Daily rest gets most of the attention in drivers’ hours discussions, but weekly rest is where enforcement finds patterns. A driver who never quite gets a proper weekly rest is one of the clearest signals of an operator organising work illegally, and DVSA’s assimilated rules guidance is precise about how the weekly rest must work.
A driver must start a weekly rest no later than the end of six consecutive 24-hour periods from the end of the previous weekly rest. Weekly rest is a period during which the driver may freely dispose of their time, and it comes in two forms. A regular weekly rest is at least 45 continuous hours. A reduced weekly rest is at least 24 but less than 45 continuous hours, and a reduction has to be paid back.
Two clocks run at once, which is where people get confused. The working week starts at the end of one weekly rest and finishes when the next begins, and it does not need to align with the calendar. Separately, the fixed week runs from 00:00 on Monday to 24:00 on Sunday, and the fixed week is what the fortnightly minimum is measured against.
In any two consecutive fixed weeks, a driver must take at least either two regular weekly rests, or one regular weekly rest and one reduced weekly rest. More rest is always allowed; less is not.
A weekly rest that straddles two fixed weeks counts in either week, but not both. There is one useful refinement: if a rest of at least 69 hours starts in one fixed week and ends in the next, it can count as two back-to-back weekly rests, in effect a 45-hour rest followed by 24 hours, provided no more than 144 hours (six times 24) has elapsed since the end of the previous weekly rest.
A reduced weekly rest must be compensated by an equivalent period of rest, taken in one block, before the end of the third week following the week in which the reduction happened. The compensation must be attached to a rest period of at least 9 hours, so in practice it bolts onto a daily or weekly rest. DVSA’s worked example makes the mechanics concrete: a driver who cuts a weekly rest to 33 hours owes 12 hours, and that 12 must be attached to another rest of at least 9 hours before the end of week four. It cannot be split into smaller pieces scattered across the month.
That last point is the one trip-up planners miss: compensation is one block, attached to a qualifying rest, inside a hard window. “He’s had quiet weekends since” is not compensation.
Rest means the driver freely disposes of their time. Work in any other employment, and volunteering where there is an obligation to undertake duties, counts as duty, not rest. The guidance names the traps: self-employed work, community service, retained firefighting, volunteer police work, RNLI and mountain rescue callouts, and Driver CPC training requested by the employer. CPC training can sit inside a rest period only if the driver attends genuinely voluntarily, not at the employer’s instigation.
There is a narrow concession for reservists and cadet force instructors, suspending the weekly rest requirement at the end of the six 24-hour periods when training starts, with a regular weekly rest due no later than the end of the sixth day after training, and caps on how many sessions qualify. No equivalent concession exists for retained firefighters or other voluntary emergency work.
Daily rest may be taken in the vehicle, but only if it has suitable sleeping facilities, meaning a bunk or bed designed for sleeping, and the vehicle must be stationary for the whole period, including on multi-manned journeys. No bunk means other arrangements: the guidance lists hotels, hostels, guest houses, chalets, static caravans or rental accommodation. The operator’s duty to organise work so rest can be taken properly follows from this; sending a driver out with no realistic place to rest is the operator’s infringement, not just the driver’s.
Drivers on international carriage of goods under the assimilated rules may take two consecutive reduced weekly rests, provided that in any four consecutive fixed weeks they take at least four weekly rests, at least two of them regular. The derogation is for time spent outside both the UK and the driver’s country of residence, and ferry or train interruptions are permitted within it if the whole rest is taken outside the employer’s country of establishment and the driver’s residence country. When two reduced rests run consecutively, the compensation for both must come first, attached to the next weekly rest, which must be a regular one.
AETR journeys do not get this concession, because the AETR agreement has not been aligned with the assimilated regulation: drivers on AETR work keep to the standard fortnightly pattern.
Operators must also organise international work so that within each four-week period the driver can return to their normal operating centre or home to spend a regular weekly rest there, arriving before the rest begins. Planning a rota that strands a driver abroad on their 45 is a planning infringement.
Weekly rest failures rarely start with a driver deciding to skip rest. They start with a plan that was never legal: six days of work with a 24-hour gap sold as a weekend, compensation nobody tracked, a trunk that overruns every Friday. Because the rules run on fixed weeks and hard deadlines, the traffic office either manages them deliberately or infringes them systematically. The records DVSA pulls at a roadside stop or investigation show which one you are.
