We are still over and back discussing it with them. They have exempted a small number of roads that straddle the Border but are still refusing to exempt the A5, which we want exempted. We have been considering, as a potential alternative solution, joining the UK system, introducing the same system in the Republic and reducing the road tax for heavy goods vehicles, HGVs, to compensate them. However, this needs to be worked out between my Department, the Department of the Environment, Community and Local Government, Revenue and a few other people. An interdepartmental committee is working on it.
