Bigger capacity trucks theoretically mean fewer truck movements and less vehicles on the roads
However, UK authorities remain unconvinced about whether there is a permanent place for larger semi-trailers.
The UK Department for Transport has just announced a five-year extension of a long-running trial of longer semi-trailer trucks.
More trucks will also be involved – as many as an extra 1,000.
The trail, which has been running since 2012, involves longer semi-trailers of 14.6 metres and 15.65 metres in length (17.5 metres and 18.55 metres total vehicle lengths respectively).
Despite the added length, the trailers must operate within the UK’s existing domestic weight limit of 44 tonnes for vehicles of 6 axles.
The road authority telling us it was still looking at the environmental and safety benefits of the larger trucks.
The news that the trial would continue has been welcomed by the Freight Transport Association (FTA).
Andy Mair, FTA’s Head of Engineering, says the trial has been hugely successful.
“FTA fully supports any increase in the total number of LSTs under trial, as these types of initiatives will play an important part in the logistics industry’s efforts to reduce carbon emissions.
“Through this trial, industry and Government are working in partnership to understand the benefits – in terms of reduced mileage and therefore emissions – of the larger vehicle type, while keeping a very close eye on safety.”
