Good Luck!

What hours must your logbook show?
  • Only the hours you are on duty or driving
  • Only your resting hours
  • All 24 hours of every day
  • The logbook only needs to show a 12 consecutive hour time frame each day
This is a question from page 97 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

You must 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.

TruckingTruth's Advice:

All logbooks must show 24 hours for each day and each hour must be accounted for. Even if you were off duty for an entire 24 hour stretch, you must log the entire day as off duty.

What violation has occurred on the below log?

  • There is an 11 hour rule violation
  • There is no violation on this log
  • There is a 14 hour rule violation
  • There is a 30 minute break violation
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.

If you're able to arrive early for a delivery, you should:
  • Call ahead and ask the customer for an earlier appointment time
  • Tell your dispatcher there is too much time on the load and ask for another dispatch
  • Wait until the last available time to start heading to your delivery location
  • Never show up early to a customer location
This is a question from page 107 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

If you are picking up or delivering a load and have some time to spare on either the pick up or delivery times, call ahead and see if you can arrive early. This is an excellent way to ensure you complete the load quickly and become available for the next one. Customers are used to getting phone calls from truck drivers. Don't be afraid to call ahead.

Which statement below accurately describes the 11 hour driving limit?
  • You can only drive between the hours of 9am to 8pm each day
  • You may not perform any on duty work (driving or non-driving duties) after 11 consecutive hours have passed since you began your work day
  • Once you have driven a total of 11 hours in any 14 consecutive hours of on duty time, you have reached the driving limit and must be off duty for another 10 consecutive hours before driving your truck again
  • You must take 11 consecutive hours off duty before you are allowed to drive
This is a question from page 93 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The 11 Hour Driving Limit

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.

TruckingTruth's Advice:

After taking 10 consecutive hours (or more) off duty, you will have a fresh 11 and 14 hour clock. As soon as you begin working (pre-trip inspection, fueling, loading / unloading cargo, driving, etc.) your 14 hour clock starts. Within those 14 hours, you are allowed to actually drive for 11 of those hours. The remaining 3 hours can be used for other non-driving duties (loading / unloading cargo, performing maintenance duties, etc.) as well as taking breaks. The 11 hour clock will only count down if you are actually driving. In other words, the 11 hour clock can be paused. So if you want to take a 30 minute break for lunch, you may do so and stop the 11 hour driving limit. However, your 14 hour clock can't be stopped. If you reach the end of your 14 hour day and still have driving time remaining on the 11 hour clock, you still must stop driving. After 14 hours since you started your day, or after 11 hours of driving (whichever comes first), you can't drive again until you've taken 10 consecutive hours off.

Why Do HOS Regulations Exist?
  • All of these answers are true
  • To keep drivers from sitting too long between load assignments
  • To ensure drivers are being paid at least minimum wage
  • To reduce accidents caused by driver fatigue
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.

Which of the following is considered off duty time?
  • Time inspecting or servicing your truck
  • Anytime you aren't driving
  • When you are relieved of all duty and responsibility for performing work
  • Time spent doing paid work for anyone who is not a motor carrier
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 Off Duty Time

By understanding the definition of on duty time, you will get a good idea of what is considered off duty time. In order for time to be considered off duty, you must be relieved of all duty and responsibility for performing work. You must be free to pursue activities of your own choosing and be able to leave the place where your vehicle is parked.

If you are not doing any work (paid or unpaid) for a motor carrier, and you are not doing any paid work for anyone else, you may record the time as off duty time.

Personal Use Of A Commercial Motor Vehicle

It is possible that occasionally you may not use a truck in commerce at all. You may be moving your personal belongings to a new house or, as a hobby you may be taking your horses to a horse show. As long as the activity is not in support of a business, you are not operating in commerce.

If you are not operating your truck in commerce, you are not subject to the hours of service regulations.

TruckingTruth's Advice:

As long as you aren't doing anything related to your job and you aren't earning any sort of compensation from anyone, you can log off duty. You also must be completely relieved of all duty and responsibility for performing work.

What happens if an EOBR malfunctions?
  • A broken EOBR will require you to shut down immediately and remain off-duty until the EOBR can be repaired
  • 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
  • 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.

Which day below contains at least 1 violation?

Day 1

Day 2

  • Day 2 contains at least 1 violation
  • Both days contain violations
  • Day 1 contains at least 1 violation
  • There are no violations on either day
This is a question from page 104 - 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.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 2:00 a.m. on Day 1. The driver used those 11 hours by 3:00 p.m. 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 and another break of at least 2 consecutive hours, 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 9:00 a.m. on Day 1. Starting the calculation from there, the driver accumulated another 11 hours of driving by 4:00 a.m. on Day 2. By 6:00 a.m. on Day 2, the driver accumulated another pair of qualifying breaks totaling at least 10 hours. This moves the calculation point again, to the end of the first of the two breaks, or 11:00 p.m. on Day 1. From there, the driver accumulated another 11 hours of driving by noon on Day 2. This pattern continued, with no 11 hour violations.

Explanation - 30 Minute Break: A 30 minute break is only required when a driver wants to drive a CMV after being on duty for longer than 8 hours without a 30 consecutive minute off duty break. On both days in this example, the driver was never on duty long enough to require a 30 minute break.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 2:00 a.m. on Day 1. The driver accumulates 13 hours by 3:00 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 9:00 a.m. on Day 1. So at 11:00 p.m. on Day 1, the driver had accumulated 6 hours (any sleeper berth period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation). By 6:00 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 duty limit. This moves the calculation point again, to the end of the first of the two breaks, or 11:00 p.m. on Day 1. From there, the driver accumulated 13 of 14 hours by noon on Day 2 (any sleeper berth period of less than 8 hours is included in the 14 hour calculation). This pattern continued, with no violations.
