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.
The devices were previously not permitted for use on Great Britain’s roads under regulations that have been in place since 1986. Studies suggest the aerodynamic improvements to HGVs could result in fuel savings of between 7-15%.
The Government has also given the go-ahead for vehicles with longer cabs. The design of elongated cabs improves driver vision, boosting safety for other road users. The extra space means more comfort for the driver, such as by facilitating a larger bed in sleeper cabs.
Phil Lloyd, Logistics UK’s Head of Engineering Policy, said: “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.”
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.
The Department for Transport has published good practice guidance on the use of aerodynamic rear devices on HGVs in urban and rural areas.
