How many hours can a lorry driver work in the UK?

If you run HGV vehicles in the UK, the short answer is that a lorry driver cannot simply work until the shift is finished. In most haulage and logistics operations, the legal limits come from EU drivers’ hours rules, as retained in Great Britain, plus Working Time rules for mobile workers. That usually means a maximum of 9 hours’ driving in a day, extendable to 10 hours twice in a week, 56 hours’ driving in a week, and 90 hours across any two consecutive weeks, with strict break and rest requirements around that.

The detail matters because operators do not manage only driving time. We also have to manage other work, availability, daily rest, weekly rest, Tachograph records and the difference between the rules that apply to HGV work and the rules that apply to domestic operations. If the wrong regime is used, a legal-looking schedule can still become non-compliant very quickly.

Which rules apply to a lorry driver?

The first question is not how many hours can a lorry driver work, but which legal regime applies to that journey and that vehicle.

For most HGV operators in the UK, the main rules are the EU drivers’ hours rules, as retained in GB law. These generally apply to goods vehicles over 3.5 tonnes used for carriage by road. If we are running normal haulage, pallet network, trunking, general distribution or most for-hire or own-account HGV work, this is usually the starting point.

Alongside those rules, we also need to consider the Road Transport Working Time rules for mobile workers. These are separate from drivers’ hours rules. A driver can be within driving limits but still breach working time limits if total working time is not controlled properly.

Then there are the GB domestic drivers’ hours rules. These apply where the EU rules do not. That can include certain operations involving smaller vehicles, specialist use cases, or work that falls outside the scope of the EU regime. The domestic rules are different and usually less familiar to HGV operators, which is exactly why teams can get caught out by them.

Why does this matter first? Because the limits, records and compliance checks change depending on the regime. Under EU rules, we are looking at daily and weekly driving caps, 4.5 hour break triggers, daily and weekly rest, Tachograph use and manual entries. Under domestic rules, the focus is different. Under Working Time rules, we are looking at working time averages, night work limits where relevant, and whether periods count as work, availability or rest.

There are also exemptions and special cases. Some vehicles, routes and activities can fall outside the full EU rules or qualify for specific derogations. That does not mean there are no rules. It means we need to identify the correct one before scheduling the work.

For operators with mixed fleets, this is where compliance becomes operational rather than theoretical. A business might run HGV trunking under EU rules, local support vehicles under domestic rules, and drivers who switch between different duties in the same week. If we do not classify that correctly, our planning, Tachograph review and payroll assumptions can all drift away from what the law requires.

As a practical rule, we recommend deciding the applicable regime before the job goes on the board, not after an infringement appears. That means checking vehicle type, gross vehicle weight, journey purpose, route pattern and whether the activity is in scope for EU drivers’ hours. It also means making sure traffic office staff and planners understand that “working hours” and “driving hours” are not the same thing.

If you want a wider operational view of where these frameworks overlap, our guide to UK driver hours rules made practical for fleet operators sets out the main compliance picture for day-to-day fleet use.

What are the main daily and weekly driving limits?

For most HGV work under EU drivers’ hours rules, the core driving limits are straightforward once we separate them from duty time.

Daily driving is normally limited to 9 hours. This can be extended to 10 hours, but only twice in a fixed week. A fixed week runs from 00:00 on Monday to 24:00 on Sunday.

Weekly driving is capped at 56 hours in that fixed week.

Fortnightly driving is capped at 90 hours in any two consecutive fixed weeks. This is one of the limits that often catches operators out. A driver could be legal in week one and legal in week two when each week is viewed on its own, but still exceed the 90 hour fortnightly cap when both are added together.

For example, if a driver records 56 hours in one week, they can only drive 34 hours in the following week. If they drive 45 hours in week one, they can drive up to 45 in week two. This is why weekly planning has to look ahead, not just close out the current week.

It is also important to separate driving from shift length. A driver may be on duty for much longer than 9 or 10 hours because loading, vehicle checks, waiting, paperwork and other tasks are not all driving. The legal issue is how each period is classified and whether the day still includes the required breaks and rest.

Working Time rules add another layer. For mobile workers, average weekly working time must not exceed 48 hours over the relevant reference period, although total working time can reach 60 hours in a single week if the average remains within the limit. This is not a driving limit, but it directly affects how many duties we can assign.

Night work can also trigger extra control. If a mobile worker performs night work, working time must not exceed 10 hours in any 24 hour period, unless there is a relevant workforce or collective agreement that allows otherwise. Operators should check exactly how night time is defined for their operation, because the applicable period can depend on the rules in force and the working arrangements used.

The practical point is that legal scheduling is never just “How many hours can they be out?” We need to test the shift against daily driving, weekly driving, fortnightly driving and working time. If any one of those is missed, the schedule is not compliant.

For a closer look at the week-level limits, see our article on how many hours an HGV driver can work in a week.

What breaks and rest periods must a driver take?

Under EU drivers’ hours rules, a driver must not drive for more than 4.5 hours without taking a qualifying break. The standard requirement is 45 minutes of break after no more than 4.5 hours of driving.

That 45 minute break can be taken in one block, or split into 15 minutes followed by 30 minutes, in that order. Other split patterns do not meet the rule. A common mistake is assuming any combination adding up to 45 minutes is acceptable. It is not.

Break is not the same as rest. A break interrupts driving for the purpose of road safety and fatigue control. Daily rest is the period that allows the driver to recover between duties.

The standard daily rest requirement is at least 11 hours. This can be taken as one continuous period, or split into 3 hours followed by 9 hours, for a total of 12 hours. Drivers may also take reduced daily rest of at least 9 hours, but not less than 9. In most standard operations, reduced daily rest can be used up to three times between weekly rest periods.

