About the LEZ
The vehicles affected by the LEZ are older diesel-engine lorries, buses, coaches, large vans, minibuses and other heavy vehicles that are derived from lorries and vans, such as motor caravans and motorised horse boxes.
There will be a phased introduction of the scheme from 4 February 2008 through to January 2012. Cars and motorcycles are not affected by the scheme.
