Went self-employed three years ago. Registered as a sole trader, got the van insured, sorted the CPC, lined up a couple of agencies for work. And somewhere in the back of my head was the comfortable assumption that, now I was my own boss, the Working Time Directive was somebody else's paperwork problem.
Spoke to a transport solicitor at an industry event about eighteen months in. Mentioned this. She looked at me in a way that suggested I was not the first driver to have made this assumption and said: "Regulation 4 of the Road Transport (Working Time) Regulations 2005 specifically covers self-employed drivers. Same reference period. Same maximums."
Then she asked if I'd been keeping records. I had not been keeping records.
So here's the thing that a lot of self-employed HGV drivers don't know, or have convinced themselves isn't true: the Working Time Directive, as implemented in road transport law, applies to you whether you're employed, agency, or sole trader. The opt-out that exists for some industries doesn't work the way most drivers assume in road transport. Let me explain what the rules actually are.
The Road Transport (Working Time) Regulations 2005
The Working Time Directive as it applies to HGV drivers is not implemented through the general Working Time Regulations 1998 (the ones most people know about). Road transport has its own specific regulations: the Road Transport (Working Time) Regulations 2005, which implemented EU Directive 2002/15/EC. These are retained in UK law post-Brexit.
Regulation 4(1) of the 2005 Regulations sets out the weekly working time limit for road transport workers. And it explicitly covers both categories: "mobile worker" (employed drivers) and "self-employed driver." The same working time limits apply to both.
This is the part most self-employed drivers miss. They hear "Working Time Directive" and they think about the opt-out that exists in general employment law, or they assume that because they're not an employee, it doesn't apply. Neither assumption is correct in road transport. Parliament chose to include self-employed drivers in the 2005 Regulations, and that inclusion has been maintained in retained law.
What the limits actually are
The WTD working time limit for mobile workers (and self-employed drivers) is:
- An average of 48 hours per week, calculated over a 17-week reference period
- An absolute maximum of 60 hours in any single week — this is the hard ceiling that can never be exceeded, regardless of the reference period average
- A maximum of 10 hours in any 24-hour period if you regularly work nights (between midnight and 04:00)
The 48-hour average is the target for the reference period. The 60-hour single-week maximum is the hard stop. These are two different limits and both apply.
Working time in this context includes: time driving, time at the wheel when stationary (loading, waiting at a depot), time spent in general duties related to the vehicle or its load, and time spent on administrative tasks required by your operation. It does NOT include breaks (which don't count as working time), rest periods, or annual leave. For self-employed drivers, it also doesn't include time spent on business administration not directly related to the vehicle — accounts, invoicing, that kind of thing.
The 17-week reference period
The 48-hour average is calculated over a rolling 17-week period. A good week (35 hours) offsets a bad week (58 hours) in the average. This is the same mechanism that applies to employed mobile workers — I wrote about the mechanics in detail in the WTD reference period post.
For a self-employed driver, the reference period calculation is your own responsibility to track. There's no employer managing it for you. And because nobody's watching your average on your behalf, it's easy to drift into a pattern where the 17-week average is creeping towards 48 without you noticing — particularly if you're taking on as much work as you can get in the first year or two of being self-employed.
The difference between WTD and 561/2006
These are separate pieces of legislation with separate obligations. EU 561/2006 governs driving hours — the 9-hour daily limit, the 4.5-hour break rule, the 56-hour weekly driving limit, the 90-hour fortnightly cap, the weekly rest. The WTD governs working time — the broader category that includes driving plus all other work activities. The 48-hour WTD limit and the 56-hour 561 driving limit are different ceilings on different things.
You can be compliant with 561 and still breach the WTD. If you drive 56 hours in a week (the 561 weekly driving maximum) but also spent 8 hours doing other work — loading, paperwork, depot time — your total working time was 64 hours. That exceeds the 60-hour WTD single-week maximum. Two separate laws, two separate problems.
This is where self-employed drivers who are meticulous about their tacho records can still end up with a WTD breach they didn't see coming. The tacho records driving time. The WTD covers more than that. The tachograph is not sufficient evidence of WTD compliance on its own.
The records you need to keep
Employed drivers have their working time recorded by their employer — timesheets, tachograph data, depot systems. Self-employed drivers need to maintain their own records showing working time.
In practice, this means: a log of working hours per day, including non-driving time (depot time, administrative work related to the vehicle, waiting time at loading points). Tachograph data covers the driving element. Everything else needs a supplementary record — a notebook, a spreadsheet, an app. The detail doesn't need to be elaborate. Start time, end time, nature of work if different from driving. But it needs to exist and be accurate, and it needs to cover the 17-week rolling period.
DVSA can request working time records from self-employed drivers at a roadside check or a traffic examiner visit. "I don't keep records because I'm self-employed" is not an accepted position.
The agency complexity
A lot of drivers are "self-employed" in the sense that they invoice through an agency or umbrella company rather than being on a PAYE payroll. Whether they're legally self-employed for WTD purposes — or actually workers in employment law terms — depends on the specifics of the arrangement, not the label on the payslip.
If the agency is directing your work (telling you when to be where, for which clients, with no real right to refuse), HMRC and employment tribunals have increasingly found that drivers in this arrangement are "workers" rather than genuinely self-employed. The WTD applies to workers too. And the agency, as the entity directing the work, may have its own WTD obligations towards you.
This is a grey area that's been litigated repeatedly in the last decade. The practical upshot: whether you're self-employed or a worker, the Road Transport (Working Time) Regulations 2005 likely apply to you if you're driving a goods vehicle over 3.5 tonnes. Assuming otherwise is a risk.
What nobody explains at the CPC
Took me fourteen months of self-employment and a conversation with a transport solicitor to understand this properly. The CPC periodic training courses I've done have all covered 561/2006 in some depth. The WTD — especially as it applies to self-employed drivers — gets a mention and a slide and then everyone moves on to the next module.
The result is a significant proportion of self-employed HGV drivers who are genuinely unaware that they're covered, not knowingly non-compliant. That doesn't change the position. But it does suggest the CPC system is not communicating this as effectively as it should be.
The WTD breach consequences for self-employed drivers aren't primarily criminal in the same way as 561 infringements — there's no fixed penalty notice system for WTD in the same direct way. But a Traffic Commissioner can consider WTD compliance as part of the repute assessment for an operator's licence, and a pattern of WTD breaches found during a traffic examiner investigation is not something you want attached to your name in the record.
Keep the records. Track the reference period. Know the 60-hour single-week maximum. These are not complicated obligations. But they need to be actively managed, which means knowing they exist first.
