Two break rules on every shift. Most drivers know one of them.
Three years of HGV shifts and I genuinely thought I had the break rules sorted. Four and a half hours of driving, then forty-five minutes. Sorted. Back on the road, tacho recording, everything tidy.
Wasn't quite right. There's a second set of break rules running in parallel — the Working Time Directive requirements under SI 2005/639 — and they run off a different clock entirely. Not driving time. Total working time. Found this out at a compliance refresher in Coventry and spent the drive home thinking about all the shifts where I'd almost certainly been in breach without knowing.
The EU 561 break rule — the one the tacho tells you about
Under Article 7 of EU 561/2006, after four and a half hours of driving you must take an uninterrupted break of at least forty-five minutes. That's the one the tachograph enforces, the one DVSA check at the roadside, and the one most drivers can recite without thinking.
You can split it. Fifteen minutes first, then at least thirty minutes after — both distributed across the 4.5-hour driving window. The split has to be in that order. You can't do thirty then fifteen and call it valid. First portion must be the shorter one.
The critical bit here: the clock runs on driving time. Time on availability at DIRFT, waiting at a bay in Immingham, sitting in a queue at Tilbury — none of that accumulates against the 4.5-hour driving clock. Only actual driving does. So a shift with a lot of waiting built in can mean your EU 561 break window feels very generous.
There's also a multi-manning provision that came in with Mobility Package I. If you're the co-driver on a double-manned trunk and the other driver's at the wheel, you can take your forty-five minutes in the moving vehicle — as long as you're not involved in assisting with the driving. Not touching controls, switched to availability, properly off-duty. A lot of drivers doing A1 night trunks have been using this for years without necessarily knowing it was formalised in law.
The WTD break rule — the one that catches you out
The Road Transport (Working Time) Regulations 2005 — SI 2005/639 — set a completely separate break obligation. Based on total working time, not driving time. Driving, other work, loading, paperwork at the delivery point, time logged as other work rather than availability: all of it counts.
Here's the actual rule. If your total working time on a shift goes beyond six consecutive hours, you need a break of at least thirty minutes. If it goes beyond nine hours total, you need at least forty-five minutes. Each individual break portion counts only if it's at least fifteen minutes — so you can split it, but you can't break it into ten-minute chunks and claim it counts.
Availability doesn't count as working time, so it doesn't push you towards the six or nine-hour triggers. But availability also doesn't count as a break — it's a third category. It's neutral. It doesn't help and it doesn't hurt.
The trigger is six hours. That's lower than most drivers realise. And on a busy shift, it comes around faster than the 4.5-hour driving clock.
Why multi-drop is where this creates real problems
Think about a typical multi-drop out of a Midlands DC. Six stops, Birmingham to Kettering corridor. You start at 05:30 — pre-trip check, load verification, forty minutes of other work before you even get in the cab. Then you're driving. First stop, some waiting, a bit of loading assistance. Second stop the same. By 11:15 you've got six hours of total working time accumulated.
How much of that was driving? Maybe three hours and twenty minutes. Your EU 561 break clock is nowhere near four and a half hours. Under 561 alone, you don't need a break yet.
But you've hit six hours of total working time. The WTD says you need a break. Thirty minutes minimum, at least fifteen minutes in each piece if you split it. The WTD obligation is real, it's in force, and the fact that your tacho doesn't flag it doesn't mean you're compliant.
That's the trap. The six-hour trigger fires first — and because the tachograph doesn't enforce it directly, and because DVSA roadside checks focus heavily on EU 561 records, a lot of drivers don't even know they've missed it.
What counts as working time under the WTD?
Driving obviously counts. Other work counts — loading, admin, helping with the vehicle. Time logged as other work on the tacho counts.
Availability doesn't. This is time when you're waiting and you've been told in advance how long it'll be. If you're at a bay and the TM has told you the slot is in two hours, that period can properly go on availability — provided you're genuinely free to use the time as you like, not required to be on standby ready to move at a moment's notice.
