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.

From The 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.

TruckingTruth's Advice:

During the rest of this program, we will be referencing HOS instead of saying Hours of Service every time. As an industry standard, HOS always stands for Hours of Service and the vast majority of people in the trucking industry are very familiar with the term HOS.

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!?

Carriers:

In addition to law enforcement and DOT officials, most carriers have their own company policies regarding logbooks. Not only do carriers want to ensure their drivers are being safe on the roadways, but carriers often receive audits from DOT officials and can be heavily fined if too many drivers have violations on their logs. 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 can be checked virtually anytime. Never press your luck. Make sure your logbook is legal and up to date all the time.

There are three maximum limits you must follow at all times. Those limits are:
  • The 16 hour on duty limit, the 10 hour driving limit, and the 50/60 hour on duty limit
  • None of these answers are correct
  • The 11 hour on duty limit, the 14 hour driving limit, and the 70/80 hour duty limit
  • The 14 hour on duty limit, the 11 hour driving limit, and the 60/70 hour on duty limit

From The 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.

What does the 14 hour on duty limit mean?
  • From the time you first go on duty after a 10 consecutive hour break, you are allowed 14 consecutive hours to use your 11 hour drive time
  • You are allowed to drive for 7 hours then must take a 7 hour break
  • You can drive up to 14 consecutive hours per day
  • You must rest for at least 14 consecutive hours each day
Click here to look up the answer

From The CDL Manual

The 14 Hour 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 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 work (performing vehicle maintenance, loading / unloading cargo, fueling, 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 duty period even if you take some off duty time, such as a lunch break or a nap, during those 14 hours.

Example: You have had 10 continuous hours off and you begin working at 6:00 a.m. (vehicle inspection, fueling, loading / unloading freight, etc.). You must not drive your truck after 8:00 p.m. that evening. You may do other work after 8:00 p.m.(load / unload freight, perform maintenance duties, etc.), but you cannot do any more driving until you have taken another 10 consecutive hours off.

TruckingTruth's Advice:

The 14 hour rule quite simply means that as soon as you begin working for the day, regardless of what time it is, you have 14hrs to complete your day. Once your 14 hours are up, you may not drive again until you have had a minimum of 10 consecutive hours off duty, at which point, your 14 hour clock will reset.

Which statement below accurately describes the 11 hour driving limit?
  • You can only drive between the hours of 9am to 8pm each 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 may not perform any on duty work (driving or non-driving duties) after 11 consecutive hours have passed since you began your work day

From The 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.

What is the 8 day / 70 hour on duty limit?
  • You must have taken at least 70 hours off during the previous 8 days in order to drive legally
  • You are not allowed to be on duty more than 70 hours within the previous 8 days
  • None of these answers are correct
  • You are not allowed to drive after you've been on duty 70 hours in the previous 8 consecutive days
Click here to look up the answer

From The CDL Manual

The 8 day / 70 hour limit:

If your company does operate vehicles every day of the week, your employer may assign you to the 70-hour/8-day schedule. This means that you are not allowed to drive after you've been on duty 70 hours in any 8 consecutive days. Once you reach the 70 hour limit, you will not be able to drive again until you have dropped below 70 hours for an 8 consecutive day period. You may do other work, but you cannot do any more driving until you get below the limit. Any other hours you work, whether they are for a motor carrier or someone else, must be added to the total.

TruckingTruth's Advice:

The 8 day / 70hr limit will restrict how much time you're allowed to be on duty during an 8 day period. So if you take a 10 hour break to reset your 11 and 14 hour clocks, but have been on duty / driving for 65 hours in an 8 day period, you will only be able to drive 5 hours.


We'll give you some more examples later on in the program. This can be a little difficult to understand, but try to understand the differences between the 11hr, 14hr, and 70hr clocks.

What is a 34 hour restart?
  • The regulations allow you to "restart" your 60 or 70 hour clock calculations after having at least 34 consecutive hours off duty
  • If you take at least two 17 hour breaks within an 8 day period, all your hours will reset
  • After you have been on duty for 34 hours, you must take a 70 hour break
  • If you drive less than 34 hours in 7 days, all your hours will reset
Click here to look up the answer

From The CDL Manual

The 34 Hour Restart

The regulations allow you to "restart" your 60 or 70 hour clock calculations after having at least 34 consecutive hours off duty. In other words, after you have taken at least 34 hours off duty in a row, you have the full 60 or 70 hours available again. You would then begin counting hours on the day of the restart and not go back the full 7 or 8 days.

TruckingTruth's Advice:

If you are planning to become an OTR truck driver, you will use the 8 day / 70 hour limit. That means, you are unable to drive once you've been on duty for more than 70 hours within an 8 day period. If you've worked close to that limit, you may want to "reset" the 70 hour limit. The only way to completely reset your 70 hour limit is to take an extended amount of time off duty. If you take 34 consecutive hours off without driving or performing on duty tasks, your 70 hour limit will reset.

Is the following example within legal HOS limits?

- A trucker starts driving at 12:00pm

- At 5pm the driver takes a 1 hour break

- At 6pm the driver begins driving again

- At 11:30pm, the driver shuts down and goes off duty for 10 consecutive hours

  • No, the driver did not satisfy the 30 minute break requirement
  • No, the driver exceeded his 14 hour on duty time
  • No, the driver exceeded his legal drive time by 30 minutes
  • Yes, the example is legal
Click here to look up the answer

From The CDL Manual

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.

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 on duty tasks but you cannot drive.

TruckingTruth's Advice:

Let's go through the example together:

Beginning the day:

In this hypothetical situation, a driver begins his day at 12pm. At that point, both his 14 hour on duty clock and 11 hour driving clock have started.

Taking a break

When the driver takes his 1 hour break, his 11hr clock stops. At this point, since he is no longer driving, only his 14 hour clock continues to run. This break also satisfies the 30 minute break provision. So far, here's how his time looks:

  • 14 hour clock: 9 hours remaining (will be 8 hours remaining once his break is complete).
  • 11 hour clock: 6 hours remaining (will remain 6 hours throughout his entire break).
Resume driving:

So, after the driver takes his 1 hour break, he still has 9 hours on his 14 hour on duty clock and 6 hours on his 11 hour driving clock remaining. Since he took 1 hour off duty, he now has 8 more consecutive hours that he can drive without taking a 30 minute break off duty.

Shutting down:

It has now been 5.5 hours since the driver took his break. So let's look at our remaining hours again.

  • 14 hour clock: The driver had 8 hours remaining once he started driving again after his break and 5.5 hours have passed since then. The driver still has 2.5 hours remaining on his 14 hour on duty limit.
  • 11 hour clock: The driver had 6 hours remaining after his break. He has driven an additional 5.5 hours since then. That means the driver still has 30 minutes remaining on his 11 hour driving clock.

So yes, this driver is indeed legal! And once he takes 10 consecutive hours off, he can do it all over again.
