What Are Longer Semi-Trailers?

Longer Semi-Trailers (LST's), now legal to use on UK roads, are up to 2.050m longer than a standard 13.6m trailer (up to 15.65m) and can carry up to 60 UK pallets (15% greater volume) than their standard length counterparts.

A tractor unit coupled to an LST must not exceed a length of 18.55m in total.

Well suited to light and medium freight operators, the additional cube will reduce delivery frequency, cut down on fuel costs and lower CO2 emissions.

From 31st May 2023, Longer Semi Trailers (LSTs) can be operated on UK roads

A newly amended Road Vehicles (Authorisation of Special Types) (General) Order 2023 allows operators to run LSTs on pre-planned routes with some operational caveats.

The Longer Semi-Trailer trial, which ran from January 2012, ended on 29th February 2024.
