Drivers Hours Regulations: A Guide for Operators and Managers

Introduction

In transport and logistics operations, one of the key things that we have to factor in to all our reviews of customer transport & delivery activity is compliance to working time law.

All too often we come across operations where simply through lack of understanding, or not being aware of latest developments in the governing laws, businesses are potentially falling outside of legal compliance. Likewise on the flip side, we also sometimes come across those organisations who are perhaps being too cautious with how they use rules to set their working time capacities for their fleets.

We also find that there can be significant misunderstandings about the role and impact of driver hours regulations versus working time directive regulations. To make sure you stay compliant you must be compliant on both fronts… neither are optional and as you will see below opting out is not an option for LGV drivers.

Below we provide an easy to follow summary outlining the key things you need to know to get your planning solution in order to both drive efficiency and ensure legal compliance and most importantly driver (and other road user) safety.

The Headlines

LGV (Large Goods Vehicle) drivers in the UK are subject to two separate but overlapping sets of rules: EU/UK driver hours law (retained in UK law post-Brexit) and the Road Transport Working Time Directive (WTD). Understanding the distinction between the two is essential for compliance. Driver hours law focuses specifically on driving time, breaks, and rest periods. The WTD adds a broader layer covering total working time, including non-driving duties, and has its own separate provisions for night work.

Both sets of rules apply to drivers of vehicles over 3.5 tonnes GVW engaged in the carriage of goods, with limited exemptions. This document covers the main obligations under both regimes. For complex operational patterns or multi-site operations, many businesses choose to seek input from Transport Consultants or specialist advisers to ensure compliance programmes are correctly structured.

Quick Reference: Key Limits at a Glance

Driving Time (Driver Hours Regulations)

Driver hours law controls how much time a driver can spend actually driving. It does not cover other work activities as those fall under the Working Time Directove.

Daily Driving

A driver must not drive for more than 9 hours in a day. This can be extended to 10 hours on up to two days per week. A ‘day’ in this context runs between two daily rest periods.

Weekly and Fortnightly Driving

• Maximum of 56 hours driving in any single week.
• Maximum of 90 hours driving across any two consecutive weeks.
• These limits exist to prevent excessive fatigue building up over longer periods even when daily limits are technically met.

Breaks (Driver Hours Law)

After a maximum of 4 hours 30 minutes of driving, the driver must take a break of at least 45 minutes. This can be split into two parts; a first break of at least 15 minutes followed by a second break of at least 30 minutes that must be taken in that order.

Importantly, this is a driving break, not a working time break. The driver may not drive during the break, but the WTD has its own separate break obligations based on total hours worked.

Periods of Availability (POA)

A Period of Availability (POA) is time during which the driver is not required to remain with the vehicle but must be available to start or resume driving. Common examples include waiting at a customer site for loading/unloading, or accompanying a vehicle on a ferry or train.

POAs are an important distinction because:

• They do not count as driving time.
• They do not count as working time under the WTD.
• They do count towards the calculation of the working day (i.e. the period between daily rests).
• They cannot be taken as daily or weekly rest.

For a period to qualify as a POA, the driver must know the likely duration in advance, either at the start of the period or at the latest by the beginning of the waiting time. The time and expected duration must be recorded on the tachograph.

Working Time Directive (Road Transport WTD)

The Road Transport WTD applies separately from driver hours law and is enforced by HMRC (not DVSA). It covers all work carried out by the driver: driving; loading and unloading; administrative tasks; vehicle checks; and any other duties. POAs and rest are excluded.

Average Weekly Working Time

Drivers must not average more than 48 hours per week over a 17-week reference period. This is the same headline figure as the general Working Time Regulations, but it cannot be individually opted out of unlike the general WTD, there is no opt-out available for road transport workers.

Maximum Weekly Working Time

In any single week, working time must not exceed 60 hours, regardless of the averaging position.

WTD Breaks

In addition to driving breaks under driver hours law, the WTD requires:

• A break of at least 15 minutes after 6 hours of working time.
• Breaks totalling at least 30 minutes after 9 hours of working time.

Driving breaks can count towards WTD break requirements if taken at the appropriate point. However, the two sets of break rules operate independently, so it is possible to be compliant with one and not the other. For example, you can spend a short amount of time driving, well within the daily driving limits, but your ‘other work’ can push you beyond the maximum working hours, or your combined driving and other work activity may take you beyond the maximum amount of time you can spend before taking a break under the WTD rules.

