Can someone explain the 8/2 split to me please!!!! I have never used it but may be in a position tomorrow where it may come in handy. Unfortunately my cdl school did very little log book time and my trainer never explained the split either and I don't want to mess it up. I looked around on here but am still not 100% sure I understand. Any help will be greatly appreciated.

Hi. I use these all the time.

1). You can use 8 hrs in the sleeper to pause your 14 clock. So say you have 5 hours of drive time at noon and do 8 in sleeper. At 2000 you will have 5 hours of drive time. You MUST be in sleeper not off duty for this. And it can be more than 8 hrs but not less. This is true whether you take an additional two hours or not.

2). If you come out of the 8 sleeper with 5 hours on your clock then do at least 2 hours of off duty or sleeper, you the. Reset your clock....but not a full 11/14. The clock starts at the end of the FIRST break. So in the above case, at 2000 you drive four of the five available hours, then take the off duty 2 hrs. Your "new clock" started at 2000. So between the two breaks you drove four hours, therefore once you take the two hour break you would have 7 of drive time (11 drive hours - the time between the two breaks in this case is 11 - 4 = 7). Because your 14 begins at 2000, it would end at 1000.

3). You can take either break first, the rules are basically the same except: if you take the 8 sleeper first, the 2 hour break is included in the 14 clock. It does not pause it. If you take the 2 hours first, the 8 sleeper pauses the 14 clock. So to figure out the 14 clock, you would subtract the drive time between breaks and any on duty time for fueling/ inspection. From 14.

I suggest you try it when it doesn't matter to truly understand it. On a day when you spend two hours at a customer. Drive for a bit then when you can take the 8 sleeper.

Rainy pretty much nailed it. I am not overly fond of it personally, but it can be a very useful tool. Remember the 2 hr does not pause your 14 hr clock the 8hr sleeper resets your 14 hr to the time you entered the sleeper only after 8 hrs of sleeper has been used. As Rainy stated the 2hr break can either be off duty or sleeper berth. I usually do my 2hr as off duty. The 8/2 (2/8) split pretty much effectively extends your day. If you take either too early or too late you don't get much practical use from either. You can do rolling 8/2/8 (2/8/2) just alternate back and forth. I imagine your concept of what day it is will quickly become Swiss cheese though.

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.

It's not something I want to use regularly. Tomorrow the way my drop time and shipper times fall if I do a full 10 I will end up later to next shipper but if I just do 8 at consignee then I will make it to next shipper on time and I figure after my pick up I will only go as far as I need to to find a place to shut down and then do a full 10 to reset my 11/14.


The customer the freight is being delivered to. Also referred to as "the receiver". The shipper is the customer that is shipping the goods, the consignee is the customer receiving the goods.


The customer who is shipping the freight. This is where the driver will pick up a load and then deliver it to the receiver or consignee.
