Good Luck!

As a way to maximize all time available, you should always do the following:

  • Know where you will fuel before you begin your trip
  • All of these answers are correct
  • Plan ahead for unexpected delays
  • Know where your breaks will be taken along your routing

Plan Your Trip

While proper trip planning has always been important, it's even more important while driving with an EOBR. Let's face it, drivers weren't exactly honest driving with paper logs. If they didn't plan a trip correctly and couldn't make their pickup or delivery on time, the problem could be easily resolved by lying on the logbook. Not only is this practice illegal, but it's nearly impossible to do on electronic logs. Before you accept a load, you should plan out all of the details of your trip including the following:

  • Know where you will fuel.
  • Know where you will take your breaks.
  • Plan your route and be sure you have the correct directions to each location you will be going to.
  • Schedule an ETA for your arrival at your destination.
  • If your trip will take longer than 1 day, plan out each day of your trip.
  • Leave yourself some cushion room in case of a road closure, unexpected traffic, a weather event, etc.
    • If you can make your trip safely and legally but you don't have a comfortable cushion time, inform your dispatcher about the situation before taking the load.

What does DOT stand for?
  • Days of On-Duty Time
  • Department of Timekeeping
  • Diary of Time
  • Department of Transportation
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. In this section we will guide you through the HOS regulations and teach you the best methods of properly recording your hours.

TruckingTruth's Advice:

Everyone in trucking refers to the Department of Transportation as "The DOT." If you don't know this, you'll sound like a rookie. You don't want that, do ya!?

The 14 hour limit can be extended by:
  • None of these answers are correct
  • Spending 8 consecutive hours either in a sleeper berth or off duty
  • Spending 8 consecutive hours in a sleeper berth
  • Spending 8 consecutive hours off duty
This is a question from page 95 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

2. 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:

Remember, in order to extend the 14 hour limit, all 8 hours must be logged as sleeper berth time. You can't spend the 8 hours off duty or switch back and forth between sleeper berth and off duty time.

In most cases, it makes more sense to simply stay in the sleeper berth for 2 more hours (total of 10 consecutive hours in the sleeper berth). That way, instead of extending the 14 hour limit, you create an entirely new starting point for the 14 hour limit and will have all 14 hours available again.

Which day below contains a 30 minute break violation?

Day 1

Day 2

  • Day 1 contains at least one 30 minute break violation
  • There are no 30 minute break violations on either day
  • Day 2 contains at least one 30 minute break violation
  • Both days contain at least one 30 minute break violation
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

On what day and time does a 14 hour rule violation occur?

Day 1

Day 2

  • Day 2 at 2:00 a.m.
  • There is no 14 hour rule violation
  • Day 2 at 5:00 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 does EOBR stand for?
  • Electronic Occurrence and Break Recorder
  • Electronic On-Board Recorder
  • Enforcement of Break Rules
  • Electric Orientation and Break Recorder
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Many motor carriers have installed electronic devices in their trucks to help accurately record hours of service information. If such a device meets the requirements of the safety regulations, it is called an Electronic On-Board Recorder (EOBR), and may be used in place of a paper logbook.

TruckingTruth's Advice:

EOBRs are slowly becoming the industry standard. If you are hired on with any large carrier, chances are very high that you will be using an EOBR. Many small companies still use paper logbooks, but EOBRs will soon take over.

Which statement is true?
  • All of these statements are true
  • If you spend 8 consecutive hours in the sleeper berth, you can extend your 14 hour limit
  • When using the split sleeper berth rule, you can take your 10 hour break by splitting 8 hours off in the sleeper berth and taking an additional 2 hours off duty
  • If you spend 10 consecutive hours off duty or in a sleeper berth of your truck, your 11 and 14 hour limits completely restart
This is a question from page 95 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

1. Ten consecutive hours off duty:

You may spend time in your sleeper berth to get some of, or all of, the 10 consecutive hours of off duty time. When getting your 10 consecutive hours of off duty time, what is most important is that you do not go on duty or drive during those 10 hours. At the end of the 10 consecutive hours of combined sleeper and/or off duty time, your 11-hour driving and 14 hour duty-period limits would completely restart.

2. 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.

