These Regulations modify the Motorways Traffic (England and Wales) Regulations 1982 (“the 1982 Regulations”), in respect of the M42 Motorway, Junctions 3A to 7 and the adjoining slip roads (“the relevant roads”). On the relevant roads, the Regulations introduce variable speed limits and create the concept of an `actively managed hard shoulder', which is a section of hard shoulder which may, in certain circumstances, be driven on.
