Under EU Regulation 561/2006 (retained in UK law), HGV drivers can split their daily rest into two parts using the 3+9 rule: a first period of at least 3 hours followed by a second period of at least 9 hours, giving a total minimum of 12 hours within each 24-hour period. The order matters — 3 hours first, then 9 hours — and you can't do it the other way round. This guide breaks down exactly how split daily rest works, how it compares to regular and reduced daily rest, and the mistakes that catch drivers out.
What Is a Regular Daily Rest Period?
A regular daily rest is 11 continuous hours within each 24-hour period. That 24-hour window starts from the end of your previous daily or weekly rest — not from midnight, and not from when your shift began.
So if you finished your last rest at 06:00 on Monday, your next daily rest of 11 hours must be completed by 06:00 on Tuesday. Simple enough.
Here's the thing most new drivers miss: a daily rest is not a weekly rest. Even if you take a full 11-hour daily rest, it doesn't count towards your weekly rest requirement. You still need at least 24 hours for a reduced weekly rest or 45 hours for a regular one. They're separate obligations under the regulations.
For a full breakdown of weekly rest rules and the 144-hour limit, see our complete EU driving hours guide.
What Is a Reduced Daily Rest?
A reduced daily rest is any rest period of at least 9 continuous hours but less than 11 hours. You're allowed up to 3 reduced daily rests between any two consecutive weekly rest periods.
Unlike reduced weekly rests, there's no compensation requirement. You don't need to "pay back" those lost hours later. Once you've taken your 9 hours, you're good to go.
But keep count. Three is the limit. If you're working a full fortnight between weekly rests and burning through your reduced rests early in the week, you'll have no flexibility left when you need it.
How Does Split Daily Rest Work? (The 3+9 Rule)
This is the option most drivers either don't know about or get wrong. Instead of taking your daily rest in one block, you can split it into exactly two periods:
- First period: minimum 3 hours
- Second period: minimum 9 hours
- Total: minimum 12 hours (not 11)
The order is fixed. You take the shorter rest first, then the longer one. You can't take 9 hours then 3 hours — that won't count as a valid split rest.
When would you actually use this?
Split rest is brilliant for drivers who start early, have a gap in the middle of the day, then need to work again in the evening. A typical scenario:
- 05:00–09:00 — Morning deliveries (4 hours driving)
- 09:00–12:00 — Rest period 1 (3 hours)
- 12:00–17:00 — Afternoon collections (5 hours work)
- 17:00–02:00 — Rest period 2 (9 hours)
Total rest: 12 hours. Both periods within the same 24-hour window. Fully compliant.
Does a split rest count as a reduced rest?
No. A properly taken split daily rest (3+9 = 12 hours) is treated as a regular daily rest, not a reduced one. It doesn't eat into your allowance of three reduced rests per working period.
Does a split daily rest count towards my weekly rest?
No. Daily rest and weekly rest are completely separate under the regulations. A split daily rest won't reset your 144-hour counter either — only a weekly rest of 24 hours or more does that.
Comparison: Regular vs Reduced vs Split Daily Rest
| Rest Type | Minimum Duration | Continuous? | Limit Between Weekly Rests | Compensation Required? |
|---|---|---|---|---|
| Regular daily rest | 11 hours | Yes — one block | No limit | No |
| Reduced daily rest | 9 hours | Yes — one block | Max 3 times | No |
| Split daily rest (3+9) | 12 hours total (3h + 9h) | No — two blocks | No limit | No |
Notice that split rest actually requires more total rest (12 hours) than either regular (11 hours) or reduced (9 hours). The trade-off is flexibility in when you take it.
Multi-Manning Daily Rest Rules
When two drivers are in the cab together (multi-manning), the daily rest rules change. Each driver must take at least 9 hours of daily rest within a 30-hour period — not the usual 24 hours.
