How the drivers' hours Great Britain domestic rules work for passenger carrying vehicles.

Overview

The GB domestic rules, as contained in the Transport Act 1968 as amended, apply to most vehicles that are exempt from the assimilated drivers’ hours and tachographs rules. Separate rules apply to Northern Ireland.

2.1 Domestic rules exemptions

Private driving is not subject to GB domestic drivers’ hours rules. Private driving doesn’t include:
- driving which is in the course of a drivers’ employment
- driving by a person who drives for the purposes of their own trade or business
The following exemptions apply to drivers who would otherwise be subject to the GB domestic rules:
- if they do not drive for more than 4 hours a day in any week, drivers are exempt from any GB domestic rules for that week
- all working duties must start and finish within a 24-hour period
- a 10-hour period of rest must be taken immediately before the first duty and immediately after the last duty
- rules on driving times and length of working day must be obeyed
- if any working day overlaps into a week in which drivers are not exempt from the rules, then on that day the limits on driving time and length of working day must be obeyed
- an exemption from the rules on driving time and rest applies during any time spent dealing with an emergency
Week Week is the period from 0000 hrs on a Monday to 2400 hrs the following Sunday.

2.2 Domestic driving limits

Driving is defined as being at the controls of a vehicle for the purposes of controlling its movement, whether it is moving or stationary with the engine running, even for a short period of time.

Breaks and continuous driving

Breaks and continuous driving Breaks are for the driver to use exclusively for rest and refreshment so no work of any type can be undertaken during breaks. A break must be a period of at least 30 minutes. It must be a continuous period and cannot be split up.

Minimum break requirements

The number of breaks required depends on the length of the driver’s working day.

In a working day of less than 8 hours 30 minutes duration, a break must be taken at the end of a period of 5 hours 30 minutes of driving, if such a break has not been taken already.

In a working day of 8 hours 30 minutes duration, there are two options: - a break must be taken at the end of a period of 5 hours 30 minutes of driving, if such a break has not been taken already; or - a break is not required if the driver has spent a period of at least 45 minutes not driving and no more than 7 hours and 45 minutes driving.

Whilst a break is not required, a period of rest may be included within the 45 minutes of non-driving time to ensure drivers get the ‘adequate rest’ required under the working time rules to ensure drivers do not pose a risk to themselves or others. More information on adequate rest under working time rules can be found in Annex 2.

In a working day of more than 8 hours 30 minutes, there are two options: - a break must be taken at the end of a period of 5 hours 30 minutes of driving, if such a break has not been taken already; or - if the driver has spent a period of at least 45 minutes not driving and no more than 7 hours and 45 minutes driving, the driver must take a break at the end of 8 hours 30 minutes before they may continue working.

It is recommended that breaks are interspersed across the working day to comply with the requirement under the working time rules that drivers are given ‘adequate rest’.

Regardless of the length of the working day, breaks should not be taken immediately prior to the end of a shift, so there should always be a period of driving or work between the last break and the end of the shift (for example, a driver should not finish their working day with a break). It is important that drivers take breaks during the working day to ensure they are adequately rested to carry out their duties.

Although the GB drivers’ hours rules require minimum break and rest periods, this is just a minimum. Operators need to take into account the requirement under the Working Time Regulations 1998 that drivers are provided with ‘adequate rest’.

Adequate rest is defined as being long and continuous enough to ensure that a driver does not harm themselves, fellow workers or others and that they do not damage their health in the long or short term. This means that when operators are scheduling breaks into a drivers working day they should take into account personal circumstances and the type of driving and duties being carried out by the driver to ensure they are given adequate rest. Adequate rest is a fundamental requirement to ensure drivers remain alert and do not present a danger to other road users or their passengers.

DVSA are responsible for enforcing both the sector specific and general working time requirements. This will be undertaken during operator visits. Examiners will use operator records to establish that the rules, including adequate rest entitlements, have been adhered to.

Failure to ensure that the various regulations are followed could result in enforcement action being taken against both the driver and/or the operator. This could include a prosecution report or a report to the Traffic Commissioner.

Daily driving

In any working day, the maximum amount of driving is 10 hours. The daily driving limit applies to time spent at the wheel, actually driving, and includes any driving done under assimilated or AETR rules.

Day Day is the period between two daily rest periods, or a daily rest period and a weekly rest period.

Daily duty

A driver should work no more than 16 hours between the times of starting and finishing work (including work other than driving and off-duty periods during the working day).

Daily rest periods

A continuous rest of 10 hours must be taken between two consecutive working days. This can be reduced to 8.5 hours up to three times a week.

In addition to the above, employers must also consider the requirement under The Working Time Regulations 1998 that drivers have ‘adequate rest’ (which includes adequate breaks). Adequate rest is defined as being long and continuous enough to ensure that a driver does not harm themselves, fellow workers or others and that they do not damage their health in the long or short term. Taking “adequate rest” means a driver’s personal circumstances need be considered when scheduling duty and rest periods and this may mean that duty and rest periods that comply with the GB domestic are insufficient. See the information in Annex 2 at ‘Driving under the GB domestic drivers’ hours rules (or are an occasional mobile worker)’.

Fortnightly rest periods

In any two consecutive weeks (Monday to Sunday) there must be at least one period of 24 hours off duty.

2.3 Emergencies

The GB domestic rules are relaxed in cases where immediate action is needed to avoid:
- danger to the life or health of people
- serious interruption of essential public services (gas, water, electricity or drainage), of electronic communications or postal services, or in the use of roads
- serious interruption in private or public transport (not including trade disputes) involving carriage of passengers for hire or reward
- serious damage to property
In these cases the time spent dealing with the emergency does not count towards driving or duty time and during the emergency the driver is exempt from the requirement to take breaks or daily rest periods. The fortnightly rest period may be reduced by the amount of time spent on an emergency situation. A situation ceases to be an emergency once it no longer poses any of the above risks.

2.4 Record keeping

There are no record keeping requirements under GB domestic rules for passenger carrying vehicles however drivers should note that on any day when driving is undertaken that is subject to assimilated or AETR rules, they are required to produce on request their driver card and tachograph charts and manual records for any driving/work which was in scope of assimilated/AETR rules for the current day and the previous 28 calendar days.

2.5 Travelling abroad

The GB domestic rules apply only in GB. However, drivers must observe the national rules of the countries in which they travel. The embassies of these countries will be able to assist in establishing the rules that might apply.

2.6 Mixed vehicle types

Where a driver divides their time driving goods carrying vehicles and passenger carrying vehicles under GB domestic rules, then in any working day or week, if they spend most of their time driving passenger vehicles, then the appropriate GB rules for passenger vehicles apply for that day or week.

2.7 Working Time Regulations

Drivers who are subject to the GB domestic rules on drivers’ hours are affected by four provisions under GB Working Time Regulations 1998 (as amended). See Annex 2 (/guidance/drivers-hours-passenger-vehicles/annex-2-working-time-rules) for more details.
