§ Mr. Leightonasked the Minister of Transport whether the present taxes on heavy lorries cover the social and environmental costs imposed by these lorries on the community.
§ Mr. FowlerThese costs cannot be measured objectively. However, the contribution in motoring taxation (fuel duty and vehicle excise duty) in 1979–80 from goods vehicles as a whole over 3.5 tons gross weight is estimated to exceed their allocated road costs by about 10 per cent.
