Daily rest explained: regular, reduced and split

The three types of daily rest at a glance

Under the assimilated drivers’ hours rules (the rules previously called “EU rules”, set out in Regulation (EC) 561/2006), a driver of an in-scope HGV or PSV must take a daily rest period within every 24-hour period, measured from the end of their last rest. There are three ways to take it: a regular daily rest of at least 11 continuous hours; a split daily rest of at least 12 hours in total, taken as a block of at least 3 hours plus a block of at least 9 hours; or a reduced daily rest of at least 9 but less than 11 hours, allowed up to three times between any two weekly rests.

• Regular daily rest - at least 11 hours in one unbroken block.
• Split daily rest - at least 12 hours total, taken as one block of at least 3 hours plus one block of at least 9 hours. This counts as a regular rest, not a reduction.
• Reduced daily rest - at least 9 hours but under 11. Allowed no more than three times between any two weekly rest periods, with no requirement to pay the time back.

These limits are identical for goods and passenger vehicles and come from the same regulation. For the wider picture (driving limits, breaks and weekly rest), see the pillar guide.

Who this guide applies to

This article covers daily rest under the assimilated drivers’ hours rules (previously the EU rules) and the closely aligned AETR rules for international work. In practice, that means most goods vehicles over 3.5 tonnes (including any trailer) and most passenger vehicles constructed or adapted to carry more than nine people including the driver.

If the vehicle or journey is exempt from the assimilated rules, a different rulebook applies  (GB domestic, Northern Ireland domestic, AETR, or a specific exemption)  and the figures below may not. Work out which set applies before using this guide.

What “daily rest” actually means

A rest period is an uninterrupted block of time in which the driver is free to dispose of their own time. If the driver is doing any kind of work, or is restricted in a way that stops them disposing of that time, it is not rest.

In practice, a driver is not resting while they are:

• loading or unloading, or supervising it
• fuelling, or carrying out walk-around checks
• doing paperwork or dealing with the office
• attending training they are required by their employer to attend
• working a second job, paid or unpaid
• kept on call in a way that limits where they can be or what they can do

The tachograph mode is the record, but it has to match reality. Putting the card to rest mode does not turn a period of other work, duty or controlled on-call into rest and at a roadside check or audit, the underlying facts are what count. (GOV.UK guidance)

How the 24-hour clock works

The 24-hour window runs from the end of the previous daily or weekly rest, not from midnight, and not from clock-on. Once a driver finishes a qualifying rest and starts the next duty, they must have completed their next daily rest within 24 hours of that point.

Worked example: a driver who comes off a weekly rest and starts work at 06:00 on Monday must, by 06:00 on Tuesday, have completed one of: an 11-hour regular rest, a 3-plus-9 split rest (12 hours). Or, if still entitled,  a 9-hour reduced rest.

Whatever rest you take eats into the window. From that 06:00 start, an 11-hour rest means wrapping the shift up by 19:00; a 9-hour reduced rest buys until 21:00. That extra two hours is the whole point of a reduction, but it does not switch off the separate driving, working-time, break and night-work limits, which apply on their own terms.

Regular daily rest: 11 hours

The standard daily rest is 11 continuous hours. Take it and you have up to 13 hours in the 24-hour window for driving, other work, breaks and periods of availability combined. It is the rest the rules are built around, and the one that keeps a driver clear of the separate limit on reduced rests.

• 11 hours exactly counts. 10 hours 59 minutes does not. If it is at least 9 hours, it falls back to being a reduced daily rest.
• It uses none of the three reductions. Sticking to 11 hours keeps all three reduced-rest allowances in reserve.
• A daily rest can be extended into a weekly rest. Useful when a shift ends close to the point a weekly rest is due.
• Legal is not the same as well-rested. A 13-hour spread can still be a tired driver. Early starts, night work, intensive routes and heavy handball drive fatigue whatever the record allows.

Split daily rest: 3 + 9 = 12 hours

A regular daily rest can be taken in two separate blocks rather than one. The first block must be at least 3 hours and the second at least 9 hours, and both must be uninterrupted.

• It still counts as a regular daily rest. Splitting does not use up one of your reduced-rest allowances.
• The total is 12 hours, not 11. Choosing to split adds an hour to the minimum, so it leaves less of the 24-hour window for work than a straight 11-hour rest.
• The order matters. A 2-hour block followed by 10 hours is not a valid split, as the first part is under 3 hours. A 10-hour block followed by 3 hours is not valid either. The block that completes the rest must be at least 9 hours.
• It only counts if the driver was genuinely free. Waiting time at a delivery point is rest only if the driver could truly dispose of the time, not if they were tied to the vehicle.

Common misunderstanding: a split daily rest is 12 hours, not 11. Drivers and planners often assume that splitting simply rearranges the 11 hours. It does not. The moment you split, the minimum becomes 12.

Reduced daily rest: 9 hours

Daily rest can be cut to as little as 9 continuous hours, but only three times between any two weekly rest periods. A 9-hour rest gives up to 15 hours in the 24-hour window. The longest a single-manned driver’s working day can legally spread.

