DSA and VOSA to merge The news has been given a guarded welcome by the Road Haulage Association (RHA). Geoff Dunning, the RHA chief executive, said: "This move makes obvious sense to an industry that is surrounded by regulations from number of regulatory bodies. However, we are concerned that this is another case of the devil being in the detail and we would welcome the opportunity to contribute to the negotiations as to how the new system will actually work. We have always had a good relationship with both the DSA and VOSA and are confident that this will continue with the new, single, regulatory body.