Weekly rest also has to be built into the schedule. A regular weekly rest is at least 45 hours. A reduced weekly rest is at least 24 hours, but any reduction below 45 hours has to be compensated by an equivalent period of rest attached to another rest period before the end of the third week following the week in question.

There are also timing rules around when weekly rest must start. In broad terms, a driver must begin a weekly rest period after no more than six 24 hour periods from the end of the previous weekly rest. This means we cannot just keep extending working patterns because the route still looks feasible on paper.

Operators should also remember the cab accommodation rule. Regular weekly rest cannot be taken in the vehicle. If a driver takes a regular weekly rest away from base, suitable accommodation with appropriate sleeping and sanitary facilities must be provided by the employer.

In legal scheduling, breaks and rest should be planned before the run starts, not treated as something the driver will “fit in”. This is especially important where loading slots, port movements, RDC queues or timed deliveries create pressure on the day. A route that only works if the driver skips or delays a required break is not a compliant route.

This is one reason many fleets move away from manual spreadsheets. Exception alerts around remaining driving time, break due times and rest requirements are much easier to manage when Tachograph data and vehicle activity are visible together. Our guide on tracking driver hours across a fleet covers the routines that make that practical.

What counts as other work, availability and rest?

A lot of compliance problems come from recording the right activity under the wrong mode. Driving is only one part of the day. To manage driver hours properly, we need to distinguish between driving, other work, periods of availability and rest or break.

Driving is exactly that, time spent driving a vehicle in scope.

Other work includes loading and unloading, vehicle checks, cleaning, maintenance, paperwork, route planning, attending depots, and any work for the same or another employer. If a driver spends an hour helping load at a customer site, that is not rest. If they complete defect reporting or daily walkaround checks, that is not rest either.

Periods of availability are different. These are times when the driver is not required to remain at their workstation but must be available to answer a call to start or resume driving or other work. Typical examples can include waiting time where the likely duration is known in advance, or time spent accompanying a vehicle on a ferry or train in the right circumstances. The key point is that the driver is available, but not actively working.

Rest and break are protected categories. They are not general downtime and cannot be used to cover waiting time if the driver is still effectively working or does not know how long the interruption will last.

This matters for both legal records and real scheduling. If loading time is wrongly marked as break, the driver may appear compliant on paper while actually missing the break needed after 4.5 hours of driving. If long queueing time is wrongly treated as rest, the daily rest record may be false. If all non-driving time is lumped together, Working Time calculations become unreliable.

Tachograph mode selection and manual entries are therefore operational controls, not admin detail. Drivers need to know when to switch mode, and office staff need to review records for obvious mismatches between the route, the job and the activity shown.

In practice, we also compare Tachograph data with other sources. GPS movement, geofence events, depot arrival times, customer dwell time, walkaround checks and dispatch records all help us judge whether the recorded activity matches what actually happened. On mixed fleets, connected data can also show whether a vehicle was stationary at a site while the driver remained on other work rather than break.

How should operators monitor driver hours in practice?

Good compliance comes from routine, not from end-of-month paperwork. The operators who stay on top of driver hours usually follow the same pattern every day and every week.

First, we need current data. That means regular vehicle unit and driver card downloads, with a schedule that does not leave gaps. Remote Tachograph downloads reduce the risk of missed deadlines and let the transport office review activity while the work is still recent enough to investigate properly.

Second, we need daily exception checks. At a minimum, that should include upcoming break requirements, remaining daily driving, reduced rest use, weekly driving accumulation and fortnightly totals. If a planner can only see today’s route and not the previous 13 days, the 90 hour fortnightly cap will be missed sooner or later.

Third, we need a process for infringements and anomalies. Not every exception is the same. Some are clear breaches. Some are data issues, missed manual entries or card handling problems. Some point to a planning failure, such as repeated late break patterns on the same route. The point is to investigate each exception, record the outcome and take corrective action where needed.

Fourth, we need reporting that planners and managers will actually use. A compliance report that sits in a folder is not much use. We need views that show who is close to limits, which depots are generating the most infringements, which routes create repeated pressure, and which drivers need retraining on mode use or manual entries.

This is where combining systems matters. When vehicle tracking, Tachograph data and driver reporting sit in separate tools, teams spend time reconciling spreadsheets instead of managing risk. With Fleetalyse, we focus on putting those operational views in one place, so transport teams can see movement, driver activity and compliance trends together rather than chasing them across different logins.

For many fleets, the most effective routine looks like this:

Review previous day infringements each morning.

Check drivers approaching weekly or fortnightly limits before allocating new work.

Confirm missing downloads, card issues and unassigned mileage.

Investigate repeated break or rest problems by route, customer site or depot.

Keep evidence of debriefs, retraining and corrective action.

Use trend reporting, not only single incidents, to spot where planning assumptions are unrealistic.

Connected fleet data makes these checks easier to action. Remote downloads show the records. GPS location and timing show where the pressure points are. Smart dashcams can add context where driver behaviour or road conditions are part of the picture. If you are also using Fleetalyse-ready trackers or unlocked Teltonika hardware, we can bring more of that operational picture together in one platform, rather than splitting compliance from fleet visibility.

For operators tightening up their process, our article on one platform for tracking, Tachograph and driver hours shows how that joined-up workflow helps reduce blind spots.

The legal answer to how many hours a lorry driver can work in the UK is never just one number. For most HGV operations, we have to manage daily driving, weekly driving, fortnightly driving, breaks, daily rest, weekly rest and Working Time limits all at once. The safest fleets are the ones that identify the correct rules first, record activity properly, and monitor exceptions while there is still time to fix the plan.
