If you put trucks or coaches on Irish roads, the EU drivers’ hours rules decide how long your drivers can be behind the wheel, when they have to stop, and what records you must keep to prove it. The rules come from Regulation (EC) No 561/2006 and apply across the EU — including every kilometre driven in Ireland. This guide covers the limits, the breaks and rest periods, the tachograph duties that go with them, and how the RSA and the Gardaí enforce it all. Plain English, with a summary table you can stick on the office wall.

Who do the driver hours rules apply to?

The EU drivers’ hours rules apply to most goods vehicles over 3.5 tonnes (including any trailer) and to passenger vehicles built to carry more than nine people including the driver, whether the journey is within Ireland or anywhere else in the EU. A simple rule of thumb: if the vehicle needs a tachograph, the hours rules almost certainly apply.

There is a limited list of exemptions and national derogations — vehicles that cannot exceed 40 km/h, emergency and rescue vehicles, and certain specialised or non-commercial uses, for example. Exemptions are narrower than most people assume, so check the specific wording before relying on one. And the scope is widening, not shrinking: from 1 July 2026, vans of 2.5–3.5 tonnes used for international transport are due to come within the tachograph rules as well. If you run vans across the border or to the Continent, it’s worth planning for that now.

What is the daily driving limit?

The daily driving limit is nine hours between daily rest periods. It can be extended to ten hours, but no more than twice in any one week. Driving time means time at the wheel — loading, paperwork and waiting count as “other work”, not driving.

That distinction matters in practice. The tachograph records each activity under a different mode, and an analyst (or an RSA officer) can see exactly how a day was spent. Drivers who leave the tacho on the wrong mode — recording a break while they’re actually loading, say — create infringements that are entirely avoidable. Make correct mode use part of driver inductions and toolbox talks.

How much can a driver drive in a week and a fortnight?

Weekly driving is capped at 56 hours, and total driving in any two consecutive weeks must not exceed 90 hours. In practice that means a 56-hour week has to be followed by a week with no more than 34 hours of driving.

For these rules, a “week” is fixed: it runs from 00:00 on Monday to 24:00 on Sunday. It is not a rolling seven-day window, so a heavy end to one week and a heavy start to the next can both be legal individually — but the 90-hour fortnight limit still catches the combination. This is one of the most common infringements picked up in tachograph analysis, because nobody spots it without looking at two weeks side by side.

When must a driver take a break?

After 4.5 hours of driving, a driver must take an uninterrupted break of at least 45 minutes, unless they begin a rest period instead. The break can be split into two parts: a first part of at least 15 minutes, followed by a second part of at least 30 minutes.

Two details trip people up. First, the order of a split break is fixed — 15 then 30, never the other way round. Second, a break is a break: the driver may not do any driving or other work during it. Sitting in the cab doing delivery paperwork doesn’t count, and the tachograph record will show it.

What are the daily and weekly rest requirements?

Drivers must take a daily rest of at least 11 hours within each 24-hour period, and a regular weekly rest of at least 45 hours. Daily rest can be reduced to nine hours, but no more than three times between any two weekly rest periods.

Regular daily rest can also be split into two parts — a first period of at least three hours and a second of at least nine hours. On weekly rest, the pattern works in pairs: in any two consecutive weeks a driver must take at least one full 45-hour regular weekly rest; the other can be reduced to as little as 24 hours, with the reduction made up as one block of rest attached to another rest period within the following three weeks.

Where can weekly rest be taken?

Regular weekly rest — 45 hours or more — cannot be taken in the vehicle. It must be taken in suitable accommodation with proper sleeping and sanitary facilities, and where the driver is away from home, the cost of that accommodation generally falls to the employer. A reduced weekly rest of under 45 hours may be taken in the cab, provided the vehicle is stationary and has adequate sleeping facilities.

There is also a return-home provision: operators must organise drivers’ work so that each driver can return to their home, or to the operator’s base in the driver’s home country, to take a weekly rest — broadly at least once every three to four weeks, depending on how reduced weekly rests have been used. For most Irish domestic fleets this takes care of itself; for international work it needs to be planned and documented.

How often must tachograph data be downloaded?

RSA guidance for Irish operators is to download driver card data at least every 21 days and vehicle unit (VU) data at least every 3 months. Downloaded files must then be kept for at least 12 months and produced when an enforcement officer asks for them.

The download deadlines exist because the data is the evidence. A driver card holds a limited history before it starts overwriting itself, and a vehicle that’s away on long-distance work for weeks is the one most likely to be missed by a yard walk with a download key. Gaps in your download record are themselves a red flag at inspection, even if every driver was fully compliant. This is the main reason Irish operators are moving to remote tachograph download — the files collect themselves on schedule, wherever the truck happens to be.

How long must tachograph records be kept?

Tachograph records — driver card files, vehicle unit files, printouts and manual entries — must be kept for at least 12 months and made available to an RSA enforcement officer or a Garda on request. Many operators keep them longer, because the same records are your defence if a question is raised later.

Who enforces driver hours rules in Ireland?

In Ireland, drivers’ hours and tachograph rules are enforced by the Road Safety Authority (RSA) and An Garda Síochána. Enforcement happens two ways: roadside checkpoints — often run jointly — and inspections at operator premises, where downloaded files, schedules and records are examined in detail.

At the roadside, an officer can inspect the tachograph, read the driver card, take printouts and question the driver about recent activity. At a premises inspection, the RSA looks at the bigger picture: whether downloads happened on time, whether infringements were identified and acted on, and whether the operator’s systems show genuine management of driver hours rather than a folder of unread files. Roadworthiness is checked alongside hours — remember that under S.I. No. 348 of 2013 a daily walkaround check is required before a vehicle is first used each day, and maintenance and defect records must be kept for at least two years.

Penalties are not trivial. Drivers’ hours and tachograph offences can lead to fines of up to €5,000 and/or up to six months’ imprisonment per offence — and both the driver and the operator can be held liable for the same infringement. Inspection outcomes can also feed into an operator’s risk rating, and operators with a poor rating can expect to be checked more often. The practical takeaway: it is far cheaper to find and fix infringements yourself, every week, than to have the RSA find them for you.
