Good Luck!

EOBR's are required to automatically record which of the following?
  • All of these answers are correct
  • Engine use
  • Road speed
  • Miles driven
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Manufacturers of EOBRs must certify that their devices meet the minimum requirements. This includes a requirement that an EOBR must be mechanically or electronically connected to the truck to automatically record, at a minimum, engine use, road speed, miles driven, the date, and time of day. Drivers enter other information required to complete the hours-of-service records. The vast majority of EOBRs now use GPS tracking to meet these requirements.

TruckingTruth's Advice:

Most EOBRs are integrated within satellite communication systems that drivers and dispatchers use to communicate with each other.

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

  • Yes, the example is legal
  • No, the driver exceeded his legal drive time by 30 minutes
  • No, the driver did not satisfy the 30 minute break requirement
  • No, the driver exceeded his 14 hour on duty time
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 does DOT stand for?
  • Department of Timekeeping
  • Department of Transportation
  • Diary of Time
  • Days of On-Duty Time
This is a question from page 92 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

As a truck or bus driver, you'll be required to record and abide by all working and driving limitations which were created by the Department of Transportation (DOT). The rules govern a commercial driver's working and resting hours and are referred to as Hours of Service (HOS) Regulations. In this section we will guide you through the HOS regulations and teach you the best methods of properly recording your hours.

TruckingTruth's Advice:

Everyone in trucking refers to the Department of Transportation as "The DOT." If you don't know this, you'll sound like a rookie. You don't want that, do ya!?

Which log below contains at least one violation?

Day 1

Day 2

  • Both day 1 and day 2
  • Day 1
  • 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.

What happens if you spend 8 hours in the sleeper berth?
  • Those hours will not count as part of your 14 hour on duty time, and therefore, would allow you to extend the time during which you could use your maximum 11 hours of driving
  • You will regain 8 hours on your 14 hour on duty time
  • Spending 8 hours in the sleeper berth will completely reset your 14 hour on duty time and your 11 hour driving time
  • Spending 8 hours in the sleeper berth will completely reset your 60/70 hour on duty clock
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.

TruckingTruth's Advice:

Basically, when you take an 8 hour break in the sleeper berth, your time simply extends. You can't reset your hours completely, but those 8 hours will not count against your 14 hour on duty time.

In other words, let's say you have the following hours remaining:

  • 14 hour duty clock: 7 hours
  • 11 hour driving clock: 6 hours

If you go into the sleeper berth, in 8 hours you will still have the same time remaining.

If you had taken 10 consecutive hours off instead, your 14 and 11 hour limits would have completely reset. That's why the 8 hour sleeper berth rule should only be used when necessary. Normally this rule is used when it is necessary in order to make a delivery legally and on-time.

What violation occurs on the below example?

Day 1

Day 2

  • There is an 11 hour violation as well as a 30 minute break violation
  • There is an 11 hour rule violation only
  • There is a 14 hour rule violation only
  • There is an 11 hour rule violation as well as a 14 hour rule 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.).

What violation has occurred on the below log?

  • There is an 11 hour rule violation
  • There is a 30 minute break violation
  • There is a 14 hour rule violation
  • There is no violation on this log
This is a question from page 98 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Violations: There are no violations in this example.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of drive time available starting at 1:00 a.m. The driver drove between the hours of 1:00 a.m. and 6:00 a.m. (5 hours), then again between the hours of 7:00 a.m to 10:00 a.m. (3 hours) and finally between the hours of noon to 2:00 p.m (2 hours). Since the driver was allwed a total of 11 hours of drive time but only drove 10 hours (5 + 3 + 2), no violation occurred.

Explanation - 30 Minute Break: After 10 consecutive hours off duty, the driver went on duty at midnight. At that point, the driver could perform driving duties until 8:00 a.m. before a 30 minute break off duty would be required to continue any driving tasks. After driving for 5 hours (on duty for a total of 6 hours) the driver fulfilled the break requirement by spending 1 hour off duty between the hours of 6:00 a.m. and 7:00 a.m. Starting at 7:00 a.m. the driver was allowed to continue driving for the remainder of his/her available 11 and 14 hour limits.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at Midnight. At 2:00 p.m., the driver had reached the end of the 14 hour window (10 hours driving; 3 hours on duty; 1 hour off duty). The driver may not drive a CMV once he or she has reached the end of the 14 consecutive-hour period and in this example, the driver goes off duty for the required 10 consecutive hours starting at 2:00 p.m.

Quote From Page 0 Of The Illinois CDL Manual:

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.
