8/2 and 7/3 Splits, Worked Hour by Hour
Four days drivers actually live. Each one shows the timeline, the recalculation anchor, and what's left in the tank afterward.
1 · The classic 8/2 — parked early, finishing at night
6:00 AM on duty · 6 h driving + 1 h loading · 1:00–3:00 PM off duty (2 h, 1st break) · 5 h driving · 8:00 PM–4:00 AM sleeper berth (8 h, 2nd break)
Valid 8/2. Anchor at 3:00 PM (end of first break). On-duty between breaks: 5 h → window left at 4:00 AM: 9 h, driving must end by 3:00 PM + 14 + 8 = 1:00 PM. Driving: 6 + 5 = 11 used → 0 h left. You're parked on window, not wheels — a full 10-hour reset before the next drive.
2 · The shipper-delay 7/3 — turning a 3-hour wait into qualifying rest
7:00 AM on duty · 3 h driving · arrive shipper 10:00 AM, trailer not ready · 10:00 AM–1:00 PM off duty (3 h, 1st break) · 1 h loading · 4 h driving · 8:00 PM–3:00 AM sleeper berth (7 h, 2nd break)
Valid 7/3. Anchor at 1:00 PM. On-duty between: 5 h → window left at 3:00 AM: 9 h, deadline 1:00 PM + 14 + 7 = 7:00 AM next day. Driving: 3 + 4 = 7 → 4 h left. Without the split, sitting at that dock would have burned your window to nothing by 9:00 PM.
3 · Long break first — the appointment-day pattern
9:00 PM–4:00 AM sleeper berth (7 h, 1st break) · 7:00 AM on duty · 2 h driving + 1 h at receiver · delivery window 10:00 AM–2:00 PM · 12:00–3:00 PM off duty (3 h, 2nd break)
Valid. Anchor at 4:00 AM. On-duty between: 3 h → window left at 3:00 PM: 11 h, deadline 4:00 AM + 14 + 3 = 9:00 PM. Driving used: 2 h → 9 h left. You deliver, rest 3 hours mid-afternoon, and still own most of a day.
4 · The near-miss 7/2.5 — the pairing that quietly fails
6:00 AM on duty · 5 h driving · 11:00 AM–1:30 PM off duty (2.5 h) · 4 h driving · 5:30 PM–12:30 AM sleeper berth (7 h)
Not valid. The two breaks total 9.5 hours — half an hour short. Both breaks count back into the window as ordinary off-duty, your original 14-hour window stands, and by 12:30 AM you're 20 hours past your 6:00 AM start: no driving left, window gone. Add 30 minutes anywhere and the same day becomes a legal 7/3.
The deadline moves with the order of your breaks even though legality doesn't. Whichever break comes
first sets the anchor — run both orders through the
calculator before you commit to one.
FAQ
Is 8/2 better than 7/3 for split sleeper?
Neither is better in the abstract. The 8/2 is the classic pattern for parking early and finishing a run at night; the 7/3 shines when a long shipper or receiver delay can be logged as the shorter qualifying break.
Can the 2-hour break come first?
Yes. Breaks can be taken in either order. The recalculation anchors to the end of whichever break came first, so the order changes your deadline math, not the legality.
Can I split 8/3 or 9/2?
Yes. Any pairing with 7+ consecutive sleeper-berth hours, no period under 2 hours, and a combined 10+ hours qualifies. The named options are just the minimum patterns.
