A reduced weekly rest feels free. Take 24 hours off instead of 45. Get back behind the wheel Sunday evening. Pocket an extra shift.
It's not free. You've borrowed 21 hours from your future self, and the rulebook has specific conditions on when and how you pay it back. Get those wrong and the infringement shows up on a download four weeks later, usually the week you'd forgotten all about it.
I've taken reduced weekly rests dozens of times. Tramping out of Lymm, you plan them in. I've also been hauled up by a transport manager for getting the compensation wrong — once because I attached the compensation to the wrong rest, once because I'd run out of weeks. Here's the rule, written for drivers who want to actually use reduced weekly rest without it biting them later.
The basic deal under Article 8
EU Regulation 561/2006 — still the retained law in GB — gives you two types of weekly rest:
- Regular weekly rest: 45 hours uninterrupted
- Reduced weekly rest: at least 24 hours uninterrupted
You can take one reduced in any two consecutive weeks. Two regulars back-to-back is fine. Two reduceds back-to-back is not.
The bit everyone half-remembers: if you take a reduced, you owe the shortfall. Forty-five minus 24 equals 21. Twenty-one hours of compensation, owed back.
That's not the catch. The catch is how you pay it.
The 9-hour attachment rule
The compensation cannot stand on its own. You cannot just book a 21-hour sleep somewhere and call it paid back. The rule is specific: the compensation must be taken en bloc — in a single stretch — and attached to another rest period of at least 9 hours.
Read that again. At least 9 hours. That covers:
- A regular daily rest (11 hours) — works
- A reduced daily rest (9 hours) — works
- A split daily rest (3+9) — the 9-hour portion qualifies as the attachment
- A weekly rest (regular or reduced) — works, and common
What it doesn't cover: a casual break, a multi-manning rest period under 9 hours, or a shift where you've run out of WTD hours but haven't booked a formal daily rest.
So if you owe 21 hours compensation, you take a regular daily rest of 11 hours and tack 21 hours onto it. Total 32 hours in one uninterrupted block. Or you tack it onto a regular weekly rest of 45 and make a super-rest of 66 hours. The point is it's attached. One continuous block.
The deadline — end of the third week following
Here's where I see drivers lose track.
Say you take a reduced weekly rest in Week 10 of the year. The compensation must be completed — not started, completed — before the end of Week 13.
That's the end of the third week following the week in question. Week 10 is the week of the reduction. Weeks 11, 12, and 13 are your three weeks to pay it back. End of Week 13 is the deadline.
In tacho terms, a week runs Monday 00:00 to Sunday 24:00. If your reduced rest straddles the weekend — say it starts Saturday afternoon and ends Sunday afternoon — you've still reduced in that week. The compensation clock starts ticking from the start of the following Monday.
Three weeks sounds like loads. It isn't, especially if you're tramping and your rest pattern is tight. I've run weeks where every daily rest was 9 hours reduced and every attached compensation would have blown a planned load. You have to plan the payback the same day you plan the reduction.
How I plan it — a real fortnight from last month
Let me walk through a real example. I ran the following fortnight out of Lymm in late March.
- Week A: Mon–Sat working, tipping in Glasgow Saturday afternoon. Weekly rest started Saturday 16:00. Took a reduced 24 hours. Back on at Sunday 16:00 for a Carlisle run.
- Week B: Mon–Fri. Took a regular 45-hour weekly rest Friday evening through Sunday evening. Attached the 21-hour compensation from Week A to the start of that 45 hours, so the whole block was 66 hours.
Paid back inside one week. Clean. The tacho analyser at the yard flagged the reduction, and when it saw the 66-hour block the next week it reconciled automatically.
Where I've cocked this up before: I took a reduced rest in Week A. Week B I was busy. Week C I was busy. Week D rolled around and the reconciliation was overdue. Now I'm trying to find a 32-hour window to bolt the compensation on, and my planner's already given me Wednesday loads. Panic. I ended up taking a regular weekly rest on the wrong day just to get the shortfall attached before the deadline. Lost earnings. My own fault.
Common mistakes I see
1. Attaching to the wrong rest type. The attachment rest must be at least 9 hours. If you've just finished a split daily rest (3 + 9), the 3-hour portion is not 9 hours, so you can't attach to it. The 9-hour portion is. Attach to the 9-hour half.
2. Splitting the compensation. You cannot owe 21 hours and pay back 10 hours one day, 11 hours another. It must be en bloc. One single stretch, attached to a 9-hour-plus rest. Split it and you've not compensated at all — now you owe 21 hours still, plus you've failed to provide proper daily rests in between.
3. Missing the deadline. End of third week following. I've seen drivers count three weeks inclusive of the week they reduced in, which gives them only two weeks to pay back. Don't. The week of the reduction is Week 0 for counting purposes. Three weeks after is the deadline.
4. Taking two reduceds in consecutive weeks. Not allowed. If you took a reduced this week, next week must be a regular 45-hour. The rule is one reduced in any two consecutive weeks — so if Week 10 was reduced, Week 11 must be regular.
5. Forgetting to log the reconciliation. The tacho analyser sees a reduced rest. It flags. It needs a note — "21 hours compensation attached to weekly rest commencing [date]" — or the flag never clears. Six months down the line DVSA ask for records, the flag's still live, operator's OCRS takes the hit.
What this looks like on a card download
When a transport manager downloads your card, the analyser (Tachomaster, TruTac, FleetCheck, whichever) groups your rests by week and checks the balance. A reduced weekly rest creates a debit. A compensation block — at least 21 hours, attached to a 9-hour-plus rest, within the deadline — creates a credit. The two should match and clear.
If you've taken 3 reduced weekly rests in 5 weeks and only paid back one, the analyser shows two open debits. That's two live infringements. They sit there until reconciled or until they age out of the record-keeping window.
DVSA can look back at the driver card for 28 days at the roadside. But operators must retain records for 12 months. The Traffic Commissioner can call a Public Inquiry on patterns stretching back years. The downloads tell a story.
When reduced rest is actually worth it
Look, I'm not telling you never to take a reduced. Reduced rests are brilliant for expedited kit, for container runs timed to ferry sailings, for any week where the extra 21 hours back at work is worth more than the hassle of the reconciliation.
But plan the payback the same moment you plan the reduction. If you can't see where the compensation bolts onto a 9-hour-plus rest within the next three weeks, don't take the reduced. Take a regular. Your future self will thank you.
The 12-vehicle fleets I've run compliance for all use the same rule of thumb: book the reduced rest and the compensation at the same time in the planning software. If the planner can't see where the bolt-on goes, the reduction doesn't get approved. That stops about 90% of the infringements I used to see.
The short version
- 24-hour reduced weekly rest legal, one in any two consecutive weeks
- Compensation equals the shortfall (up to 21 hours if you went to the floor)
- Compensation must be en bloc, attached to another rest of at least 9 hours
- Deadline is end of the third week following the week of reduction
- Log the reconciliation on the analyser so the flag clears
Get those five points right and reduced weekly rest stops being a trap.
