The Society of Motor Manufacturers and Traders wants the Department for Transport to tackle the issue of dodgy conversions to vans.

“If a vehicle is converted after it is registered, there is no effective control or way to ensure that it meets any safety standards,” said Allan McKenzie, senior technical manager, legislation at the SMMT.

“We’ve repeatedly told the DfT about this and the potential for vehicle owners to undermine the vehicle approval scheme, either wilfully or in ignorance.”