Rest Requirements

Daily Rest (Driver Hours Law)

Every driver must take a minimum daily rest period within each 24-hour period from the end of the last weekly rest:

• Standard daily rest: 11 consecutive hours.
• Reduced daily rest: 9 consecutive hours. This is permitted up to three times between any two weekly rest periods. No compensatory rest is required.
• Split daily rest: can be split into two periods, the first at least 3 hours, the second at least 9 hours (total 12 hours). This is only permitted in vehicles fitted with a suitable sleeper cab.

Weekly Rest (Driver Hours Law)

A driver must take at least one weekly rest period in every fixed seven-day period:

• Full weekly rest: at least 45 consecutive hours.
• Reduced weekly rest: at least 24 consecutive hours is permitted, but the shortfall (i.e. the difference between the reduced rest taken and 45 hours) must be compensated in full before the end of the third week following the week in question.
• Compensation must be attached to another rest period of at least 9 hours.
• In every two consecutive weeks, at least one full 45-hour weekly rest must be taken.

Night Work & the difference between Driver Hours Law and the WTD

Night work is one of the clearest examples of where the two regulatory regimes operate differently, and it is a common area of confusion. UK Transport Specialists and compliance advisers frequently highlight this distinction as one of the most misunderstood aspects of the rules.

Night Work Under the Road Transport WTD

The Road Transport WTD defines the night period as 00:00 to 04:00 (midnight to 4am). If a driver performs any work during this window, their total working time in that 24-hour period must not exceed 10 hours.

This limit applies to the entire working day that includes night-period work — it is not just the hours worked between midnight and 4am. So a driver who starts a shift at 23:00 and works into the early hours is subject to the 10-hour cap for the whole shift.

Unlike the general WTD night work limit (which allows averaging), the Road Transport WTD 10-hour night limit is an absolute cap, it cannot be averaged or extended. The only exception to this is where as a collective, all drivers under contract have agreed to an extension to this time period. A single individual driver cannot individually opt out of the time directive.

The General WTD Night Definition

The general Working Time Regulations 1998 define the night period more broadly as 23:00 to 06:00 and limit night workers to an average of 8 hours in 24. However, this general regime does not apply to road transport workers who are covered by the Road Transport WTD. The two should not be confused or combined.

It is worth noting that driver hours law contains no specific night work restriction. Daily driving limits (9/10 hours) apply equally regardless of when driving occurs. Night-specific limits come exclusively from the WTD.

Other Work

‘Other work’ under both regimes covers all activities other than driving, breaks, and rest. This includes:

• Loading and unloading.
• Vehicle inspections and safety checks.
• Administration, such as paperwork, delivery notes, tachograph duties.
• Waiting time where the driver is required to be available (distinct from POA…see above).
• Any other work for the employer or a third party.

Other work counts towards the WTD working time total but does not count as driving time under driver hours law. Operators should ensure tachograph and working time records accurately capture other work, as HMRC focus on WTD compliance tends to centre on whether other work is properly recorded, particularly for drivers whose hours are close to the 48-hour average.

Record Keeping & Enforcement

Driver hours law is enforced by DVSA (Driver and Vehicle Standards Agency) and the police, with roadside checks and operator licence reviews. WTD compliance falls to HMRC for enforcement.

Drivers operating within scope are required to use a tachograph (digital or analogue), which records driving, other work, POA, and rest periods automatically or manually. Records must be kept for at least 12 months and made available to enforcement authorities on request.

Logistics Consultants like ours at ASCALi and transport managers working with multi-driver operations often recommend integrated tachograph analysis software to flag potential infringements before they become enforcement issues, particularly for WTD averaging calculations which can be difficult to monitor manually.

In Summary

Staying within the law is paramount for all operators. It is distinctly possible that some may read the above regulations and seek to find ingenious ways to work their way around the system. Period of Availability rules are often used to help those with desires to push the boundaries into territory that could land them in hot water.

Our view is that you should absolutely seek to ensure that you stay within all the rules and put out of mind any considerations around how you can bend the rules but stay legal. Please remember simply ‘staying legal’ does not absolve you of your operator responsibilities should something serious go wrong.

In the work we do at ASCALi as Specialist Vehicle Scheduling Consultants with our clients, we set out our planning models and route scheduling parameters to ensure all legal factors are fully accounted for, and  we urge all other businesses to do likewise.
