Quote From Page 0 Of The Illinois CDL Manual:

HOS regulations determine when and how long you are allowed to drive a commercial motor vehicle (CMV). This is accomplished by placing specific limits on the number of hours you can drive or be considered on duty. The rules also specify how much time you must remain off duty before you can legally resume any driving duties. And finally, the regulations dictate when breaks are required during your workday.

HOS regulations determine when and how long you are allowed to drive a commercial motor vehicle (CMV). This is accomplished by placing specific limits on the number of hours you can drive or be considered on duty. The rules also specify how much time you must remain off duty before you can legally resume any driving duties. And finally, the regulations dictate when breaks are required during your workday.

There are three limits and one break requirement which must be followed at all times. They are:

  • The 14 hour on duty limit.
  • The 11 hour driving limit.
  • The 30 minute break.
  • The 60/70 hour on duty limit.

TruckingTruth's Advice:

Make sure you are familiar with the different rules you must abide by. The 11, 14, 60/70 hour clocks and the 30 minute break are very basic rules you'll need to follow everyday. If you do not understand them, you will struggle through the rest of this program. If you have a question, head on over to our forum or contact one of us by using the "About Us" tab above.

EOBR's are required to automatically record which of the following?
  • All of these answers are correct
  • Road speed
  • Miles driven
  • Engine use
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.

Why should you always plan on arriving to your destination as quickly as possible?
  • Many things can go wrong along the way
  • Many customers will give you an earlier appointment time if you show up early, even if they said they wouldn't over the phone
  • 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.

At what time does a violation occur on this log?

  • 9:00 p.m.
  • 8:00 p.m.
  • 7:00 p.m.
  • 10:00 p.m.
This is a question from page 104 - 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 10:00 p.m. - 11:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 hours of driving time available starting at midnight. The driver completed 9 hours of driving by 11:00 p.m. and went off duty, so there are no violations of the 11 hour rule.

Explanation - 30 Minute Break: Since the driver was never on duty longer than 8 consecutive hours, the 30 minute break provision was never a factor.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at midnight. The driver used 10 of those hours by 10:00 a.m. before entering the sleeper berth for 8 consecutive hours. The 8 consecutive hour sleeper berth period is excluded from the 14 hour limit, but the 1 hour off duty period connected to that sleeper berth period is not. So the 14 hour limit was reached at 10:00 p.m., 4 hours after the end of the sleeper berth period, and the driver violated the rule by continuing to drive for another hour. To remain in compliance, the driver should have either stopped driving at 10:00 p.m., or remained in the sleeper berth from 6:00 p.m. - 7:00 p.m.

On which of the below logs did a violation occur?

Day 1

Day 2

  • Both days contain at least one violation
  • Day 1 contains at least one violation
  • Day 2 contains at least one violation
  • No violations occurred on either day
This is a question from page 98 - 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 in this example.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver had 11 available hours of driving and began driving at 11:00 a.m. on Day 1. The driver drove between the hours of 11:00 a.m. until 4:00 p.m. (5 hours), went off duty for 1 hour, then drove between 5:00 p.m. and 11:00 p.m. (6 hours). No more driving was completed on Day 1 so the driver did not exceed the 11 hour driving limit (5 + 6). Starting at Midnight going into Day 2, the driver may not drive a CMV until he/she goes off duty for a minimum of 10 consecutive hours, which is indicated on the log. On Day 2, the driver only operated a CMV for 3 hours and so no violation occurred.

Explanation - 30 Minute Break: The 1 hour off duty break between 4:00 p.m. and 5:00 p.m. on Day 1 fulfilled the 30 minute break requirement. While only 30 minutes off duty is required, taking a break longer than 30 minutes (as in this case) is perfectly legal. The driver may drive a CMV only if 8 hours or less have passed since the end of the driver’s last off duty period of at least 30 minutes. On Day 2, the driver was only on duty for a 3 hour stretch which wouldn't require the 30 minute break. Both Day 1 and Day 2 of this example are free from any 30 minute break violations.

Explanation - 14 Hour Limit: After taking 10 consecutive hours off duty, the driver changed to on duty status at 10:00 a.m. on Day 1. This is the calculation point for the 14 hour limit so the driver has until Midnight to complete all driving tasks. At midnight, the driver switched to the sleeper berth for 10 consecutive hours. Since the driver performed all driving tasks within 14 hours on Day 1, no violation occurred. No violation occurred on Day 2, either, since the driver was only on duty (driving) for a total of 3 hours.

How many violations occur on the below example?

Day 1

Day 2

  • 1
  • 0
  • 3
  • 2
This is a question from page 100 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: Day 2 contains 2 violations. There is a 14 hour rule violation from 8:00 a.m. - 10:00 a.m. and a 30 minute break violation from 8:00 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. The driver completed 11 hours of driving by 10:00 a.m. on Day 2 and was not eligible for more driving until taking time off duty. Because the driver had 8 consecutive hours in a sleeper berth and then 2 consecutive hours off duty, he or she was eligible for the split sleeper berth provision, meaning, 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. This moves the 11 hour calculation point to the end of the first of the two qualifying breaks, or 8:00 a.m. on Day 2. Counting forward from there, the driver had 2 hours of driving plus an additional 9 hours of driving for a total of 11, with no violations.

Explanation - 30 Minute Break: On Day 1, the driver was never on duty long enough to require a 30 minute break. But on Day 2, once the driver went on duty (driving) at noon, he/she had to complete a 30 minute break by 8:00 p.m. before driving any further. The driver continued to drive beyond that limit by one hour. From 8:00 p.m. to 9:00 p.m. the driver 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 (note that all off duty periods of less than 10 hours are included in the calculation). The driver then entered the sleeper berth for 8 consecutive hours, which is excluded from the 14 hour calculation. But because the driver did not have an earlier 2 hour break and did not obtain 10 consecutive hours off duty, the calculation point does not move (that is, the 14 hour calculation continues from Day 1 into Day 2). At 8:00 a.m. on Day 2, the driver was still at the 14 hour limit and had no time remaining. He or she violated the rule by driving for 2 more hours. The driver then took 2 consecutive hours off duty and was able to take advantage of the split sleeper berth provision. The calculation point moves to 8:00 a.m. on Day 2 (the end of the first period used in the “split”), and counting forward from there the driver accumulated just 13 hours by 9:00 p.m., within the limits.

Which of the following is considered off duty time?
  • When you are relieved of all duty and responsibility for performing work
  • Time inspecting or servicing your truck
  • Anytime you aren't driving
  • 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.

Is there a 14 hour rule violation on Day 2?

Day 1

Day 2

  • Yes, at 1:00 a.m.
  • No 14 hour rule violation occurs
  • Yes, at 9:00 p.m.
  • Yes, at 7:00 a.m.
This is a question from page 100 - 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 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.
