Regulation 18 Traffic Signs

the placing on or near the road of appropriate traffic signs as prescribed in the Traffic Signs Regulations and General Directions 2002^f1, or as specially authorised by the Secretary of State, in such positions (if such positions are not prescribed) as the authority may consider requisite for securing that adequate information as to the designation is made available to persons using the road;

the maintenance of such signs for so long as the designation remains in force; and

in a case where a designation is varied or revoked, the removal or replacement of existing traffic signs as the authority considers requisite to avoid confusion to road users by signs being left in the wrong positions.
