Split Reset Question.

OK. Here's the deal. From the information I provide can one of you smart drivers tell me (roughly) how much time I should have after about 9 hours in the sleeper berth. I often wake up and my HOS tells me I have x amount of drive time and x amount of on duty time even though I haven't completed a full 10 hours. I want to know how to figure out in advance how much time I'm going to have after 8-9 hours in sleeper. This is an example from two days ago:

On duty/pretrip: 3:01 Driving: 3:14 - 7:48 On duty/customer check in: 7:48-8:19 SB/customer unloading: 8:19-12:32 Driving: 12:32 - 13:56 On Duty/post trip: 13:56 - 14:08

From the info provided can you tell me how much drive time I should have after 9 hours in SB? And how you figured it out. I really want to know.

I sent Brett an article that explains it very easily but he hasnt posted it yet.

If im reading that right, you spent 4 hours off duty/sleeper at the customer then drove about an hour and a half. So you will get back 9.5 hours of drive time after 8+ consecutive hours in the sleeper.

11 hours drive time MINUS the hours you drove between your two breaks. equals what you will get back after the second break

so 11 - 1.5 you drove between the customer and your 8+ consecutive sleeper equals 9.5

In order to know the end of 14 hour clock add 22 hours to the time you got out of the break. In this case 12:32. This means your 14 clock will end 10:32 the next day.

The reason is the 8 sleeper pauses your 14 hr clock. So at the end of your FIRST break of 2+ hours, you add 22 which is your 14 clock + 8 sleeper.

If you took the 8 sleeper first, you add 14 to the end of the first break.. so if you got out of the 8 sleeper at 12:32, you would add 14 hours which would give you 02:32.

Anytime you take 8 sleeper without a 2 hour break, you get back exactly what you had when you went into sleeper.

make sense?

Ha! Easy for you to say! Lol. I didn't know you could use two hours on the front end of the split. I will certainly take a more thorough look at the info you just provided and use it to figure out what I should expect to see about 8 hours from now when I wake up and see my available HOS. With any luck I will not be surprised. Thanks!

Oh, and yes, Rainy, your numbers were spot-on with what my HOS read.

The split is hard to understand, but once you get it it'll be like a light bulb coming on.

A split is composed of two things:

- at least 2 consecutive hours off duty, sleeper berth , or combination of the two.

- at least 8 consecutive hours in sleeper berth. This also pauses your clock from the moment you went into sleeper berth.

Either segment can be done first. Once you complete both segments, your clocks will always reset from the end of the previous segment .

In your example you fulfilled the first segment by going into SB/customer unloading for at least two hours, ending at 12:32 when you started driving. After spending at least 8 hours in the sleeper, you fulfilled the second segment. Thus your clocks automatically reset at the end of the previous segment , or 12:32. The 8 hours in the sleeper also paused your clock, which is why you had 9.5 drive hours left after the sleeper.

It's confusing, I know. But there's more...

You can also do these segments consecutively, ie: 2/8/2/8/2 etc.

Again, after each segment is completed, your clocks will reset at the end of the previous segment. So if you got up after your 9 hours in the sleeper and drove 2 hours, then spent two hours off duty at the next customer, guess what? You just completed another split, and your clock resets from the end of the previous segment (9hrs sleeper).

The phrase I keep repeating: " your clocks reset at the end of the previous segment is an important one to remember. Once you have that drilled into your brain, you can begin to understand how the split works. At least that's what it took for me to get it.

make sense?

But you can't get back 9 hours. You can only be on duty 8 hours between breaks. The DOT clock will never say more than 8 hours. So if you do as the OP states he will get back 8 hours and have to take another 30 to get the rest of drive time.

At least I think so.

Brandon, these conversations about split sleeper always get confusing. It's especially confusing when people try to help when they really don't understand the rules. Don't confuse "on duty" time with "drive time."

You can only be on duty 8 hours between breaks.

That's not a factual statement. You can be "on duty" for as long as you need to be, even in excess of the eight hours and the seventy hour clock. So you can get back more than eight hours.

Yes it is a factual statement. If you get on duty, 8 hrs later you aren't moving that truck until you take a 30.

My DOT clock resets to 8 hours after a 10 hour break. If I drive 4 hours then take 8 hrs in the sleeper, I get 7hrs back. If I drive for 1 hr and take 8hrs, I get 8 hrs on the DOT clock. Yea I get more drive time, but not flat. I still have to take another 30 to get it.

I guess I'm being too technical.
