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.

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
  • You might be able to sneak in a 34 hour restart
  • All of these are reasons to arrive at your destination as quickly as possible

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.

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
  • Time spent doing paid work for anyone who is not a motor carrier
  • Anytime you aren't driving
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.

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

Which day below contains at least 1 violation?

Day 1

Day 2

  • Day 1 contains at least 1 violation
  • Day 2 contains at least 1 violation
  • Both days contain violations
  • 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.

A 30 minute break violation occurs on the below example. What day and time does the violation occur?

Day 1

Day 2

  • Day 2 at 3:00 p.m.
  • Day 2 at 2:00 p.m.
  • Day 1 at 6:00 p.m.
  • Day 2 at 3:00 a.m.
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 from 6:00 p.m. to 7:00 p.m. on Day 1.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the driver was eligible to drive for up to 11 hours beginning at 10:00 a.m. on Day 1, but only drove 9 hours before entering the sleeper berth. With only 8 hours in the sleeper berth, the calculation point does not change, so the driver had 2 hours remaining to drive at 3:00 a.m. on Day 2. After reaching the 11 hour limit at 5:00 a.m. on Day 2, the driver went off duty for at least 2 consecutive hours, making him or her eligible for the split sleeper berth provision. In other words, the driver accumulated at least 10 hours of rest using a combination of at least 8 consecutive hours in the sleeper berth (7:00 p.m. on Day 1 to 3:00 a.m. on Day 2) and another off duty break of at least 2 consecutive hours (5:00 a.m. to 7:00 a.m. on Day 2). This moves the calculation point to the end of the first of the two periods of rest, or 3:00 a.m. With 2 hours spent driving after 3:00 a.m., the driver had 9 remaining hours by 7:00 a.m. and used only 8 additional hours.

Explanation - 30 Minute Break: The driver was required to take at least 30 consecutive minutes off duty by 6:00 p.m. on Day 1 before continuing to drive. Since the driver did not complete this requirement until an hour later, the driver was in violation from 6:00 p.m. until 7:00 p.m. on Day 1. On Day 2 the driver was on duty longer than 8 consecutive hours. This is perfectly legal. The rules only state that a driver may not drive after being on duty longer than 8 consecutive hours without first taking a 30 consecutive minute break. So remaining on duty without a break beyond 8 hours is legal unless any driving takes place. Since no driving took place after 3:00 p.m. on Day 2, no violation occurred on that day.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 10:00 a.m. on Day 1. By 7:00 p.m. on Day 1, the driver had 5 hours remaining (but only 2 hours of driving available). At 3:00 a.m. on Day 2, the driver still had 5 hours remaining, because any sleeper berth period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation. By 7:00 a.m. on Day 2, the driver had taken 8 consecutive hours in a sleeper berth plus another 2 consecutive hours off duty, making him or her eligible to use the split sleeper berth provision. This moves the 14 hour calculation point to 3:00 a.m. Therefore, at 7:00 a.m. on Day 2, the driver had 10 hours of time remaining (14 hour limit - 2 hours driving - 2 hours off duty = 10 total hours remaining) and used only 9 hours before the end of Day 2.

Which violation occurs on the below example?

  • There is a 30 minute break violation
  • There is a 14 hour rule violation
  • There are no violations on this log
  • There is an 11 hour rule 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 is a 14 hour rule violation from 9:00 p.m. - 10:00 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 2:00 a.m. The driver drove for just 1 hour between 9:00 p.m. and 10:00 p.m., far below the 11 hour driving limit.

Explanation - 30 Minute Break: The driver never drove a CMV after being on duty for more than 8 hours. Therefore, no violation has occurred.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available beginning at 2:00 a.m. Because the 14 hour calculation includes all off duty time of less than 10 consecutive hours, all of this driver's time between 2:00 a.m. and 10:00 p.m. is included in the calculation. Even though the driver spent 9 consecutive hours off duty, the 14 hour limit does not get extended. In order for an 8 consecutive hour (or longer) break to extend the 14 hour limit, the 8 consecutive hours must occur in the sleeper berth. However, the driver could have spent 10 hours off duty and both the 11 and 14 hour limits would have reset. The driver reached the 14 hour limit at 4:00 p.m. and violated the 14 hour rule at 9:00 p.m. by driving a CMV beyond the 14 hour duty limit.

NOTE: Even though this driver had 10 hours off duty during the day and only drove for 1 hour, that hour of driving was done in violation of the 14 hour rule. The driver did not obtain another 10 consecutive hours off duty, so the calculation point does not change and the 9-hour break must be included in the calculation of the 14 hour limit. After 10:00 p.m., the driver must be off duty for at least 10 consecutive hours, or in a sleeper berth for at least 8 consecutive hours, before driving again.

To remain in compliance: The driver should not have driven after 4:00 p.m., which was the end of the 14 hour limit. If he or she had gone into a sleeper berth for the 9 hour break, that break would have been excluded from the 14 hour calculation and the driver would have remained in compliance. Furthermore, the driver could have elected to remain off duty until 10:00 p.m. for a total of 10 hours off duty which would have reset both the 11 hour and 14 hour limits.
