ELD vs tachograph: US and EU driver hour compliance compared

A tachograph and an electronic logging device do the same job — they record a driver's driving and rest time — but they are not interchangeable, and the device you must carry depends entirely on where the truck operates: a digital tachograph in the European Union, an ELD in the United States. From 2026-07-01, the European rules expand again, as Smart Tachograph Version 2 becomes mandatory for light commercial vehicles (LCVs) between 2.5 and 3.5 tonnes used in international transport — the biggest tachograph expansion in two decades, confirmed by the European Commission . This guide compares the two systems for European carriers, with a side-by-side table, a jurisdiction decision tree, and clear answers to the question operators actually ask: if my trucks run EU routes and US contracts, what do I need on each side?

For context, the European Commission confirms that, as of 2024, the second-generation smart tachograph is the only version permitted in newly registered heavy goods vehicles in international transport. The US ELD mandate, enforced by the Federal Motor Carrier Safety Administration (FMCSA) since 2017, covers most commercial motor vehicles in interstate commerce.

What is an ELD and where is it legally required?

An ELD, or electronic logging device, is a unit connected to a commercial motor vehicle's engine that automatically records driving time and the driver's Records of Duty Status (RODS). It replaced paper logbooks for most US drivers and exists to enforce the country's Hours of Service (HOS) limits — the federal rules on how long a driver may work and drive before resting.

The ELD is a US instrument. Under the FMCSA mandate, it is required for commercial motor vehicles operating in interstate commerce when the driver is required to keep RODS. Crucially, an ELD is only valid if it is self-certified by its manufacturer and listed on the FMCSA registered ELD list . Carriers must select a device from that list — no other recorder, including a European tachograph, satisfies the rule.

There are limited exemptions from the ELD rule : drivers operating under the short-haul exception (within a 150 air-mile radius and released within 14 hours), those who use paper RODS for no more than 8 days in any 30-day period, drive-away-tow-away operations, and vehicles with engines older than model year 2000. Outside those cases, the device is mandatory. If you are mapping cross-border runs into Canada or Mexico, it helps to check public holiday driving restrictions by country the same way you would in Europe, because rest-day rules shift the clock on both continents.

What is a digital tachograph and why does Europe use it instead of an ELD?

A tachograph is the European equivalent: a device that records driving time, speed, distance, and rest periods, mandated across the EU and tied to a driver's personal smart card. Where the US writes its rules around the ELD, Europe writes its rules around the tachograph, governed by Regulation (EU) 165/2014 for the hardware and Regulation (EC) 561/2006 for the driving and rest limits.

Europe never adopted the ELD because the tachograph predates it by decades and is deeply embedded in EU enforcement. The current generation, the smart tachograph, adds GNSS positioning and — in Version 2 — automatic border-crossing detection and remote interrogation. If you want the mechanics of how the device authenticates the driver card and stores data, see our detailed guide to how digital tachographs work . The short version: the tachograph is the legal record, the driver card is the identity key, and the two together prove compliance at the roadside.

ELD vs tachograph: the key differences at a glance

The two systems diverge on jurisdiction, the hours rules they enforce, how data is downloaded, and how enforcement happens. The table below summarises the practical dimensions a fleet manager needs.

Which hours rules apply — US FMCSA or EU EC 561/2006?

The hours rules follow the road, not the truck's home base. Drive in the US and you are bound by FMCSA Hours of Service. Drive in the EU and you are bound by Regulation (EC) 561/2006.

The US limits, recorded by the ELD, allow a maximum of 11 hours driving after 10 consecutive hours off duty, within a 14-hour on-duty window, with a 30-minute break required after 8 cumulative hours of driving. The EU limits, recorded by the tachograph and summarised by the European Commission , cap daily driving at 9 hours (extendable to 10 hours twice a week), require a 45-minute break after 4.5 hours of driving, and limit weekly driving to 56 hours and fortnightly driving to 90 hours. The IRU's drivers' hours guide is a useful reference for the daily and weekly rest detail.

The practical takeaway: the EU regime is stricter on continuous driving (4.5 hours before a break versus 8 in the US) but the US allows a longer total driving day. A driver cannot "carry over" one jurisdiction's allowance into the other. For EU corridor planning, pairing tachograph limits with real-time GPS tracking for EU fleets helps dispatchers keep a driver inside the 4.5-hour break cycle rather than discovering a breach after the fact.

What happens when a European carrier runs US routes — do they need an ELD?

Yes. If a vehicle operates US interstate routes and the driver must keep RODS, that vehicle needs a registered ELD, regardless of where the carrier is based or what device it runs in Europe. A digital or smart tachograph does not satisfy the FMCSA mandate because it is not on the FMCSA registered list and does not produce the ELD data file format US inspectors accept.

In practice, very few European carriers physically run their own EU-registered trucks on US soil — the Atlantic makes that impractical — but many operate US subsidiaries, lease US-domiciled tractors, or subcontract to US carriers. In every one of those cases, the US-operating equipment carries an ELD and complies with FMCSA HOS, while the EU fleet carries tachographs and complies with EC 561/2006. The two compliance stacks run in parallel; neither device substitutes for the other. A modern dispatch setup helps here: a TMS that integrates tachograph data into one dispatcher view lets a mixed operation manage both record types without juggling separate portals.

Smart Tachograph V2 from July 2026: does it close the gap with ELDs?

