The Highways (Road Humps) Regulations 1999

Nature, dimensions and location of road humps

4.—(1) Subject to regulation 7, no road hump shall be constructed or maintained in a highway unless–

(a) each face of it across the carriageway of the highway in which it is constructed is at right angles to an imaginary line along the centre of that carriageway;

(b) it has a minimum length of 900 millimetres measured parallel to an imaginary line along the centre of that carriageway from the point where one face meets the surface of that carriageway to the point where the other face meets the surface of that carriageway;

(c) the highest point on it is not less than 25 millimetres nor more than 100 millimetres higher than an imaginary line parallel to the centre line of that carriageway connecting the surface of that carriageway on one side of the road hump to the surface of that carriageway on the other side of the road hump and passing vertically below that point; and,

(d) no vertical face of any material forming part of that road hump exceeds 6 millimetres measured vertically from top to bottom of that face.

(2) A road hump may be constructed and maintained in a highway so that an imaginary line along the centre of the hump from one side of the road to the other is in the same position as an imaginary line from one side of the road to the other along the centre of the pattern of black and white stripes specified in paragraph 8(1) of Part II of Schedule 1 to the Zebra, Pelican and Puffin Pedestrian Crossings Regulations and General Directions 1997(1).

(3) Save as mentioned in paragraph (2) above, no road hump shall be within the limits of a zebra controlled area as defined in regulation 3(1) of the regulations mentioned in that paragraph or within 30 metres from the imaginary line along the centre of the pattern of stripes mentioned in that paragraph.

(4) A road hump may be constructed and maintained in the highway so that an imaginary line along the centre of the hump from one side of the road to the other is in the same position as an imaginary line along the centre of the limits of the crossing from one side of the road to the other as shown in a diagram in Part II Schedule 1 to the Zebra, Pelican and Puffin Pedestrian Crossings Regulations and General Directions 1997.

(5) Save as mentioned in paragraph (4) above, no road hump shall be within the limits of a “pelican” crossing as defined in regulation 3(1) of the regulations mentioned in that paragraph or within 30 metres of any part of any such crossing.

(6) No road hump shall be constructed or maintained in a highway:

(a) on a railway level crossing or within 20 metres of any rail forming part of the railway track at any such crossing;

(b) within 2 metres of any rail providing support and guidance for vehicles carried on flanged wheels and running in a carriageway of that highway otherwise than at a railway level crossing;

(c) under or within 25 metres of any part of a structure over a carriageway of that highway any part of which is 6.5 metres or less above the surface of the carriageway; or,

(d) above or within 25 metres of any part of a bridge over which a carriageway of that highway passes or any part of a tunnel, culvert or other similar structure which crosses beneath a carriageway of that highway.
