HGV Weekly Rest Periods: Daily Rest, Weekly Rest, and the WTD Rules
Rest period rules trip up small operators more often than driving limits do. The driving limits are clear numbers — 9 hours, 10 hours, 56 hours. The rest rules involve overlapping daily and weekly cycles, the option to reduce rest, and a separate Working Time Directive layer that runs alongside the drivers' hours rules.
This guide covers all of it — what counts as rest, how the daily and weekly cycles interact, and where small operators most commonly slip up.
General guidance, not legal advice. Rest rules under EU drivers' hours apply to most goods vehicles over 3.5t in commercial use; vehicles operating under GB domestic rules or specific exemptions may differ. Always check the rules that apply to your operation against current DVSA guidance.
What Counts as Rest
Rest, in EU drivers' hours rules, means uninterrupted time during which the driver can freely dispose of their time. They can't be driving, doing other work, or on call.
Rest can be taken:
- At home
- In an external location (hotel, B&B)
- In the cab — but only if the cab has suitable sleeping facilities and is stationary
Rest cannot be taken:
- While driving (obviously)
- While on duty waiting for a load
- During a break (a break is separate from rest — see our HGV driving hours guide for the break rules)
The distinction matters because at a roadside check, DVSA examiners look at the tachograph mode for each period and can challenge time logged as rest if the vehicle was moved or other work was being done.
Daily Rest
A driver must take a regular daily rest of at least 11 hours in any 24-hour period.
The 24-hour period starts when the driver first starts work after the previous daily or weekly rest. If a driver started work at 06:00 on Monday after sufficient rest, the next daily rest must finish by 06:00 Tuesday — meaning the latest the rest can start is 19:00 Monday.
The 11 hours can be split into two periods:
- A first period of at least 3 hours
- A second period of at least 9 hours
- Both periods must be taken within the 24-hour cycle
If the driver splits the rest, the total daily rest must be at least 12 hours (3 + 9). Splitting doesn't reduce the total.
Reduced Daily Rest
A driver can take a reduced daily rest of 9 hours instead of 11 hours, up to 3 times between any two weekly rest periods.
Reduced daily rests:
- Cannot be split
- Don't have to be paid back later (unlike reduced weekly rest)
- Allow a longer working day — the duty period can extend to 15 hours when followed by a 9-hour rest
This is what makes "15-hour days" possible — the maths only works with reduced daily rest. Without it, an 11-hour rest off a 13-hour duty leaves no margin. For a worked guide to the daily rest rules — including when reduced rest can be taken and how the split-rest option works — see our daily rest period rules guide.
Multi-Manning Rule
If two drivers are crewing the same vehicle, the daily rest must be at least 9 hours within 30 hours of starting work. This gives multi-manning operators an effective 21-hour duty cycle, used mostly on long-distance trunking runs.
Weekly Rest
After 6 consecutive 24-hour periods of duty, a driver must take a weekly rest period.
There are two types:
- Regular weekly rest: at least 45 hours
- Reduced weekly rest: at least 24 hours — but with rules about how often and how it must be paid back
How Often Reduced Weekly Rest Is Allowed
In any 2 consecutive weeks, the driver must take:
- At least 1 regular (45-hour) weekly rest, AND
- At most 1 reduced (24-hour) weekly rest
You can't have 2 reduced weekly rests in a row. The pattern is: regular → reduced → regular → reduced (or any pattern that doesn't put two reduced rests back-to-back).
Paying Back Reduced Weekly Rest
The hours lost from a reduced weekly rest must be compensated as a block within the third week after the reduction.
Example: a driver takes a 24-hour weekly rest in week 1 (saving 21 hours). Those 21 hours must be added to a daily or weekly rest in weeks 2, 3, or 4 — taken as a single uninterrupted block alongside another rest period.
This gets messy fast. Most small operators avoid reduced weekly rest unless absolutely necessary, because tracking the compensation across weeks creates a paper trail of obligations that's easy to miss.
The Working Time Directive Layer
Separate from EU drivers' hours, the Road Transport (Working Time) Regulations 2005 apply to mobile workers in scope of EU drivers' hours rules. The DVSA Working Time Directive guidance explains the framework.
The key WTD limits:
- Average 48 hours/week of working time over a 17-week reference period
- Maximum 60 hours of working time in any single week
- Minimum 30-minute break after 6 hours of work; 45-minute break after 9 hours
- Maximum 10 hours of night work in any 24-hour period (where night = midnight to 04:00 typically, defined per operation)
"Working time" under WTD is broader than "driving time" under drivers' hours. It includes loading, unloading, paperwork, vehicle checks — anything done for the employer.
How WTD and Drivers' Hours Interact
Both sets of rules apply simultaneously. A driver must comply with whichever rule is stricter at any given moment.
Two practical examples:
- A driver takes a 45-minute break after 4.5 hours of driving (drivers' hours rule). That break also counts toward WTD breaks — but only if it actually averages out to the WTD requirement of a 30-minute break after 6 hours of work. Sometimes the WTD break clock has its own count.
- A week with 56 hours of driving (the maximum under drivers' hours) might still be 60+ hours of working time once loading and paperwork are included. That breaches WTD. So drivers in busy weeks may need to come well below the 56-hour driving limit just to stay inside the 60-hour WTD weekly cap.
Common WTD Failures
- Tracking only driving time, ignoring loading/unloading and paperwork
- Forgetting that the 30-minute / 45-minute break thresholds in WTD differ from the 4.5-hour break under drivers' hours
- Running 60+ hour weeks without checking the 17-week average
What This Means for Sole-Trader Operators
For an owner-operator running 1-5 vehicles, the practical implications:
- Default to regular weekly rest (45 hours). Reduced weekly rest creates compensation tracking that's easy to lose.
- Default to regular daily rest (11 hours). Use reduced daily rest sparingly and only when it's planned in advance.
- Track working time, not just driving time. Running a tachograph analysis system that flags WTD breaches is the cleanest way — manual spreadsheets miss things.
- Audit yourself quarterly. The O-licence compliance checklist covers what to review.
- Maintain the maintenance schedule. Drivers' hours sit alongside vehicle PMI as the two areas where small operators most often slip up — our vehicle maintenance planner guide covers the inspection cadence side.
Tachograph downloads sit at the centre of all this. Without timely downloads, you can't see what your drivers are actually doing — and DVSA can. See our tachograph downloads guide for the procedural side.
