You need to study the Logbook section of our High Road Training Program.

CDL:

Commercial Driver's License (CDL)

A CDL is required to drive any of the following vehicles:

  • Any combination of vehicles with a gross combined weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
  • Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing another not in excess of 10,000 pounds.
  • Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
  • Any vehicle required by federal regulations to be placarded while transporting hazardous materials.

Logbook:

A written or electronic record of a driver's duty status which must be maintained at all times. The driver records the amount of time spent driving, on-duty not driving, in the sleeper berth, or off duty. The enforcement of the Hours Of Service Rules (HOS) are based upon the entries put in a driver's logbook.

Here are the basics

In 8 days you can only be On Duty or Driving for a total of 70 hours. You cannot drive after you reach this number of hours worked. In a day you cannot drive after reaching 14 consecutive hours of working. You cannot drive after you have been driving for 11 hours within the 14 hours above. Even if you do not reach 14 hours of work, you still cannot drive after reaching 11 hours of driving time. The 10 hours is the rest period that you need to take before you can start driving again. With the exception of a split sleeper birth and that is what I assume you mean by 8 hour rule. I don't ever do the split sleeper so I have not read up on it.

The 10 hour break/off duty/sleeper basically resets your 14 and 11 hour clocks.

The 34 hour break resets them all to 0. This means the 11, 14 and 70 hour clocks.

10 hour break taken consecutively resets your 11 hour driving and 14 hour on duty time. Must take at least 30 minute break during 8 hours driving. The 11 and 14 hour clocks are pretty much time limits of driving if both the 11 or 14 run out, you cant drive until you take a 10 hour break in sleeper berth or off duty. Like Anchorman said, check out the High Road CDL training program for alot more details it is extremely helpful and it'll explain everything.

Sleeper Berth:

The portion of the tractor behind the seats which acts as the "living space" for the driver. It generally contains a bed (or bunk beds), cabinets, lights, temperature control knobs, and 12 volt plugs for power.

8 hours in a sleep will extend your 14 hr clock. For example you have 5 hours of drive time left but your Appt is 9 hours from now and just down the street. You can go 8 in sleeper and will still have the 5 hours. You do not have to do a 8/2 split for this to work. I sometimes take the 8 in sleeper to extend my clock... run out my remaining drive time then do 10 hr break.

In an 8/2 split.... you can then drive after the 8 in sleeper. Say out of the 5 hours available you drive 2 hours. You now go off duty or sleeper for 2 houts. Because you got 10 hrs in a break with an 8/2 split... you are reset .... however your 14 clock starts at the end of the 8 hour period and then instead of 11 hrs of drive time... you must deduct what you drove between the 8 and 2. So if you drove 2 hours after the 8 in sleeper then took 2 hours off... you would have 11 hours of drive MINUS the 2 hrs you drove in between the two breaks. Which would give you 9 hours of drive time with a 14 hour clock starting at the end of the 8 in sleeper.

Did I explain that the right way and in an understandable way??

Makes sense to me.
