The Motor Vehicles (Type Approval of Reduced Pollution Adaptations) Regulations 1998
These Regulations prescribe type approval requirements for reduced pollution devices, that is to say devices fitted to the engines of vehicles so as to adapt them to fulfil reduced pollution requirements prescribed under the Vehicle Excise Duty (Reduced Pollution) Regulations 1998. By virtue of amendments made by Schedule 1 to the Finance Act 1998, lower rates of vehicle excise duty apply to vehicles within particular classes in Schedule 1 to the Vehicle Excise and Registration Act 1994, if they meet the reduced pollution requirements.
