The Road Humps Regulations (Northern Ireland) 1999
These Regulations revoke the Road Humps Regulations (Northern Ireland) 1992 (“the 1992 Regulations”) and the Road Humps (Amendment) Regulations (Northern Ireland) 1996 and replace them with new provisions. The principal changes are—A road hump may now be constructed in any road except a special road. Formerly no humps could be constructed in a trunk road or a road which was not subject to a speed limit of 30 miles per hour or less.Humps of any height between 25 millimetres and 100 millimetres are permitted. Formerly the minimum height was 50 millimetres.The shape of a hump is no longer prescribed, but it must have a minimum length of 900 millimetres. The 1992 Regulations prescribed cross sections and hump dimensions by means of diagrams.The positioning of humps is no longer restricted, except in respect of zebra and pelican crossings, railway level crossings, tramways, structures 6£5 metres or less above the carriageway, and bridges, tunnels, culverts or other similar structures over which the carriageway passes, in which cases the former restrictions have been retained.The required lighting of the road hump may now conform to BS 5489 published by the British Standards Institution of 389 Chiswick High Road, London, W4 4AL, as an alternative to the three previous requirements of lamps separated by no more than 38 metres or specially provided lighting or a street lamp within 5 metres of the hump, all of which continue to apply.Particular traffic signs are no longer prescribed. Appropriate traffic signs are now to be placed in such positions so as to provide adequate warning of the presence of a road hump or a series of road humps to persons using the road.