3. Split sleeper / off duty time:

You may also use the sleeper berth in a different way to get the “equivalent of at least 10 consecutive hours off duty.” To do this, two rest periods are required. You must spend at least one of the two required rest periods in your sleeper berth. The required rest period in the sleeper berth must be at least 8 consecutive hours (but less than 10 consecutive hours). This rest period will not count as part of the 14 hours. The other, separate, rest period must be at least 2 consecutive hours (but less than 10 consecutive hours). This rest period may be spent in the sleeper berth, off duty, or sleeper berth and off duty combined. It will count as part of the 14 hours (unless you spend at least 8 consecutive hours in the sleeper berth). It does not matter which rest period you take first. After you complete your second re­quired rest period, you will have a new point on the clock from which to calculate your hours available. This new “calculation point” will be at the time you completed your first required rest period.

TruckingTruth's Advice:

The Sleeper Berth Provision is extremely important for you to be familiar with. It is one of the most confusing parts about the HOS regulations, yet, if you know the rules it will make your life much easier and help your paycheck at the same time. With more and more companies switching to electronic logbooks, understanding all the ways you can legally drive is critically important.

Which day below contains a violation?

Day 1

Day 2

  • Day 1 contains at least 1 violation
  • Day 2 contains at least 1 violation
  • Both days contain at least 1 violation
  • There are no violations on either day
This is a question from page 103 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Logging Example #23

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. There is also a 14 hour rule violation on Day 2 from 5:00 p.m. - 9:00 p.m.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty, the initial calculation point for this driver's 11 hour driving limit is 10:00 a.m. on Day 1. The driver drove 9 hours that day before taking 8 hours off duty in the sleeper berth, leaving 2 hours of driving time available at 3:00 a.m. on Day 2 (the 8 hour sleeper berth period does not result in extra driving time). The driver used those 2 hours and reached the 11 hour limit at 5:00 a.m. when he or she had to stop driving. Then the driver went off duty for at least 2 consecutive hours (8 hours off duty total) to take advantage of the sleeper berth provision. He or she 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 3:00 a.m. on Day 2. Between 3:00 a.m. and 1:00 p.m. on Day 2, the driver had 2 hours of driving, so at 1:00 p.m. there were 9 hours of driving remaining (11 - 9) and the driver stayed within that limit.

Explanation - 30 Minute Break: On Day 1, the driver had been on duty since 10:00 a.m. and was required to take at least a 30 minute break before driving beyond 6:00 p.m. Therefore, the driver was in violation of the 30 minute break provision from 6:00 p.m. to 7:00 p.m. on Day 1. On Day 2, the driver was on duty for a total of 8 hours between 1:00 p.m. and 9:00 p.m. Since the driver went off duty at 9:00 p.m., exactly 8 consecutive hours after first going on duty (driving), no violation occurred.

Explanation - 14 Hour Limit: Calculation of the 14 hour limit starts at 10:00 a.m. on Day 1, but does not include the 8-hour sleeper-berth period (7:00 p.m. on Day 1 to 3:00 a.m. on Day 2) because any sleeper period of at least 8 but less than 10 consecutive hours is excluded from the 14 hour calculation. So by 5:00 a.m. on Day 2, the driver used 11 hours driving and had 3 hours remaining out of the 14 hours allowed. But at 5:00 a.m., the driver went off duty for at least 2 hours, making him or her eligible for the split sleeper berth provision. This moves the calculation point for the 14 hour limit to the end of the first of the two rest periods used to obtain 10 hours off duty, or 3:00 a.m. on Day 2. consecutive hours after 3:00 a.m. is 5:00 p.m., when this driver should have stopped driving but did not.

NOTE: Any period of off duty time less than 10 hours (such as this driver's 8 hour off duty break on Day 2) is included in the 14 hour calculation. Also note that the driver's 8 hour sleeper berth period allowed him or her to drive during the 18th and 19th hour after first coming on duty, but it did not by itself give the driver additional driving time beyond 11 hours.

To remain in compliance, the driver should have stopped driving at 5:00 p.m. on Day 2. The driver would have remained in compliance if he or she had gone off duty for 10 hours on Day 2 instead of just 8, or if he or she had spent those 8 hours in a sleeper berth.
