Longer lorries are now allowed on Britain's roads to enable more goods to be carried on fewer journeys.
This is despite fears about the risks for pedestrians and cyclists as the vehicles have a larger tail swing - meaning their rear end covers a greater area when turning - and extended blind spots.
Lorry trailers up to 61ft (18.55m) long - some 6ft 9in (2.05m) longer than the standard size - are allowed to be used from 31 May.
The Department for Transport (DfT) has previously said the new lorries will be able to move the same volume of goods as current trailers in 8% fewer journeys.
The policy is expected to generate £1.4bn in economic benefits and take one standard-size trailer off the road for every 12 trips.
An 11-year trial of longer lorries has demonstrated they are safe for use on public roads, according to the DfT.
The study found they were involved in "around 61% fewer personal injury collisions than conventional lorries", the department said.
A government-commissioned report published in July 2021 revealed that 58 people were injured in incidents involving longer lorries between 2012 and 2020.
Roads minister Richard Holden said: "A strong, resilient supply chain is key to the Government's efforts to grow the economy.
"That's why we're introducing longer semi-trailers to carry more goods in fewer journeys and ensure our shops, supermarkets and hospitals are always well stocked."
However, some organisations are concerned at the move - including Cycling UK.
Its campaigns manager Keir Gallagher said at the time of the government's decision: "At a time when funding for infrastructure to keep people cycling and walking safer has been cut, it's alarming that longer and more hazardous lorries could now be allowed to share the road with people cycling and walking.
"Before opening the floodgates to longer lorries rolling into our busy town centres and narrow rural lanes, further testing in real life scenarios should have been done to assess and address the risks."
Meanwhile, the Road Haulage Association welcomed the move, saying it would "increase productivity, reduce HGV journeys by carrying the same volume of freight in fewer lorries - and reduce mileage, congestion and carbon emissions".
But in a statement, it added: "The government could however go further by increasing the permitted weight to 48 tonnes for moving goods from road to rail.
"This will be increasingly important when we roll out zero-emission trucks to compensate for the increased weight from batteries."