The headline change for European operators is the 2026-07-01 expansion. From that date, LCVs over 2.5 tonnes and up to 3.5 tonnes used in international carriage of goods or cabotage for hire or reward fall under EU driving and rest rules and must be fitted with a Smart Tachograph Version 2, as Geotab and other telematics providers confirm . Until now, only vehicles over 3.5 tonnes were caught; the threshold drops to 2.5 tonnes for international work, pulling tens of thousands of vans into scope for the first time.

Smart Tachograph V2 narrows the historic gap with the ELD. It records border crossings automatically, logs loading and unloading events, resists tampering more strongly, and — through its DSRC (Dedicated Short-Range Communication) module — supports remote roadside interrogation, so enforcement officers can read tachograph data wirelessly from a passing vehicle. The European Commission required member states to deploy remote detection equipment from 2024, and tolerance periods for non-compliant heavy vehicles ended in 2025. In several respects, the V2 tachograph is now more capable than a standard ELD, which still relies on the driver presenting data on demand. The functional convergence does not make the devices interchangeable — the legal frameworks remain separate — but it does mean a European fleet manager gets richer, more enforceable data than ever before. Note: UK-only and own-account journeys remain exempt from the LCV requirement.

A jurisdiction decision tree: which device do I actually need?

Use these three branches to decide what each vehicle must carry.

EU routes only

Fit a type-approved smart tachograph. Heavy goods vehicles and coaches need one already; from 2026-07-01, LCVs between 2.5 and 3.5 tonnes on international or cabotage work need Smart Tachograph V2. Comply with EC 561/2006 hours, download the driver card every 28 days and the vehicle unit every 90 days. No ELD is required or accepted. Keep live EU diesel prices in view when planning refuel and rest stops along the 4.5-hour break cycle.

US routes only

Fit an FMCSA-registered, self-certified ELD. Comply with FMCSA Hours of Service (11-hour drive limit, 14-hour window, 30-minute break). Ensure the driver can transfer or display the previous 8 days of RODS at roadside. No tachograph is required or accepted.

Both EU routes and US contracts

Run both compliance stacks in parallel. EU-operating vehicles carry tachographs and follow EC 561/2006; US-operating vehicles carry ELDs and follow FMCSA HOS. There is no single device that covers both, and no rule that lets one substitute for the other. Manage the two record types centrally rather than per-region, and train drivers on whichever regime applies to the leg they are driving.

Can telematics software supplement tachograph and ELD compliance?

Telematics does not replace the legal device on either side — the tachograph and the ELD remain the official records — but it makes both far easier to manage. Software can pull tachograph download files on schedule, flag an approaching 28-day driver-card deadline, alert a dispatcher before a driver breaches the 4.5-hour break rule, and store records for audit. On the US side, ELDs are already cloud-connected by design, so the carrier sees RODS continuously.

For European drivers, Logifie's Driver Assistant app helps track hours and rest cycles digitally so a driver knows where they stand against EC 561/2006 limits before an enforcement officer does. The goal is the same on both continents: the device proves compliance, but software prevents the breach in the first place.

Frequently asked questions

Is there an ELD requirement in Europe?

No. Europe does not use the ELD and has no ELD mandate. The EU enforces driving and rest rules through the digital and smart tachograph under Regulation (EU) 165/2014, recording compliance with Regulation (EC) 561/2006. An ELD is neither required nor recognised for EU operations.

Do ELDs work in Europe?

An ELD is a US-certified device and is not a valid compliance record in the EU. Even if the hardware physically functions, EU enforcement officers check the tachograph and the driver card, not an ELD output. For European routes you need a type-approved tachograph, not an ELD.

What is the difference between a tachograph and an ELD?

Both record driving and rest time, but they belong to different legal systems. The tachograph is the EU device under EC 561/2006, with a 9-hour daily driving limit and a 45-minute break after 4.5 hours. The ELD is the US device under FMCSA Hours of Service, with an 11-hour driving limit and a 14-hour duty window. The hardware standards, data formats, and download rules differ, and neither device is accepted in the other jurisdiction.

Do UK trucks need an ELD?

No. The UK uses tachographs, not ELDs. After Brexit, the UK retained EU drivers' hours rules in domestic law, with some GB domestic rules layered on top, and enforcement is carried out by the DVSA (Driver and Vehicle Standards Agency). UK trucks running in the EU need a smart tachograph, the same as EU operators, and would only need an ELD if a UK-owned vehicle were operated on US interstate routes.

Can a tachograph replace an ELD for US operations?

No. The FMCSA requires a device that is self-certified and on its registered ELD list, producing a specific ELD data file. A European tachograph is not on that list and does not output the required format, so it cannot substitute for an ELD. A vehicle on US interstate routes must carry a registered ELD.

What is Smart Tachograph V2 and when is it required?

Smart Tachograph V2 (also called G2V2) is the second-generation smart tachograph. It adds automatic border-crossing recording, loading and unloading logs, stronger anti-tampering, and DSRC remote interrogation. It is mandatory in newly registered heavy goods vehicles in international transport, was required by retrofit for international heavy vehicles in 2025, and from 2026-07-01 becomes mandatory for LCVs between 2.5 and 3.5 tonnes used in international or cabotage transport for hire or reward.

What are the download frequency rules for a tachograph vs an ELD?

In the EU, the driver card must be downloaded at least every 28 days and the vehicle unit at least every 90 days, and a driver must carry records for the current day plus the previous 28 days. In the US, the ELD transmits data continuously, the carrier retains RODS (generally for six months), and the driver must be able to transfer or display the previous 8 days of logs at the roadside. There is no fixed 28- or 90-day download cycle for the ELD.
