The Complete 2025 DVSA HGV Driver Hours Guide: AETR, Tachographs & Compliance
As of April 21, 2025, major updates to the DVSA HGV driver hours rules have taken effect for UK Heavy Goods Vehicle (HGV) drivers operating internationally. Understanding these changes is critical for compliance, with penalties including £300 fines per infringement and potential licence suspensions.
Key Change: AETR rules now govern UK-international HGV trips, requiring 56-day tachograph records and Smart Tachograph 2 devices by August 2025.
I. Understanding the 2025 HGV Driver Hours Overhaul
The changes stem from the UK's post-Brexit alignment with AETR (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport), replacing previous EU rules for applicable journeys.
What's Changed?
- AETR replaces EU rules for international journeys involving the UK and other AETR nations
- Stricter rest period regulations with lost exemptions (like returning-to-base flexibility)
- New tachograph requirements including 56-day record retention and Smart Tachograph 2
Important: These changes only affect international trips. UK domestic HGV driving rules remain unchanged.
