeper berth) break between 5:00 a.m. and 7:00 a.m. The hours spent driving between 9:00 p.m. and Midnight on Day 1 are also legal since an 8 hour break was taken between 1:00 p.m. and 9:00 p.m.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 2:00 a.m. on Day 1. The driver accumulates 14 hours by 4:00 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 10:00 a.m. on Day 1. So at Midnight leading into Day 2, the driver had accumulated 6 hours. By 7:00 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 limit. This moves the calculation point again, to the end of the first of the two breaks, or Midnight leading into Day 2. From there, the driver accumulated 13 of 14 hours by 1:00 p.m. on Day 2. This split sleeper berth pattern continued, with no 14 hour limit violations.

Which statement is true about extending the 14 hour on duty clock by using the 8 hour sleeper berth provision?
  • The 8 hours can be split between sleeper berth time and off duty time as long as those hours are consecutive
  • You can section the 8 hour break into two 4 hour segments
  • You must spend all 8 hours consecutively in the sleeper berth
  • None of these answers are correct
This is a question from page 95 - click here to look up the answer

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.
