Which statement below is true?
  • An EOBR may be used without creating any paper copies
  • EOBRs must be capable of printing a log sheet
  • EOBRs must store at least the previous 3 days of log information
  • EOBRs are declining in usage
This is a question from page 106 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The EOBR device must be capable of displaying or printing for enforcement officers the times of duty status changes and other required information. It must also store this information for the prior 7 days. An EOBR may be used without creating any paper copies of logs by transmitting the data electronically to the carrier, or it may be used to print copies of the logs that would be signed by the driver and mailed to the carrier.

What Is The Future Of EOBRs

Even 5 years ago, the vast majority of major trucking carriers relied on paper logs. But the DOT and FMCSA have begun a historic crackdown on enforcing and regulating, among other things, HOS rules. Violations now effect both the drivers record as well as the carriers safety rating. We are at a turning point where it now makes financial sense for trucking companies to switch over from using paper logs to EOBRs. These electronic recording devices are here to stay and will only grow in usage as time goes on. In fact, on January 31, 2011, the FMCSA proposed a rule that would require Electronic On-Board Recorders for interstate commercial truck and bus companies.

What violations occurred on Day 2 of this example?

Day 1

Day 2


  • There is a 14 hour rule violation and a 30 minute break violation
  • There is an 11 hour rule violation and a 30 minute break violation
  • There is a 14 and 11 hour rule violation as well as a 30 minute break violation
  • There is a 14 and 11 hour rule violation
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 are a total of 3 violations on Day 2. First, there is a 14 hour rule violation from 1:00 a.m. - 2:00 a.m. Second, there is a 30 minute break violation from 8:00 p.m - midnight. And third, there is also an 11 hour rule violation from 11:00 p.m. - midnight.

Explanation - 11 Hour Limit: After 10 consecutive hours off duty using a combination of off duty and sleeper berth time, the driver was eligible to drive for up to 11 hours starting at 10:00 a.m. on Day 1. By 2:00 a.m. on Day 2, the driver had driven 9 hours. By obtaining 10 consecutive hours off duty on Day 2, the 11 hour calculation point moved to noon on Day 2, at which point the driver had 11 hours of driving time available again. The driver violated the 11 hour rule by driving beyond the 11 hour limit between 11:00 p.m. and Midnight.

Explanation - 30 Minute Break: On Day 1, the driver was never required to take a 30 minute break because the longest stretch of on duty time during the entire day was only 6 consecutive hours. On day 2, the driver never took a minimum of 30 consecutive minutes off duty, even after remaining in the driver's seat for more than 8-hours. At 8:00 p.m. the driver was in violation of the 30 minute break provision and remained in violation for the remainder of the 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. The driver reached the 14 hour limit at midnight (the 5-hour sleeper-berth period is included in the 14 hour calculation because it was less than 8 hours). Though the driver was not eligible to drive a CMV after midnight, he or she was able to continue working on duty without violation, as long as no driving took place (which was done for 1 hour). The driver violated the 14 hour rule by driving a CMV at 1:00 a.m. Then, after 10 consecutive hours off duty, the 14 hour calculation point moved to noon on Day 2, at which point the driver had 14 hours available to work again.

Which day below contains a 30 minute break violation?

Day 1

Day 2

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

Which statement below is false?
  • Non-DOT law enforcement officers need probable cause to inspect your logbook
  • Your logbook can be randomly checked anytime you go through a weigh station
  • The increased use of electronic logging devices has forced carriers to crack down on HOS violations
  • Your logbook can be checked by your carrier at anytime
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 (discussed later) has forced carriers to crack down on HOS violations even more.

TruckingTruth's Advice:

Your logbook could be checked at anytime for any reason. Make sure it is always updated!

After taking 10 consecutive hours off duty, a driver begins to work at 8:00 a.m. The driver may operate a commercial motor vehicle until what time?

