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.

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 is a 30 minute break violation on Day 1 which occurred from 6:00 p.m. to 7:00 p.m. Then, on Day 2, there is another 30 minute break violation from 4:00 p.m. until 9:00 p.m. as well as an 11 hour rule violation from 4:00 p.m. - 9:00 p.m. and a 14 hour rule violation from 7:00 p.m. - 9:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available at 10:00 a.m. on Day 1. After driving 8 hours (3 + 2 + 3), the driver took 8 consecutive hours in the sleeper berth, which, combined with the earlier 2 consecutive hours in the sleeper from 5:00 p.m. to 7:00 p.m. on Day 1, made the driver eligible for the split sleeper berth provision. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 9:00 p.m. on Day 1. Between 9:00 p.m. on Day 1 and 8:00 a.m. on Day 2, the driver had 3 hours of driving, so at 8:00 a.m. there were 8 hours remaining (11 - 3), but he or she continued to drive for an additional 5 hours, after reaching the 11 hour limit at 4:00 p.m.

Explanation - 30 Minute Break: On Day 1, the driver remained on duty for more than 8 consecutive hours. While remaining on duty for longer than 8 consecutive hours is perfectly legal, the driver may not operate a CMV after being on duty for more than 8 consecutive hours unless a 30 minute break is taken. In the Day 1 example, the driver didn't meet that requirement until being on duty for 9 hours (1 hour beyond the limit), thereby violating the 30 minute break provision from 6:00 p.m. to 7:00 p.m. The driver also failed to take a 30 minute break on Day 2. Since the driver was on duty (driving) for more than 8 hours beginning at 4:00 p.m., all drive time after 4:00 p.m. was in violation of the 30 minute break provision.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 10:00 a.m. on Day 1. The driver reached the 14 hour limit at midnight (the 2 hour sleeper berth period is included in the 14 hour calculation because it is less than 8 hours). The driver then entered the sleeper berth for 8 consecutive hours and took advantage of the split sleeper berth provision. This moves the 14 hour calculation point to 9:00 p.m. on Day 1, the end of the first of the two qualifying breaks. Counting forward from there (and excluding the 8-hour sleeper period), the driver had 11 hours remaining as of 8:00 a.m. on Day 2. Those 11 hours were used up by 7:00 pm

Which log below contains at least one violation?

Day 1

Day 2

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

Every time you pull off the expressway to take a break, you use about how much time off your 11-hour driving limit?
  • About 5 minutes
  • About 10 minutes
  • About 1 minute
  • About 30 minutes

Quote From Page 0 Of The Illinois CDL Manual:

Bonus Tip: Stay Away From Caffeine!

Alright, well, you don't have to completely stay away from caffeine. Everyone needs a pick-me-up now and then. But remember, every time you stop, you are using up about 10 minutes from your log. By taking in a lot of caffeine, you'll certainly have to stop more frequently. You should try to limit your caffeine intake and as long as you're being safe and healthy, limit the amount of any fluids you're drinking. This may seem like a ridiculous tip, but drivers who "think outside the box" are generally rewarded with higher earnings. Remember, every minute counts!

What happens if you spend 8 hours in the sleeper berth?
  • 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
  • You will regain 8 hours on your 14 hour on duty time
  • 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
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.

Which statement is true?
  • None of these statements are true
  • If you are doing work for your motor carrier but aren't being paid for the work, you may log it as off duty time
  • Washing your truck may be logged as off duty time
  • All time taking care of your truck when it is broken down may be logged as off duty time
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 responsibility for performing work and be free to pursue activities of your own choosing.

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.

Is the below example a completed 34 hour restart?

Day 1

Day 2

  • None of these answers are correct
  • No, the driver didn't spend enough time off duty to complete the restart
  • 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.
This is a question from page 105 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1





Day 2






Explanation - 34 Hour Restart: This example shows a 34 hour restart which is incomplete. While the driver took a total of 34 hours off duty from 4:00 a.m. on Day 1 until 4:00 p.m. on Day 2 (total of 36 hours off duty) the driver still did not meet the requirements. Two rest periods must be taken between the hours of 1:00 a.m. to 5:00 a.m. and in this example, only one rest period during those hours were completed (Day 2). This driver is not necessarily in violation of any rules, but he/she still must count back the previous 8 days when calculating the 70 hour limit as the 34 hour break did not reset the 70 hour limit.

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