• 9 hours exactly is valid. 8 hours 59 minutes is not a rest period at all under these rules.
• No payback is required. Unlike a reduced weekly rest, a reduced daily rest does not have to be compensated later. The hours are simply gone. There is nothing to make up.
• The count resets at weekly rest, not on Monday. The three reductions run between one weekly rest and the next, so a driver working irregular days needs to track them against their actual rest pattern, not the calendar week.
• A fourth reduction is normally an infringement. Once three reduced rests have been used, the next daily rest before a weekly rest must be a full regular rest.

This is a classic source of operator risk: each individual day can look fine while the pattern between weekly rests quietly breaches the three-reduction limit. Good analysis checks both the length of each duty period, rest period and the running count of reductions since the last weekly rest.

Can daily rest be taken in the cab?

Yes. Any daily rest, regular, split or reduced, may be taken in the vehicle, provided the vehicle is stationary and has suitable sleeping facilities: a proper bunk or bed designed for sleeping on. If there is no bunk, the driver needs other accommodation, such as a hotel or guest house, and the employer meets the cost.

Two distinctions are worth holding onto. First, a regular weekly rest can never be taken in the vehicle but daily rest can. Second, daily rest is not a break: a co-driver may take a 45-minute break while the vehicle is moving, but daily rest only counts when the vehicle is stationary and the driver is free to dispose of their time.

Daily rest with two drivers (multi-manning)

On a genuinely multi-manned shift, each driver must take a daily rest of at least 9 hours, but they get a 30-hour window to do it in rather than 24. For the first hour of the shift the second driver is optional; after that, a second driver must be present for the concession to apply.

The catch: a 9-hour rest is a reduced daily rest, so it counts towards the limit of three reductions between weekly rests. To keep the rest “regular” and avoid using up an allowance, the crew can instead take 11 hours, or a proper 3-plus-9 split, within the 30 hours.

Interrupting daily rest for a ferry or train

A regular daily rest, and only a regular one, can be interrupted when the driver is accompanying the vehicle on a ferry or train. A reduced daily rest cannot be interrupted this way. (Regulation 561/2006, Article 9)

The conditions are:

• No more than two interruptions, totalling no more than one hour. For example, driving on at the start, off at the end, plus customs formalities.
• The driver must have access to a sleeper cabin, bunk or couchette.
• The rest must still add up to the full 11 hours (or 12 if split) and, for a single-manned driver, be completed within the 24-hour window.

Unforeseen events are not a planning tool

There is a narrow safety valve. Under Article 12 of the regulation, a driver may depart from the daily rest and other requirements, but only as far as needed to reach a safe stopping place and protect the safety of people, the vehicle or its load, and only where road safety is not put at risk.

It exists for genuinely unforeseen disruption: a collision ahead, severe weather, a breakdown, a cancelled ferry. The driver must record the reason by hand, on a printout, a temporary sheet or the duty roster, by the time they reach the stopping place at the latest.

What it is not is a way to rescue an over-ambitious schedule. Repeated “unforeseen events” in the data are a red flag to DVSA that the work was never realistically planned to comply in the first place.

Common mistakes to avoid

• Treating a split rest as 11 hours. It is 12 - splitting costs an hour.
• Counting a 9-hour rest as a regular rest. It is a reduced rest and uses one of the three.
• Going past three reduced rests between weekly rests  or forgetting the count resets at weekly rest, not on a Monday.
• Calling a period “split rest” when it is not a block of at least 3 hours plus a block of at least 9.
• Counting waiting time or availability as rest when the driver was not genuinely free.
• Using the 30-hour multi-manning window when the crew conditions were not actually met.
• Treating the 24 hours as a calendar day rather than a rolling window from the end of the last rest.
• Resting in a moving cab, or leaning on “unforeseen events” to paper over a planning failure.

A quick operator checklist

1. Find the end of the driver’s last daily or weekly rest. That is where the clock starts.
2. Work out the deadline: 24 hours from that point, or 30 hours for compliant multi-manning.
3. Decide which rest the plan uses, regular (11h), split (3+9), or reduced (9h).
4. If it is reduced, check how many reductions the driver has already used since their last weekly rest.
5. If it is split, confirm the first block is at least 3 hours and the closing block at least 9.
6. Check driving time, working time, breaks and night work as separate tests. A legal daily rest does not make the whole shift legal.
7. Make sure the tachograph record actually supports what happened. (GOV.UK: tachograph rules)

Getting daily rest right across a fleet

Daily rest is simple in principle and easy to slip on in practice; a split logged as 11 hours, a fourth reduction that should have been an 11-hour night, a rest that fell a few minutes short of nine, a yard movement that quietly interrupted an off-duty block. These are exactly the infringements that proper tachograph analysis catches before they become a pattern. Identifying them and putting the evidence in front of your transport manager is what Tacho Agent does.
