Most drivers can recite the 9-hour day and the 4½-hour break. The rules that still catch people out sit at the week and fortnight level: when your weekly rest can shrink, when you must pay the reduction back, and how the 90-hour cap across two weeks quietly limits “next week” even when this week still has room.
This post zooms in on those pieces of EU 561/2006 (and the UK drivers’ hours framework that follows the same numbers for most HGV work). It is not legal advice. For the authoritative text see EUR-Lex and GOV.UK drivers’ hours, or your transport manager.
The week in one glance
| Limit | Number | Notes |
|---|---|---|
| Weekly driving | 56 hours max | Monday 00:00 – Sunday 24:00 (ISO week) |
| Fortnight driving | 90 hours max | Any two consecutive weeks |
| Regular weekly rest | 45 hours | The default weekly rest |
| Reduced weekly rest | 24 hours minimum | Allowed — but you owe compensation |
Daily rules (9h/10h driving, daily rest, breaks) still apply inside every week. This article is about the weekly rest and multi-week driving layer on top.
Weekly rest — regular vs reduced
Regular weekly rest — 45 hours
The standard: at least 45 hours of weekly rest. That is the clean pattern — finish the week, take a proper weekly rest, start the next cycle without a debt.
Reduced weekly rest — 24 hours
You may take a reduced weekly rest of at least 24 hours instead of 45 — but the difference is not free.
Compensation rule (plain English):
The reduction must be compensated by an equivalent period of rest taken en bloc before the end of the third week following the week in which the reduced rest was taken.
Example shape (illustrative):
- Week 1 — you take 24h weekly rest instead of 45h → you “owe” 21 hours of compensation rest.
- That 21 hours must be attached to another rest period and completed by the end of week 4 (third week following week 1).
Miss the compensation window and you have not just had a short weekend — you have a compliance problem.
Other weekly-rest points drivers forget
- Weekly rest is about rest, not “I only drove a bit.” Other work and POA are not weekly rest.
- You cannot “average” two short rests into one 45-hour rest after the fact without following the compensation rules.
- Ferry / train derogations and multi-manning have extra detail — confirm with your operator if that is your work. This post sticks to the core land pattern.
Why reduced weekly rest feels fine — until it isn’t
Reduced rest is popular because the work is there and the ferry is booked. The trap is stacking:
- Multiple reductions close together
- Compensation rest left until the last legal day
- Starting a heavy fortnight while still carrying rest debt
HGV Time Pilot’s card analysis and Daily Compliance Review are built to surface rest-related warnings and infringements when the pattern on the card does not add up. Do not wait for a red day to discover a compensation deadline you forgot.
The 56-hour week
In any week (Monday–Sunday):
- You must not drive more than 56 hours.
That sits beside the daily caps (9h, or 10h on at most two days). You can be legal every day and still blow the week if you string long days together.
On the Can I drive now? card, This week remaining driving reflects the 56h weekly cap from your imported card data.
The 90-hour fortnight — the quiet limiter
Across any two consecutive weeks, total driving must not exceed 90 hours.
Why it feels sneaky:
- Week A looks fine at 50h driven.
- Week B still has “room” under 56h in isolation.
- But 50 + planned week-B hours can smash the 90h cap.
That is why HGV Time Pilot shows both:
| Label | Meaning |
|---|---|
| This week | Headroom under the 56h week |
| Next week | What you could still drive next week after accounting for the fortnight |
| Two-week total | Headroom under the 90h limit across the two-week window |
If another app shows a bigger “this week” number than you expect, compare it with Two-week total — some tools blend fortnight logic into a single weekly display.
Weeks are Monday–Sunday (London ISO week) in Time Pilot.
How HGV Time Pilot helps
Live shift — Android timer
The shift timer coaches today (breaks, WTD tiers, shift length). It cannot see your full fortnight from tachograph history until card data is on the account.
After the card download
Download your card, then:
- Read What’s left on Can I drive now? — today / week / next week / two-week total.
- On Pro, open Daily Compliance Review for days that look short on weekly rest.
- Generate a weekly or fortnight PDF from the Reports hub when you want a file for your operator.
- Ask Time Pilot AI “how much can I drive next week?” only when card data is fresh.
Common pitfalls
- Treating 24h reduced rest as “job done.” You owe the difference back on the clock.
- Leaving compensation to the last weekend. Illness, traffic, or a late load and the window closes.
- Planning next week off this week’s 56h alone. Always check the 90h fortnight.
- Confusing calendar weeks with “my pay week.” The regulation week is Monday–Sunday for these limits.
- Ignoring rest debt while staring at driving totals. You can have driving hours left and still be blocked by rest rules — status headlines like weekly rest required exist for a reason.
A practical planning routine
- Mid-week: glance at This week and Two-week total after a card refresh.
- Before accepting next week’s work: check Next week remaining — that is fortnight-aware.
- If you took a reduced weekly rest, diary the compensation deadline (end of the third following week) like a ferry booking.
- Friday: download the card, skim DCR for rest-related warnings.
- Optional: file a fortnight PDF every other Sunday.
Frequently asked questions
Can I take two reduced weekly rests in a row?
The regulation allows reduced weekly rest under conditions — but compensation debts stack in real life even when each reduction is individually permitted. Confirm patterns with your transport manager; do not invent a “always 24h” lifestyle.
Does POA count toward weekly rest?
No. Weekly rest is rest. POA is availability / working-time territory under WTD, not a substitute for weekly rest under EU 561.
Is the fortnight exactly 14 calendar days from today?
The driving limit is about any two consecutive weeks (Mon–Sun weeks), not a floating 14×24h window from this minute. Use the dashboard’s two-week figures rather than mental arithmetic on the hard shoulder.
Where do ferry rules fit?
Ferry and train interruptions of rest have specific provisions. This article does not cover every derogation — ask your operator if that is your regular work.
Will the app stop me starting the engine?
No. Status and DCR advise; the tachograph and your decisions control the vehicle.
