The Road Vehicles and Non-Road Mobile Machinery (Type Approval) (Amendment) (EU Exit) (No. 2) Regulations 2019

These Regulations amend the Road Vehicles and Non-Road Mobile Machinery (Type Approval) (Amendment) (EU Exit) Regulations 2019 (S.I. 2019/648) (“the principal Regulations”) to vary the date for commencement of Part 3 of that instrument (which provides for amendments under the European Communities Act 1972 (c. 68) to be made to definitions in the Road Traffic (Northern Ireland) Order 1981 (S.I. 1981/154 (N.I. 1)). This is necessary due to the late making of the principal Regulations such that Part 3 would not properly commence before exit day.
