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 below accurately describes the 11 hour driving limit?
  • You can only drive between the hours of 9am to 8pm each 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 may not perform any on duty work (driving or non-driving duties) after 11 consecutive hours have passed since you began your work day
  • 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 should you always plan on arriving to your destination as quickly as possible?
  • Many customers will give you an earlier appointment time if you show up early, even if they said they wouldn't over the phone
  • Many things can go wrong along the way
  • All of these are reasons to arrive at your destination as quickly as possible
  • You might be able to sneak in a 34 hour restart

Quote From Page 0 Of The Illinois CDL Manual:

Arrive early

It's good practice to always arrive at your destination as quickly as possible. Many things can go wrong along the way. It would be a shame to take your time, only to have something slow you down later on. Always get as close to your customer as possible right away. If you have time to waste, you should waste it near the customer. Far too many drivers lose out on miles because they had a problem en-route and wasted too much time along the way. Not to mention, many customers will give you an earlier appointment time if you show up early, even if they said they wouldn't over the phone.

Is the below example a completed 34 hour restart?

Day 1

Day 2

  • No, the driver didn't spend enough time off duty to complete the restart
  • None of these answers are correct
  • Yes, the restart has been completed
  • No, the driver didn't complete two rest periods between 1:00 a.m. and 5:00 a.m.

Quote From Page 0 Of The Illinois CDL Manual:

Day 1





Day 2







Explanation - 34 Hour Restart: In this example, the 34 hour restart has been completed successfully. The driver took 34 consecutive hours off duty from 1:00 a.m. on Day 1 until 5:00 a.m. on Day 2. Not only does this satisfy the 34 hour consecutive break requirement, but it also satisfies the two required break periods between 1:00 a.m. and 5:00 a.m. At 5:00 a.m. on Day 2, the drivers 34 hour break was completed and his/her 70 hour limit would reset.

  • Day 2 at 2:00 a.m.
  • Day 2 at 4:00 p.m.
This is a question from page 102 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There is an 11 hour rule violation from 5:00 a.m. - 7:00 a.m. on Day 2.

Explanation - 11 Hour Limit: After 10 hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had 3 hours remaining, and exceeded the limit, by 2 hours, starting at 5:00 a.m. Then, 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 (in this case, 8), 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 2:00 a.m. on Day 2. Between 2:00 a.m. and 3:00 p.m., the driver had 5 hours of driving, so at 3:00 p.m. on Day 2 there were 6 hours remaining, which the driver used by 9:00 p.m. Because the driver then took at least 2 consecutive hours off duty, he or she accumulated another 10 hours of rest in two separate, qualifying periods totaling 10 hours. This moves the calculation point again, to 3:00 p.m. on Day 2, and at 11:00 p.m. on Day 2 the driver has 5 hours of driving time remaining.

Explanation - 30 Minute Break: On Day 1, the driver required a 30 minute break at 6:00 p.m. in order to continue driving. But since the driver went into the sleeper berth and stayed there for 8 hours, the requirement was no longer needed. On Day 2, the driver never stayed on duty long enough to require a 30 minute break.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit begins at 10:00 a.m. on Day 1. The driver accumulates 8 hours of driving time by 6:00 p.m. before entering the sleeper berth. Because any sleeper berth period of at least 8 (but less than 10) consecutive hours is excluded from the 14 hour calculation, the driver accumulated just 13 hours by 7:00 a.m. on Day 2. The driver then met the requirements for the split sleeper berth provision, so the calculation point moves to the end of the first qualifying break, or 2:00 a.m. on Day 2. Starting from there, the driver accumulated 11 hours by 9:00 p.m. on Day 2. The driver again met the requirements for the split sleeper berth provision by getting 2 hours of rest, so the calculation point moves to 3:00 p.m. and the driver remains in compliance.

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 no violation
  • There is a 14 hour rule 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.

What does HOS stand for?
  • Hometime Optimization System
  • Hours of Service
  • Hours on Site
  • Highway Organization System
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.

TruckingTruth's Advice:

During the rest of this program, we will be referencing HOS instead of saying Hours of Service every time. As an industry standard, HOS always stands for Hours of Service and the vast majority of people in the trucking industry are very familiar with the term HOS.

When can your logbook be inspected?
  • At any weigh station your logbook can be checked for any reason
  • All of these answers are correct
  • During a random traffic stop by any police officer
  • Your carrier can audit your logbook anytime
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. Not only do carriers want to ensure their drivers are being safe on the roadways, but carriers often receive audits from DOT officials and can be heavily fined if too many drivers have violations on their logs. 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 (discussed later) has forced carriers to crack down on HOS violations even more.

TruckingTruth's Advice:

Your logbook can be checked virtually anytime. Never press your luck. Make sure your logbook is legal and up to date all the time.
