HGVs can now use aerodynamic features to reduce emissions

Changes to legislation will mean that HGV operators can use aerodynamic features to reduce fuel consumption and emissions. 

The new rules will allow haulage companies to choose vehicles with elongated cabs and aerodynamic features fitted on the back, which help to reduce fuel consumption. 

Aerodynamic rear devices are flaps that are fitted on the back of trailers to reduce the vehicle’s aerodynamic drag without using up load space. They were previously not permitted for use on Great Britain’s roads under regulations that have been in place since 1986.

However, a 2013 study estimated that these improvements could result in a fuel-saving of 7%-15%.

Roads Minister Baroness Vere said: ‘This is another brilliant step, not just in our efforts to reduce emissions across our transport network, but also to improve safety on our roads.

‘I hope operators will make use of these new regulations, introducing vehicles with these features into their existing fleets to reduce fuel consumption and boost safety, as we build back better from Covid-19.

The Department for Transport has published good practice guidance on the use of aerodynamic rear devices on HGVs in urban and rural areas.

This follows separate legislation last year to allow greener, longer goods vehicles to be rolled out as the government responded to its consultation on longer-semi trailers reducing mileage, congestion and carbon emissions.

Phil Lloyd, Logistics UK’s Head of Engineering Policy, added: ‘Allowing the use of aerodynamic features and elongated cabs on HGVs is fantastic news for our transport sector, which is looking to improve fuel efficiency and reduce emissions.

‘These features are vital in helping to reduce emissions and improve air quality and Logistics UK welcomes the design of elongated cabs that improve driver vision and provide drivers with much-needed additional comfort space.’
