# Length Restrictions for Road Freight Vehicles

*Last updated: 2026-06-25*

> Compliant route planning for a long-haul truck starts with knowing the maximum permitted length for every road segment along the way.

Compliant route planning for a long-haul truck starts with knowing the maximum permitted length for every road segment along the way. EU rules set a standard ceiling of 18.75 metres for articulated lorries and 16.50 metres for rigid trucks with trailers; certain member states allow modular vehicle combinations – commonly known as longer and heavier vehicles (LHVs) – of up to 25.25 metres under specific permit conditions. These limits reflect safety requirements, turning-radius constraints, and the load-bearing capacity of road infrastructure. For cross-border operations, hauliers must verify the applicable rules in each transit country individually, as thresholds and permit requirements differ considerably. Operating beyond permitted lengths without authorisation exposes carriers to fines and potential operating bans.
