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.

Which statement below accurately describes the 11 hour driving limit?
  • 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
  • You can only drive between the hours of 9am to 8pm each day
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.

If you have used up all of your 14 hour on duty time, how many hours would you regain after an 8 hour break in the sleeper berth?
  • You will still have no hours remaining
  • None of these answers are correct
  • You would regain half of your hours (7 hours total)
  • Your 14 hour limit would reset
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:

An 8 hour break will never add more hours to any of your limits. Rather, an 8 hour break simply extends your time by not counting the break against your 14 hour duty clock. The concept is confusing, but it's actually very simple. Here are some examples.

  • If you have 5 hours remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 5 hours remaining.
  • If you have 1 hour remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 1 hour remaining.
  • If you have 0 hours remaining on your 14 hour duty clock then go into the sleeper berth for 8 hours, at the end of your break you will still have 0 hours remaining.
  • As you can see, you will not gain any hours back after taking an 8 hour break. Instead, your available hours have simply been extended.

    So why would you ever want to take an 8 hour break instead of a 10 hour break? Here's an example:

    Let's say you have a delivery in the morning, but you are not allowed to park at your delivery location overnight. Instead, you have to stop at a truck stop 20 miles away to park for the night. In order to make your appointment on time, you must leave after only resting for 8 hours. If that's the case, you can still make the delivery on time by taking an 8 hour break instead of a full 10 hour break.

    Little situations like this will come up frequently as a truck driver. That's why it's so important to understand these little loopholes and tricks. We'll go through more examples later on in this section, but try to have a full understanding of the 10, 8 and split sleeper rules.

What violation occurs at 2:00 p.m. on this example?

  • No violation occurs at 2:00 p.m.
  • 11 hour rule violation
  • 30 minute break violation
  • 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:

Violations: There is a 14 hour rule violation from 2:00 p.m. - 3:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver was eligible to drive for up to 11 hours beginning at midnight. The driver reached the 11 hour limit at 3:00 p.m., at which point he or she entered the sleeper berth for 8 consecutive hours. The 8 hour sleeper berth period, combined with the earlier 2 hour off duty period (in this case, a combination of sleeper berth and off duty time beginning at 9:00 a.m.), made the driver eligible for the split sleeper berth provision. That is, 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 either off duty and/or in a sleeper berth. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 11:00 a.m. After 11:00 a.m., the driver accumulated 4 hours of driving time, leaving 7 hours to be used after 11:00 p.m.

Explanation - 30 Minute Break: Since the driver was never on duty beyond an 8 consecutive hour period without at least 30 minutes taken off duty, there are no violations of the 30 minute break provision in this example.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at midnight. The 14 hour limit was reached at 2:00 p.m., but the driver continued to drive, resulting in a 1 hour violation from 2:00 p.m. to 3:00 p.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 11:00 a.m. Counting forward from there (and excluding the 8 hour sleeper berth period), the driver had 10 hours remaining at 11:00 p.m. and had no further violations. The fact that the driver returned to compliance after 11:00 p.m. does not remove the violation from 2:00 p.m. - 3:00 p.m. The driver should have taken the break at 2:00 p.m. to avoid the violation.

Who enforces HOS regulations?
  • Police Officers
  • Carriers
  • DOT Officials
  • All of these answers are correct
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. 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 has forced carriers to crack down on HOS violations even more.

TruckingTruth's Advice:

You should always be prepared for a random inspection. Your logs must always be current. If you get pulled into a weigh station or get pulled over for a random inspection, which does happen, and your logbook is not current, you will be cited for a violation.

The carrier you work for will also have logbook auditors. Companies themselves are required to keep driver logs for a period of time and receive random audits from the DOT. If too many of their drivers have logbook violations, the company can be fined or otherwise penalized. They have an interest in passing those audits so if you cause too many problems for them, they will take action.

Which of these could be considered off duty time?
  • Fueling your truck
  • Washing your truck
  • Taking a 2 hour nap at a rest area
  • Completing paperwork required by your carrier

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

TruckingTruth's Advice:

Once you start your day, you have 14 hours to complete it until you're not allowed to drive anymore. While you may go off duty during that 14 hour period, it will not change the time at which the 14 hour on duty limit will expire.

Which violations have occurred in the below example?

Day 1

Day 2

  • There is an 11 hour violation only
  • There is a 14 hour violation and a 30 minute break violation
  • There is a 14 hour violation only
  • There is a 14 hour violation and an 11 hour 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 is an 11 hour rule violation from 11:00 a.m. - 1:00 p.m., and a 14 hour rule violation from 7:00 a.m. - 1:00 p.m., both on Day 2.

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. The driver did not have another 10 hour break (or the equivalent) until 1:00 p.m. on Day 2, so the calculation point never changes. The driver accumulated 7 total hours of driving on Day 1 and reached the 11 hour limit at 11:00 a.m. on Day 2. The violation began when the driver continued driving after that limit.

Explanation - 30 Minute Break: Since the longest consecutive stretch of on duty time was only 6 hours, the driver was never required to take a 30 minute break on either Day 1 or Day 2.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit starts at 10:00 a.m. on Day 1. The 14 hour limit was reached at midnight, and the driver violated the 14 hour rule by driving a CMV starting at 7:00 a.m. on Day 2.

To remain in compliance: The driver should have stayed in the sleeper berth for one additional hour during one of the two sleeper berth breaks. This would have given the driver the equivalent of 10 hours off duty, making him or her eligible for the sleeper berth provision. This would have moved the calculation point to the end of the first of the two breaks (10:00 p.m. on Day 1) and the driver would have remained in compliance on Day 2, in this example.

Which statement below is false?
  • The current day's log must be current to your last change of duty status
  • Authorized government inspectors may check your logs at any time
  • You must have a log for each day of the last 8 days
  • You never need to log your days off
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.