The distinction matters for calculating your working time total. Shifts with a lot of genuine availability built in can sit well below the six-hour WTD trigger even after a long duty period. Shifts where most of the waiting goes on other work — because it was logged that way, or because it was genuinely work rather than waiting — accumulate faster.
If you're not sure which mode should have applied at a given point, the mode on the tachograph record is the record. There's no going back to reassign it unless you can demonstrate a genuine administrative error. Log modes as accurately as you can at the time — it's not just about the EU 561 records, it's about what those records say about your working time totals.
No opt-out. This is the bit most agency drivers don't know.
Workers in the UK can opt out of the 48-hour average weekly working time limit under the general Working Time Regulations 1998. Agencies hand out those opt-out forms routinely. You may well have signed one.
That opt-out doesn't apply to you. Mobile road transport workers — HGV drivers under EU 561 — cannot opt out of the 48-hour weekly average. The opt-out clause in your agency contract is legally worthless for this purpose. I've seen more than a few contracts with exactly this clause included, and every one of them is wrong on that point.
The 48-hour limit is calculated as an average over a 17-week reference period. You can work up to 60 hours in any single week provided the 17-week average stays at or below 48. But there's no option to contract out of the cap. It applies whether you've signed something saying it doesn't or not.
The reference period isn't always clearly defined in agency agreements. Worth asking your TM or agency what reference period they're using for WTD compliance records — and whether they're actually keeping the records they're supposed to.
Night work adds another complication
Night time under the road transport WTD runs from midnight to 04:00 for goods vehicles. If you work during that window, your total working time for that 24-hour period is capped at ten hours. Not driving time — working time.
For tramping work and night trunking, this is significant. A lot of overnight work starts at 23:00 or midnight and runs well into the following morning. If your shift spans midnight to 04:00, you're in the night-time window from the start, and your working time cap for that period is ten hours, not the 48-hour average.
A collective or workforce agreement can extend night work limits. But that requires a formal agreement — not a TM telling you it's fine. Most small fleets don't have collective agreements in place. If yours doesn't, the ten-hour cap applies by default. A 12-hour night trunk shift that includes two hours of other work at the warehouse at 02:00 can push you past it faster than you'd think.
Which rule controls when they conflict?
Both apply simultaneously. You comply with whichever is stricter at any given point. In practice, this means whichever fires first on a particular shift is the one you act on — and you still have to comply with the other one when it fires.
On a pure trunking run with continuous driving and minimal other work time, EU 561 fires first. Take your 45-minute break, which probably also satisfies the WTD obligation at that point anyway. Clean.
On a multi-drop with loading involvement and an early start, WTD fires first. Take thirty minutes before you hit six hours of working time. When you then hit 4.5 hours of driving — probably some time later — you may need another break under 561 if what you took earlier doesn't qualify.
A break that satisfies both is possible. Forty-five minutes taken after five hours of working time and 4.5 hours of driving covers both obligations simultaneously. The problem is that on a mixed shift, the two clocks often don't line up conveniently — and a break that satisfies 561 might not satisfy the WTD if it came too late relative to the six-hour working time trigger.
Records and what operators are supposed to hold
The tachograph download covers driving time and activity modes. That's not the same as a full WTD working time record. Operators are required to keep WTD records covering the complete reference period — 17 weeks — and those records must be retained for two years.
At a premises inspection, DVSA ask for WTD compliance records. A lot of small fleets produce the tachograph analysis and stop there. That isn't sufficient. You need records that account for all working time, including any work that didn't appear on the tacho — time at the depot before or after a shift, admin that wasn't recorded on the card.
This is where spreadsheet-based compliance falls apart. A DVSA inspection at a 12-vehicle fleet I knew in Coventry turned up exactly this gap. The tacho downloads were fine. The WTD reference period records weren't in any kind of order. The TM had been treating the tachograph analysis as the complete picture. It wasn't.
