Details

The Department for Transport began a trial of longer semi-trailers for articulated goods vehicles in January 2012. The operational trial aims to see if using longer semi-trailers brings about anticipated environmental and economic benefits.

A total of 1,800 longer semi-trailers has been allocated to approximately 160 operators. It’s anticipated that the 10 year trial will save 3,000 tonnes of carbon emissions and save operators £33 million. This document presents the findings from the fourth year of the longer semi-trailer trial.