  • 6:00 p.m.
  • 10:00 p.m.
  • 8:00 p.m.
  • Midnight
This is a question from page 93 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The 14 Hour On Duty Limit

This limit is usually thought of as a "daily" limit, even though it is not based on a 24 hour period. You are allowed a period of 14 consecutive hours of on duty time after being off duty for 10 or more consecutive hours. The 14 consecutive hour duty period begins when you start any kind of reportable work (performing vehicle maintenance, loading / unloading cargo, fueling, driving, etc.). Once you have reached the end of this 14 consecutive hour period, you cannot drive again until you have been off duty for another 10 consecutive hours.

Your driving is limited to the 14 consecutive hour on duty period even if you take some off duty time, such as a lunch break or a nap, during those 14 hours.

TruckingTruth's Advice:

While you are only allowed 11 hours of driving after taking a 10 consecutive hour break, you are able to complete those 11 hours at any point during the 14 hour limit.

There will be times when you must take a minimum of a 30 minute break off duty before performing which of the following tasks?
  • Doing your required daily trip inspection
  • Fueling a CMV
  • Loading or unloading freight
  • Driving a CMV
This is a question from page 93 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

30 Minute Break Provision

There are times when you will be required to take a 30 minute break. If you have been on duty for more than 8 consecutive hours without at least 30 minutes off duty, you are not allowed to operate a CMV until a 30 minute break is taken. You may perform other on duty tasks but you cannot drive.

TruckingTruth's Advice:

Your 30 consecutive minute off duty break can be taken either off duty or in the sleeper berth. You may perform any and all on duty tasks without taking a 30 minute break except for any driving tasks. If you have been on duty (driving or not) for 8 hours without taking at least 30 consecutive minutes off duty, you must take the 30 minute break before performing any CMV driving tasks.

How current must your logbook be?
  • It must show your last duty change
  • Your current day log must be filled out within' 48 hours
  • You must show what time you went on duty, then the rest of the log can be filled out when you go off duty for the day
  • Logs must be filled out at the end of each driving day
This is a question from page 96 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

The current days log must be current to your last change of duty status.

TruckingTruth's Advice:

Quite a few truck drivers are written citations or are placed out of service because their logbooks aren't current. These citations are the result of laziness. You must be current to your last duty status change. So if you are randomly stopped by a police officer and your logbook is checked, it should when you last changed into the driving status.

What violations occurred in this example?

Day 1

Day 2

  • There is a 14 hour rule violation
  • There are no violations
  • There is a 14 hour rule violation as well as a 30 minute break violation
  • There is a 30 minute break violation
This is a question from page 103 - click here to look up the answer

Quote From Page 0 Of The Illinois CDL Manual:

Day 1

Day 2

Violations: There is a 14 hour rule violation from 5:00 a.m. - 8:00 a.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 at 5:00 a.m. on Day 1. Before obtaining another 10 consecutive hour break (beginning at 9:00 a.m. on Day 2), he or she drove for only 7 hours, well within the limit.

Explanation - 30 Minute Break: All requirements for the 30 minute break provision were met. The driver never drove after being on duty for longer than 8 consecutive hours without at least 30 consecutive minutes spent off duty.

Explanation - 14 Hour Limit: After 10 consecutive hours off duty, the driver had 14 hours available at 5:00 a.m. on Day 1.

The 14 hour calculation includes:
  • All off duty time of less than 10 consecutive hours;
  • All sleeper-berth time of less than 8 hours; and
  • All on duty and driving time.

Therefore, the driver reached the 14 hour limit at 7:00 p.m. on Day 1, and the violation began when the driver drove a CMV at 5:00 a.m. on Day 2.

NOTE: Although this driver had 15½ hours off duty between 9:00 a.m. on Day 1 and 1:00 a.m. on Day 2, that off duty time was interrupted by a period of 30 minutes on duty (3:00 p.m. on Day 1). Therefore, both the 6-hour sleeper-berth period and the 9½-hour off duty period are included in the 14 hour calculation (the calculation point does not change from 5:00 a.m. on Day 1). In addition, note that the driver can legally work after reaching the 14 hour limit, but cannot drive a commercial motor vehicle.

To remain in compliance, the driver should not have gone on duty from 3:00 p.m. - 3:30 p.m. on Day 1, or should have remained off duty from 1:00 a.m. - 1:30 a.m. on Day 2, in order to get 10 consecutive hours of off duty time.
