Two regimes, one obligation
British operators work under two sets of drivers hours rules. Most goods vehicles over 3.5 tonnes, and most coach work, run under the retained EU regime (Regulation 561/2006) with tachographs recording every minute. Smaller vehicles and certain exempt operations run under the GB domestic rules, recorded more simply but no less enforceable. Many mixed fleets have drivers under both in the same week, and some duties combine them in a single day.
Whichever regime applies, the obligation on the operator is identical: know which rules cover each duty, schedule work so the rules can be kept, monitor what actually happened, and act on what you find. In 25 years of DVSA investigations and Traffic Commissioner hearings we have seen far more licences damaged by unmanaged drivers hours than by deliberate cheating. The rules themselves are learnable in an afternoon; it is the daily management, and the instructions drivers carry, that separates compliant fleets from the rest.
The EU limits: driving, breaks and the 4.5 hour rule
The EU drivers hours rules set limits that every professional driver should be able to recite. Daily driving is capped at 9 hours, extendable to 10 hours no more than twice in a week. Weekly driving must not exceed 56 hours, and driving across any two consecutive weeks must not exceed 90 hours.
The break requirement is the one that catches most drivers: after 4.5 hours of accumulated driving, a break of at least 45 minutes must be taken, during which the driver does no driving and no other work. The 45 minutes can be split into a break of at least 15 minutes followed by one of at least 30 minutes, in that order, within the same 4.5 hour driving period. Drivers call this the 4.5 hour rule, and misunderstanding the split (30 then 15 does not count) remains one of the most common infringements we see in tachograph analysis. A driver who understands why the order matters, not just that it matters, stops making the error.
Rest: daily, weekly and the reductions
Driving limits get the attention, but rest requirements generate just as many infringements. Under the EU drivers hours rules a driver needs a daily rest of 11 hours in each 24 hour period, reducible to 9 hours no more than three times between weekly rests. Split daily rest is allowed as 3 hours plus 9 hours in that order. Each week a driver needs a weekly rest of 45 hours, which can be reduced to as little as 24 hours in alternate weeks, with the reduction compensated by an equivalent block of rest attached to another rest period within the following three weeks.
A regular weekly rest cannot be taken in the vehicle. The compensation rule is the one that quietly trips up planners: the reduced weekend is remembered, the payback is not, and three weeks later an infringement crystallises that nobody noticed at the time. Scheduling software helps, but drivers still make the final decision at the end of a long day, which is why the rest rules need to be in their hands in writing, in language that survives a layby at midnight.
GB domestic rules and working time
Drivers outside the EU regime are not outside the law. The GB domestic drivers hours rules cap driving at 10 hours in a day and duty at 11 hours for goods vehicles, with their own record keeping requirements, and separate provisions apply to domestic passenger work. Van fleets frequently assume none of this applies to them; much of it does, and DVSA checks it.
On top of both regimes sits working time law. For mobile workers under the road transport rules this means an average 48 hour working week over the reference period, a 60 hour cap on any single week, night work limits and mandatory in-work breaks. Hours spent on other work, loading included, count even when driving time looks legal. The interaction between tachograph rules and working time is where even experienced transport offices make mistakes, so our handbooks state the combined effect for your specific operation rather than reprinting three sets of legislation and hoping drivers reconcile them.
The infringements that actually occur
Two and a half decades of tachograph analysis reports show the same offenders in every fleet:
- Breaks taken late, short or split the wrong way round under the 4.5 hour rule
- Daily rest reduced more than three times between weekly rests
- Missed weekly rest compensation
- Driving on into the tenth hour more than twice a week
- Card not inserted, mode switch left on rest while working, or manual entries missing
- Insufficient daily rest caused by early starts after late finishes, a planning failure rather than a driver one
Most of these are errors of understanding or scheduling, not intent, which is precisely why enforcement treats repeat patterns so seriously: they show an operator that is not managing. An infringement followed by a documented debrief and a falling trend reads as a system working. The same infringement repeating monthly with no paperwork reads as a licence risk, and at a public inquiry it will be presented as exactly that.
How a handbook keeps drivers legal
Tachograph analysis tells you about infringements after they exist. The cheaper intervention is before: drivers who genuinely understand the drivers hours rules commit a fraction of the infringements, and the handbook is where that understanding is built and evidenced. Ours set out the limits in tables a driver can check in the cab, the break and rest rules in plain English with worked examples, the mode switch and manual entry procedures for your tachograph units, and exactly what to do when traffic, queues at an RDC or a breakdown put a legal finish out of reach.
Just as importantly, the handbook records that every driver received and accepted those instructions, which transforms your position in any investigation. When DVSA or a Traffic Commissioner asks how your drivers know the drivers hours rules, the answer is a signed, version-controlled document plus debrief records showing the loop closes. We build that package for fleets of every size, and we have watched it change the outcome of hearings. Hours compliance is not a knowledge problem in this industry; it is a communication and evidence problem, and both are solvable.