A driver who isn't at the wheel records that time as a period of availability on the tachograph — not as rest. Under Article 4(f) of EU 561/2006, rest requires the driver to "freely dispose of their time," which doesn't apply when you're required to be available in a moving vehicle. If the second driver is doing paperwork, helping with loading, or navigation, that's other work. The co-driver's time only counts as a break (not rest) during the first 45 minutes, provided they perform no work.
The extended 30-hour window makes multi-manning runs more flexible, but both drivers still need their 9 hours. No exceptions.
Common Mistakes with Daily Rest
This is where most drivers get caught out. Here are the errors enforcement officers see again and again:
1. Getting the split order wrong
Taking 9 hours first and then 3 hours doesn't satisfy the split rest rule. It must be 3 hours first, then 9 hours. Get it backwards and the entire rest is invalid — you'll be treated as having had no qualifying daily rest at all.
2. Splitting into more than two periods
You can't take three separate rests of 4 hours each and call it a day. Split rest means exactly two periods. If you break it into three or more chunks, none of them count as a valid daily rest.
3. Thinking daily rest resets the weekly rest clock
It doesn't. Your 144-hour rule timer keeps running regardless of how many daily rests you take. Only a proper weekly rest (minimum 24 hours for reduced, 45 hours for regular) resets that counter.
4. Agencies booking back-to-back shifts without rest gaps
If you work through a driver staffing agency, you and the agency both share responsibility for ensuring daily rest is taken. An agency that books you on a shift finishing at 22:00 and another starting at 06:00 the next day has only given you 8 hours — that's not enough for any type of daily rest. Drivers need to push back, and agencies need systems that flag these conflicts.
Tools like ShiftOwt help both drivers and agencies by making availability and rest periods visible in one shared calendar, so scheduling conflicts get caught before they become compliance breaches.
5. Using up all three reduced rests too early
You get three reduced daily rests between weekly rest periods. Burn them all in the first three days and you're locked into 11-hour (or 12-hour split) rests for the remainder. Plan ahead.

How to Record Split Daily Rest on Your Tachograph
Your tachograph needs to show two distinct rest periods within the 24-hour window. With a digital tachograph, this happens automatically when you set the mode to rest. With an analogue chart, make sure each rest block is clearly marked.
The key is that an enforcement officer must be able to see the 3-hour block and the 9-hour block as two separate, clearly defined periods. Any ambiguity — overlapping entries, unclear mode switches — can lead to questions you don't want to answer at the roadside.

Planning Your Rest with ShiftOwt
Whether you're a solo driver managing your own schedule or an agency coordinating dozens of HGV drivers across different operators, keeping track of daily rest — especially split rests — gets complicated fast.
ShiftOwt's availability calendar lets drivers mark their rest periods and working hours so everyone's on the same page. Agencies can see at a glance whether a driver has had proper daily rest before assigning the next shift, and drivers get a clear record of their compliance history.
It won't drive the lorry for you. But it'll make sure you're legal when you do.
Frequently Asked Questions
Can I split my daily rest into different patterns, like 4+9 or 5+9?
Yes — as long as the first period is at least 3 hours and the second period is at least 9 hours, the rule is satisfied. A 4+9, 3+10, or 5+9 split all work. The minimums are 3 and 9; anything above those minimums is fine. But a 4+8 split wouldn't count, because the second period must be at least 9 hours. The shorter block always comes first, and the total must be at least 12 hours.
Does a split daily rest count as one of my three reduced rests?
No. A valid split daily rest (3+9 = 12 hours minimum) counts as a regular daily rest. It doesn't use up one of your three reduced daily rest allowances. In fact, because the total is 12 hours rather than 11, you're actually resting more than a standard regular daily rest.
What's the difference between daily rest and weekly rest for HGV drivers?
Daily rest (regular: 11 hours, reduced: 9 hours, split: 3+9 = 12 hours) must be taken within each 24-hour period. Weekly rest (regular: 45 hours, reduced: 24 hours) must be taken according to the weekly rest period rules and the fortnight rule. A daily rest — no matter how long — never counts as a weekly rest and doesn't reset your 144-hour clock. They're separate legal requirements under EU Regulation 561/2006.
