The Secretary of State, if he is satisfied that it is desirable to do so, may by order made by statutory instrument prohibit or restrict, subject to such exceptions and conditions as to occasional use or access to premises or otherwise as may be specified in the order, the driving of vehicles on all roads of any such class as may be specified in the order.

A prohibition or restriction under this section may be imposed either generally or in relation to any class of vehicle; and for the purposes of this section the Secretary of State may classify roads in any manner he thinks fit, having regard to their character and situation or the nature of the traffic to which they are suited, and may determine in what class any particular road shall be included.

Where, by a notice published as mentioned in section 1(4) of this Act, a date has been or is declared to be the date on which a part of a special road is open for use as a special road, no order under this section shall have effect in relation to that part of the road or (in the case of an order coming into operation before the date so declared) shall have effect in relation to it on or after that date.

A statutory instrument by which an order under this section is made, revoked or varied shall not have effect unless and until it has been approved by a resolution of each House of Parliament.

A person who drives a vehicle, or causes or permits a vehicle to be driven, in contravention of an order under this section shall be guilty of an offence.
