§ Mr. Biffen
To ask the Secretary of State for Transport if, having regard to safety factors, he will authorise the raising of the 16 tonne gross weight of a two-axle tractor unit in line with the gross weight now allowed for two-axle trucks.
§ Mr. Peter Bottomley
Two-axle tractor units with a minimum axle spacing of 2.7 m have since May 1983 been permitted a gross weight of 17 tonnes provided the vehicle has a total train weight of more than 32.52 tonnes. Statutory Instrument 1987 No. 676 removes that proviso and fixes the maximum gross weight of two-axle rigid lorries also at 17 tonnes. The SI comes into effect on 1 April 1988.
